CONTACT INFORMATION DISPLAY METHOD AND DEVICE, AND INFORMATION DISPLAY METHOD AND DEVICE

CROSS REFERENCE TO RELATED PATENT APPLICATIONS

This application claims priority to Chinese Patent Application No. 201710135065.0 filed on 8 March 2017 and entitled "CONTACT INFORMATION DISPLAY METHOD AND DEVICE, AND INFORMATION DISPLAY METHOD AND DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD

The present disclosure relates to the field of information processing, and, more particularly, to contact information display methods and devices, and information display methods and devices. BACKGROUND

At present, mobile terminals are mostly equipped with a gesture/digital lock screen function. Unlocking manners generally include sliding fingerprint unlocking, entering a digital password, and so on according to a predetermined track,. Such manners may well protect the privacy of users, so that information in the mobile terminals of the users is prevented from being viewed by others.

Although the gesture/digital lock may protect the privacy of the users, an unlocking interface that pops up when an unlocking function is triggered clearly informs a person who unlocks a mobile terminal that the mobile terminal stores privacy information which should be prevented from being known by others. A good protection function against snoopers is achieved. However, displaying of reminders and repeated unlocking may cause poor user experience. No effective solution has been put forward to solve the problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking. SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify all key features or essential features of the claimed subject matter, nor is it intended to be used alone as an aid in determining the scope of the claimed subject matter. The term "technique(s) or technical solution(s)" for instance, may refer to apparatus(s), system(s), method(s) and/or computer-readable instructions as permitted by the context above and throughout the present disclosure.

According to an aspect of example embodiments of the present disclosure, a contact information display method is provided, which includes: detecting a biometric characteristic of a current user of a terminal; determining whether the biometric characteristic matches a preset biometric characteristic; and determining, based on a judgment result, whether to display first information of a designated contact in the terminal.

According to an aspect of the example embodiments of the present disclosure, a contact information display device is provided, which includes: a detection module configured to detect a biometric characteristic of a current user of a terminal; a judgment module configured to determine whether the biometric characteristic matches a preset biometric characteristic; and a determination module configured to determine, based on a judgment result, whether to display first information of a designated contact in the terminal.

According to another aspect of the example embodiments of the present disclosure, an information display method is further provided, which includes: starting an application (APP) on a terminal; detecting a biometric characteristic of a current user; acquiring an access permission corresponding to the biometric characteristic; and displaying, based on the access permission, content which is displayed by the APP and corresponds to the access permission.

According to another aspect of the example embodiments of the present disclosure, a terminal is further provided, which includes: a processor configured to detect a biometric characteristic of a current user of the terminal, determine whether the biometric characteristic matches a preset biometric characteristic, and determine, based on a judgment result, whether to display first information of a designated contact; and a display device configured to display the first information of the designated contact when the judgment result indicates that the biometric characteristic matches the preset biometric characteristic, or display second information of other contacts except the designated contact in the terminal when the judgment result indicates that the biometric characteristic does not match the preset biometric characteristic.

According to another aspect of the example embodiments of the present disclosure, an information display device is further provided, which includes: a starting module configured to start an APP on a terminal; a detection module configured to detect a biometric characteristic of a current user; an acquisition module configured to acquire an access permission corresponding to the biometric characteristic; and a display module configured to display, based on the access permission, content which is displayed by the APP and corresponds to the access permission.

For a designated contact, a judgment on a user of a current terminal is made by using a biometric recognition technology of the terminal, such as face recognition, fingerprint recognition or iris recognition. Because biometric recognition is unique, accurate and fast, the terminal may accurately determine whether the current terminal user is a preset user having a preset biometric characteristic, and further determine whether to display related information of the designated contact. Thus, the techniques of the present disclosure intelligently determine, through the biometric recognition, whether to display SMS messages and phone calls of the designated contact, thereby meeting the needs of unaware snoop prevention and convenience. In this way, privacy of the terminal user may be guaranteed to prevent privacy information of the user from being snooped by others, and further use convenience for the user may be improved, thereby avoiding unnecessary repeated unlocking.

