CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to US Non-Provisional Patent Application No. 17/245,069, filed on April 30, 2021, which claims priority to US Provisional Patent Application No. 63/025,656, filed on May 15, 2020.

BACKGROUND

Field

[0002] The present invention relates to a methodology, server, system, and software for secure document verification and management.

Background Information

[0003] Legal documents have been used for centuries for regulating business and other activities of everyday life. Such documents range from banknotes, wills, contracts, certificates, etc. and are used by every “civilized” society since the discovery of paper and its predecessors (like parchment, etc.). Such legal documents need to be authenticated and some sort of verification is needed to ensure that they are either originals, or certified copies. Typically, signatures, stamps or seals are used as means for authentication and verification. In older times, when the reproduction of documents, and of the means for authenticating and verifying them, were not accessible to the general public, such means were very effective in ensuring that the legal documents bearing these means were protected from illegal copying, or falsification by altering their content even in cases where a malicious person falsified a signature, since no person could easily falsify stamps and seals. So, the combined use of these means increased security against illegal acts for copying and falsifying documents.

[0004] In more recent years, technological advances in printing technology, as well as in stamping, made it easier for malicious persons and organizations to falsify documents and/or to illegally copy them.

[0005] Another long-established method for protecting legal