Thus, the foregoing solution solves the technical problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking.

DETAILED DESCRIPTION

To enable persons skilled in the art to better understand the solutions of the present disclosure, the technical solution in the example embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the example embodiments of the present disclosure. It is apparent that the example embodiments to be described represent only a part of rather than all of the example embodiments of the present disclosure. All other example embodiments derived by persons of ordinary skill in the art based on the example embodiments in the present disclosure without making creative efforts should fall in the scope of the present disclosure.

It should be noted that, the terms "first", "second", and so on in the specification, claims and the drawings of the present disclosure are used to distinguish similar objects, but not necessarily to describe a particular order or sequence. It should be understood that, data used as such may be interchanged under appropriate circumstances, so that the example embodiments of the present disclosure described herein could be implemented in an order other than the order illustrated or described herein. In addition, the terms "comprise/include" and "have" as well as their any variations are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units are not necessarily limited to the steps or units clearly listed, but may include other steps or units not clearly listed or inherent to the process, method, system, product or device. To facilitate understanding of the example embodiments of the present disclosure, technical terms involved in the example embodiments of the present disclosure are explained as follows:

Biometric recognition: each individual has a unique physiological characteristic or behavioral partem that may be measured or automatically recognized and verified, that is, a biometric characteristic (e.g. a fingerprint, facial image, iris, palm print, or the like). Biometric recognition is the use of human physiological or behavioral characteristics to verify personal identity.

Information disguise: real information is disguised as other information that is irrelevant to the real information.

Designated contact: a designated contact is a contact having a particular attribute in an address book (including, but not limited to, a phone book, an address book in instant messaging software, etc.) of a terminal. For example, designated contacts have the following particular attribute: specific information or all information associated with the contacts may be displayed on a terminal where the designated contacts are located only when a certain condition is met (for example, a biometric characteristic of a user of the terminal where the designated contacts are located meets a preset condition). It should be noted that the particular attribute may be a user-defined attribute.

Example embodiment 1

To prevent information of a mobile phone from being viewed by others at will, a commonly taken approach is to lock the screen of the mobile phone. When a user triggers a lock screen key of a mobile terminal or if a mobile terminal does not receive any new instruction in a preset time period, the mobile terminal enters a lock screen state. The user needs to perform an unlocking operation, such as sliding, entering a password or the like, to use the mobile terminal that has entered the lock screen state. In addition, a locking function of an APP may also provide similar protection for information. Such a method may indeed protect information in a mobile terminal from being viewed at will. However, a user needs to unlock the mobile terminal every once in a while to use it again, which is very inconvenient.

To solve the foregoing technical problem, the present disclosure provides a corresponding solution. Description is provided below by using an example in which the terminal is a mobile phone and the APP (Application) is an SMS or phone APP, as shown in FIG. 1 :

Step SI 02. A selection of a user is received, and an APP is started. In the step, for example, a current user clicks on an APP icon, and an APP of a terminal may be started.

Step SI 04. Information input by the user is received, and it is determined whether a designated contact needs to be added. If a phone owner wants to add the designated contact, step SI 08 is performed; otherwise, step SI 06 is performed.

The designated contact that the phone owner adds through the above step may be a contact that the phone owner needs to hide from others.

Optionally, the user may select a contact in an address book as the designated contact to be added, or the user may manually input a phone number, a name, a nickname, a WECHAT ID, a QQ number or other special identification information of the designated contact to add the designated contact. For example, if the user adds Wang XX in a mobile phone address book as the designated contact, APPs such as WECHAT, QQ, and ALIPAY that match the address book all may use Wang XX as the designated contact. Even if Wang XX has different nicknames in multiple APPs, the APPs may still identify Wang XX and use Wang XX as the designated contact based on a matching function between the APPs.

Step S106. The APP is enabled.

The SMS or phone APP is enabled in the case where the phone owner does not add any designated contact.

Step SI 08. Whether biometric recognition is enabled is determined. If the phone owner has enabled the biometric recognition, step SI 12 is performed; otherwise, step S110 is performed.

Optionally, the biometric recognition may be a facelock. The facelock is used for determining whether to display information of the designated contact by identifying facial feature information of the current terminal user. In the step, it is determined whether biometric recognition is enabled when the phone owner determines to add the designated contact.

For example, the phone owner disables the biometric recognition for a game APP and a video entertainment APP of the mobile phone that do not have information related to the designated contact, but enables the biometric recognition for SMS, phone and WECHAT APPs that have or have a chance to receive the information related to the designated contact.

Step SI 10. A regular lock screen interface such as a gesture or digital lock interface pops up. In this step, a regular unlocking interface may be enabled when the user does not enable the biometric recognition, so that information stored in the mobile phone is protected in the event that the user does not enable the biometric recognition.

Step SI 12. Whether the user is the valid user such as a phone owner is determined. For example, the biometric recognition is a facelock. When the user enables a preset

APP in the event that the phone owner enables the facelock, the mobile phone may detect a facial image of a current user by using a front camera and extract a feature of the facial image, to take the acquired facial feature of the current terminal user as the biometric characteristic of the current user. It may be determined whether the current terminal user is the phone owner by matching the facial feature of the current terminal user with a pre-stored facial feature of the phone owner. In this step, a judgment result at least includes either of the following: matching and mismatching. If the facial feature of the current terminal user matches a preset facial image, it may be determined that the current terminal user is the phone owner, and step S116 is performed. If the facial feature of the current terminal user does not match the preset facial image, it may be determined that the current terminal user is not the phone owner, and step SI 14 is performed.

Step SI 14. The APP is launched or started and related information of the designated contact is not displayed.

When the current terminal user is not the phone owner, the mobile phone hides and/or disguises the related information of the designated contact, and launches the SMS or phone APP, without displaying the related information of the designated contact.

Step SI 16. The APP is launched and the related information of the designated contact is displayed.

When the current terminal user is the phone owner, the mobile phone does not hide the related information of the designated contact, and undisguises the information of the designated contact, to restore the information of the designated contact to user identifiable information. After the user launches the SMS or phone APP, the terminal will display all information, including the information of the designated contact.

FIG. 2 is a flowchart of an optional information display method when a judgment result indicates a mismatch according to an example embodiment of the present disclosure. To further describe the foregoing implementation solution, detailed description is provided below with reference to FIG. 2 by using an example in which the terminal is a mobile phone. In this example embodiment, when the result of the judgment on detected characteristic information of the current terminal user indicates a mismatch, the method includes the following steps:

S202. Information related to a designated contact is received or sent.

The information may be an SMS message or a call record, and may also be WECHAT, ALIPAY and other communication records, which is not for example limited here.

S204. It is determined whether the information is from the designated contact.

This step is used for determining whether an SMS message or phone call currently received or sent is from the designated contact. The designated contact is set by the phone owner. If the SMS message or phone call currently received or sent is related to the designated contact, step S206 is performed; otherwise, step S208 is performed.

S206. An SMS message notification or phone interface is disguised in a custom manner.

If the SMS message or phone call currently received or sent is related to the designated contact, an SMS message notification or phone interface is disguised in accordance with a preset or default form, so that the information related to the designated contact cannot be identified by the current terminal user. In an optional example embodiment, for example, first information of the designated contact is an SMS message from the designated contact. In the case where the judgment result indicates a mismatch and the current terminal user is determined not the valid user such as the phone owner. If the terminal receives an SMS message from the designated contact, content of the SMS message from the designated contact is disguised, so that the non-owner user cannot identify the SMS message or phone call from the designated contact. For example, the SMS message from the designated contact may be disguised as a phone bill reminder message or the like sent by a communication corporation.

S208. SMS messages or call records received and sent are stored in an SMS message/call record database.

The SMS messages or call records related to the designated contact may be put in a first SMS message/call record database. The first SMS message or call record database is different from a second SMS message/call record database in which information of other contacts except the designated contact is stored.

S210. The SMS messages or call records received and sent are stored in another database, where the another database is the second SMS message/call record database. Based on the forgoing solution provided in the present disclosure, for a designated contact, a judgment on a user of a current terminal is made by using a biometric recognition technology of the terminal, such as face recognition, fingerprint recognition or iris recognition. Because biometric recognition is unique, accurate and fast, the terminal may accurately determine whether the current terminal user is a preset user having a preset biometric characteristic, and further determine whether to display related information of the designated contact. Thus, it may be intelligently determined, through the biometric recognition, whether to display SMS messages and phone calls of the designated contact, meeting the needs of unaware snoop prevention and convenience. In this way, privacy of the terminal may be guaranteed to prevent privacy information of the user from being snooped by others, and further use convenience for the user may be improved, thereby avoiding unnecessary repeated unlocking.

Example embodiment 2

In order to solve the technical problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking, the present disclosure further proposes the following solution. In the following, description is provided by using an example in which the terminal is a mobile phone and the APP is an SMS or phone APP, as shown in FIG. 3 :

Step S302. A selection of a user is received to start an APP (Application).

In this step, for example, a current user clicks on an APP icon, and an APP of a terminal is started.

Step S304. Information input by the user is received, and whether a designated contact needs to be added is determined.

If a phone owner adds a designated contact through this step, the added contact is the designated contact, which may be a contact that the phone owner needs to hide from others. If the phone owner intends to add a designated contact, step S308 is performed; otherwise, step S306 is performed.

Step S306. The APP is enabled.

The SMS or phone APP is enabled in the case where the phone owner does not add any designated contact.

Step S308. Whether biometric recognition is enabled is determined. If the phone owner has enabled the biometric recognition, step S312 is performed; otherwise, step S310 is performed. Optionally, the biometric recognition may be a facelock. The facelock is used for determining whether to display information of the designated contact by identifying facial feature information of the current terminal user. In this step, it is determined whether biometric recognition is enabled if the phone owner determines to add the designated contact. For example, the phone owner disables the biometric recognition for a game APP and a video entertainment APP of the mobile phone that do not have information related to the designated contact, but enables the biometric recognition for SMS, phone and WECHAT APPs that have or have a chance to receive the information related to the designated contact.

Step S310. A regular lock screen interface such as a gesture or digital lock interface pops up.

In this step, a gesture or digital lock interface pops up if the user does not enable the biometric recognition.

Step S312. An access permission of the user is determined.

It should be noted herein that, one or more biometric characteristics and one or more access permissions corresponding to the one or more biometric characteristics may be input to the terminal before an access permission of the user is determined. Therefore, after being detected, the biometric characteristic of the current user may be matched with the pre-stored biometric characteristics, so that an access permission corresponding to a biometric characteristic matching the current user is assigned to the current user.

In an optional example embodiment, a mobile phone has three access permissions: A,

B and C. Access permission A allows access to all content of the mobile phone, and the corresponding biometric characteristic is a biometric characteristic of the phone owner. Access permission B allows access to related content of other contacts except designated contact X, and the corresponding biometric characteristic is a biometric characteristic of a family member of the phone owner. Access permission C allows access to related content of other contacts except designated contacts X and Y, and the corresponding biometric characteristic is another biometric characteristic that does not match the pre-stored biometric characteristics.

S314. The APP is launched or started and content corresponding to the access permission of the user is displayed.

In the foregoing example embodiment, if it is detected that the biometric characteristic of the current terminal user matches the biometric characteristic corresponding to access permission A, all information in the APP is displayed to the current user. If it is detected that the biometric characteristic of the current terminal user matches the biometric characteristic corresponding to access permission B, related content of other contacts except contact X in the APP is displayed to the current user. If it is detected that the biometric characteristic of the current terminal user does not match any of the pre-stored biometric characteristics, related content of other contacts except contacts X and Y is displayed to the current user.

It should be noted herein that, during message receiving and transmission with contacts, content related to contacts X and Y and content related to other contacts except contacts X and Y may be stored in different databases respectively, so that corresponding display content is invoked from a corresponding database according to an access permission after the access permission of the current user is determined.

In the foregoing embodiments, an access permission of the current terminal user on the terminal may be determined by using a face recognition device, a fingerprint recognition device, an iris recognition device, or other biometric recognition devices of the terminal. Because biometric recognition is unique, accurate and fast, the terminal may accurately compare a biometric characteristic of the current terminal user with a pre-stored biometric characteristic, to determine an access permission corresponding to the biometric characteristic of the current terminal user, and then display corresponding content according to the access permission of the current terminal user. Thus, it may be intelligently determined, through the biometric recognition, whether to display SMS messages and phone calls of the designated contact, meeting the needs of unaware snoop prevention and convenience. In this way, privacy of the terminal may be guaranteed to prevent privacy information of the user from being snooped by others, and further use convenience for the user may be improved, thereby avoiding unnecessary repeated unlocking.

Thus, the foregoing solution solves the technical problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking.

It should be noted herein that, in some optional example embodiments, the mobile equipment shown in FIG. 4 may include hardware elements (including circuits), software elements (including computer code stored in a computer readable medium), or a combination of the hardware elements and the software elements. It should be pointed out that FIG. 4 is merely an instance of a specific example embodiment, and is intended to illustrate the types of members that may be stored in the mobile equipment. In the foregoing running environment, to solve the problem that it is inconvenient to use the mobile equipment as the user needs to unlock the mobile equipment each time using it, the present disclosure provides a contact information display method as shown in FIG. 5. FIG. 5 is a flowchart of a contact information display method according to Example embodiment 1 of the present disclosure. The contact information display method includes the following steps:

Step S502. A biometric characteristic of a current terminal user is detected.

For example, the biometric characteristic may be an iris characteristic, a facial characteristic, a fingerprint characteristic or the like. The biometric characteristic of the current terminal user may be detected by using a variety of devices on a mobile terminal. For example, if the current terminal is a mobile phone, a device for detecting the biometric characteristic of the current terminal user may be a camera of the mobile phone, a fingerprint detection device of the mobile phone, or the like.

Step S504. Whether the biometric characteristic matches a preset biometric characteristic is determined.

In this step, in consideration of an environmental influence on the detection, it may be determined that the biometric characteristic of the current terminal user matches the preset biometric characteristic if a degree of similarity between the biometric characteristic of the current terminal user and the preset biometric characteristic reaches a preset threshold. This step is mainly used for determining whether the current terminal user is a preset user by matching biometric characteristics, where the preset user is a user having the highest permission to use the current terminal.

Step S506. Based on a determined result, whether to display first information of a designated contact in the terminal is determined.

For example, the first information of the designated contact may be an information record or call record between a preset user and the designated contact, and may also be information such as an image including the designated contact.

It should be noted herein that, in the foregoing solution, for a designated contact, a judgment on a user of a current terminal is made by using a biometric recognition device of the terminal, such as a face recognition device, a fingerprint recognition device or an iris recognition device. Because biometric recognition is unique, accurate and fast, the terminal may accurately determine whether the current terminal user is a preset user having a preset biometric characteristic, and further determine whether to display related information of the designated contact. Thus, it may be intelligently determined, through the biometric recognition, whether to display SMS messages and phone calls of the designated contact, meeting the needs of unaware snoop prevention and convenience. In this way, privacy of the terminal may be guaranteed to prevent privacy information of the user from being snooped by others, and further use convenience for the user may be improved, thereby avoiding unnecessary repeated unlocking.

Thus, the foregoing solution solves the technical problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking.

In the foregoing example embodiment of the present disclosure, step S506 of determining, based on a judgment result, whether to display first information of a designated contact in the terminal includes the following steps:

Step A. The first information of the designated contact is displayed when the determined result indicates that the biometric characteristic matches the preset biometric characteristic.

In this step, the first information of the designated contact is displayed if the judgment result indicates that the biometric characteristic of the current terminal user matches the preset biometric characteristic. In an optional example embodiment, still by taking the terminal being a mobile phone as an example, the mobile phone may display all information stored in the mobile phone if the judgment result indicates that the biometric characteristic matches the preset biometric characteristic. The all information definitely includes the first information of the designated contact in the mobile phone. In other words, in this example, the terminal does not hide the first information of the designated contact if the judgment result indicates that the biometric characteristic matches the preset biometric characteristic.

Step B. Second information of other contacts except the designated contact in the terminal is displayed when the determined result indicates that the biometric characteristic does not match the preset biometric characteristic.

In this step, the first information of the designated contact is hidden when the biometric characteristic of the current terminal user does not match the preset biometric characteristic. In an optional example embodiment, still by taking the terminal being a mobile phone as an example, the mobile phone may display second information of other contacts except the first contact when the judgment result indicates that the biometric characteristic does not match the preset biometric characteristic. In other words, in this example, the terminal hides the first information of the contact if the judgment result indicates that the biometric characteristic does not match the preset biometric characteristic.

In the foregoing example embodiment of the present disclosure, step A of displaying the first information of the designated contact when the judgment result indicates that the biometric characteristic matches the preset biometric characteristic includes the following step:

The first information of the designated contact is invoked from a first database when the judgment result indicates that the biometric characteristic matches the preset biometric characteristic, wherein the first database is different from a second database used for storing the second information of the other contacts.

In an optional example embodiment, the first information of the designated contact is stored in a first database, and second information of other contacts except the designated contact is stored in a second database. The terminal invokes the first information of the designated contact from the first database if the judgment result indicates that the biometric characteristic matches the preset biometric characteristic. Moreover, the terminal may also invoke the second information from the second database.

In the foregoing example embodiment of the present disclosure, step A may be implemented in, but not limited to, the following manner: The first information is undisguised to obtain content identifiable to the terminal user; and the identifiable content is displayed.

If the judgment result indicates that the biometric characteristic matches the preset biometric characteristic, and an SMS message is received from the designated contact in the event that the current terminal user is the phone owner, the SMS message from the designated contact is undisguised and displayed in the form of an original SMS message that may be read by the phone owner.

It may be known from the above that, the first information may be undisguised when the judgment result indicates that the biometric characteristic matches the preset biometric characteristic, so that the phone owner may identify the first information related to the designated contact.

In the foregoing example embodiment of the present disclosure, the first information is acquired in the following manner: receiving third information of a current contact; determining whether the third information is related to the designated contact, and taking the third information as the first information of the designated contact when the third information is related to the designated contact.

In the foregoing solution, after new information is received, the received information is first classified based on whether the information is related to the designated contact, and then is stored according to the classification result. If related to the designated contact, the received information is determined as the first information and may be stored in the first database. If not related to the designated contact, the received information is stored in the second database.

In an optional example embodiment, the terminal being a mobile phone is still taken as an example, and the designated contact is A. In the event that the mobile phone receives a new SMS message, the SMS message is taken as the first information and stored in the first database if a source number of the SMS message is the number of the contact A or content of the SMS message includes the name of designated contact A. If irrelevant to the designated contact A, the SMS message is taken as second information and stored in the second database.

In the foregoing example embodiment of the present disclosure, whether the third information is related to the designated contact is determined in one of the following manners: determining whether the third information includes identification information of the designated contact; and determining whether the current contact is identical with the designated contact.

For example, the identification information may be a name, a code name, or the like, and it may be determined whether the current contact is identical with the designated contact based on an information source (e.g., a phone number, a WECHAT ID, a QQ number, or the like).

In the foregoing example embodiment of the present disclosure, the first information is information displayed by an APP currently running in the terminal.

In an optional example embodiment, still by taking the terminal being a mobile phone as an example, if APPs currently running in the terminal include WECHAT, SMS, call, and ALIPAY, the first information is information related to the designated contact in the WECHAT, SMS, call, and ALIPAY APPs.

Before the biometric characteristic of the current terminal user is detected, the method further includes: starting the APP of the terminal.

Optionally, the APP may be all APPs in the terminal, and may also be a designated APP. For example, if the user needs to protect information only about contact A in ALIPAY, the user makes corresponding setting in the ALIPAY APP. If the ALIPAY APP in the mobile phone is not running when the mobile phone is triggered, detection on the biometric characteristic of the current terminal user is not enabled. If the ALIPAY APP in the mobile phone is running on a current interface or is running in the background, the mobile phone starts the step of detecting the biometric characteristic of the current terminal user, to protect the information about contact A in ALIPAY.

It should be noted that, for ease of description, the foregoing method example embodiments are all described as a series of action combinations. However, persons skilled in the art should understand that the present disclosure is not limited to the described sequence of the actions, because some steps may be performed in another sequence or at the same time according to the present disclosure. In addition, persons skilled in the art should also understand that the example embodiments described in this specification are all example embodiments, and the involved actions and modules are not necessarily required by the present disclosure.

Based on the foregoing description of the implementations, persons skilled in the art may clearly understand that the methods according to the foregoing example embodiments may be implemented by software plus a necessary universal hardware platform, and certainly may also be implemented by hardware, but the former is a better implementation in most situations. Based on such understanding, the technical solution of the present disclosure essentially, or the portion contributing to the prior art may be embodied in the form of a software product. The computer software product may be stored in a storage medium (such as a Read-Only Memory (ROM)/Random Access Memory (RAM), a magnetic disk, or an optical disc), and include several instructions to enable terminal equipment (which may be a mobile phone, a computer, a server, a network device, or the like) to execute the methods in the example embodiments of the present disclosure.

Example embodiment 4

In the foregoing running environment, to solve the problem that it is inconvenient to use a mobile terminal as a user needs to unlock the mobile terminal each time using it, the present disclosure provides an information display method as shown in FIG. 6. FIG. 6 is a flowchart of an information display method according to Example embodiment 1 of the present disclosure. The information display method includes the following steps:

Step S602. An APP on a terminal is started.

Step S604. A biometric characteristic of a current user is detected. For example, the biometric characteristic may be an iris characteristic, a facial characteristic, a fingerprint characteristic, or the like. The biometric characteristic of the current terminal user may be detected by using a variety of devices on a mobile terminal. By taking the current terminal being a mobile phone as an example, the device for detecting the biometric characteristic of the current terminal user may be a camera of the mobile phone, a fingerprint detection device of the mobile phone, or the like.

In an optional example embodiment, by taking the current terminal being a mobile phone as an example, when the user starts the APP on the terminal, the mobile phone may detect a facial image of the current user by using a front camera and extract a characteristic of the facial image, to use the acquired facial characteristic of the current terminal user as the biometric characteristic of the current user. In another optional example embodiment, still by taking the current terminal being a mobile phone as an example, if the user unlocks the mobile phone in a dormant state by using a fingerprint, the mobile phone may detect fingerprint information of the current user and extract a fingerprint characteristic of the current user as the biometric characteristic of the current user.

Step S606. An access permission corresponding to the biometric characteristic is acquired.

Step S608. Content which is generated by the APP and corresponds to the access permission is displayed according to the access permission.

It should be noted herein that, in the foregoing solution, for a designated contact, a judgment on a user of a current terminal is made by using a biometric recognition device of the terminal, such as a face recognition device, a fingerprint recognition device or an iris recognition device. Because biometric recognition is unique, accurate and fast, the terminal may accurately compare a biometric characteristic of the current terminal user with a pre- stored biometric characteristic, to determine an access permission corresponding to the biometric characteristic of the current terminal user, and then display corresponding content according to the access permission of the current terminal user. Thus, it may be intelligently determined, through the biometric recognition, whether to display SMS messages and phone calls of the designated contact, meeting the needs of unaware snoop prevention and convenience. In this way, privacy of the terminal may be guaranteed to prevent privacy information of the user from being snooped by others, and further use convenience for the user may be improved, thereby avoiding unnecessary repeated unlocking. Thus, the foregoing solution solves the technical problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking.

It should be noted that, for ease of description, the foregoing method example embodiments are all described as a series of action combinations. However, persons skilled in the art should understand that the present disclosure is not limited to the described sequence of the actions, because some steps may be performed in another sequence or at the same time according to the present disclosure. In addition, persons skilled in the art should also understand that the example embodiments described in this specification are all example embodiments, and the involved actions and modules are not necessarily required by the present disclosure.

Based on the foregoing descriptions of the implementation manners, persons skilled in the art may clearly understand that the methods according to the foregoing example embodiments may be implemented by software plus a necessary universal hardware platform, and certainly may also be implemented by hardware, but the former is a better implementation in most situations. Based on such understanding, the technical solution of the present disclosure essentially, or the portion contributing to the prior art may be embodied in the form of a software product. The computer software product may be stored in a storage medium (such as a ROM/RAM, a magnetic disk, or an optical disc), and include several instructions that enable terminal equipment (which may be a mobile phone, a computer, a server, a network device, or the like) to execute the methods in the example embodiments of the present disclosure.

Example embodiment 5

To solve the problem that it is inconvenient to use a mobile terminal as a user needs to unlock the mobile terminal each time using it, the present disclosure provides a terminal as shown in FIG. 7. FIG. 7 is a schematic structural diagram of a terminal according to an example embodiment of the present disclosure. The terminal includes a processor 702 and a display device 704:

The processor 702 is configured to detect a biometric characteristic of a current user of the terminal; determine whether the biometric characteristic matches a preset biometric characteristic; and determine, based on a judgment result, whether to display first information of a designated contact in the terminal.

For example, the biometric characteristic may be an iris characteristic, a facial characteristic, a fingerprint characteristic, or the like. The biometric characteristic of the current terminal user may be detected by using a variety of devices on a mobile terminal. By taking the current terminal being a mobile phone as an example, a device for detecting the biometric characteristic of the current terminal user may be a camera of the mobile phone, a fingerprint detection device of the mobile phone, or the like. The first information of the designated contact may be an information record or call record between a preset user and the designated contact, and may also be information such as an image including the designated contact.

In an optional example embodiment, still by taking the terminal being a mobile phone as an example, when the mobile phone in a dormant state is triggered to wake up, the mobile phone detects a facial image of the current user by using a front camera and extract a characteristic of the facial image, to take the acquired facial characteristic of the current terminal user as the biometric characteristic of the current user. In another optional example embodiment, still by taking the current terminal being a mobile phone as an example, if the user unlocks the mobile phone in a dormant state by using a fingerprint, the mobile phone may detect fingerprint information of the current user and extract a fingerprint characteristic of the current user as the biometric characteristic of the current user.

In the foregoing solution, in consideration of an environmental influence on the detection, it may be determined that the biometric characteristic of the current terminal user matches the preset biometric characteristic if a degree of similarity between the biometric characteristic of the current terminal user and the preset biometric characteristic reaches a preset threshold. The foregoing step is mainly used for determining whether the current terminal user is a preset user by matching biometric characteristics. The preset user is a user having the highest permission to use the current terminal.

The display device 704 is configured to display the first information of the designated contact when the judgment result indicates that the biometric characteristic matches the preset biometric characteristic; or display second information of other contacts except the designated contact in the terminal when the judgment result indicates that the biometric characteristic does not match the preset biometric characteristic.

In the foregoing solution, the judgment result at least includes either of the following: matching and mismatching. If the biometric characteristic of the current terminal user matches the preset biometric characteristic, it is determined that the current terminal user is a preset user. In this case, the terminal displays the first information of the designated contact. If the biometric characteristic of the current terminal user does not match the preset biometric characteristic, it is determined that the current terminal user is not the preset user. In this case, the terminal hides the first information of the designated contact.

It should be noted herein that, in the foregoing solution, for a designated contact, a judgment on a user of a current terminal is made by using a biometric recognition device of the terminal, such as a face recognition device, a fingerprint recognition device or an iris recognition device. Because biometric recognition is unique, accurate and fast, the terminal may accurately determine whether the current terminal user is a preset user having a preset biometric characteristic, and further determine whether to display related information of the designated contact. In this way, privacy of the terminal may be guaranteed to prevent privacy information of the user from being snooped by others, and further use convenience for the user may be improved, thereby avoiding unnecessary repeated unlocking.

Thus, the foregoing solution solves the technical problems of inconvenience and poor privacy protection effects of an existing terminal caused by repeated unlocking.
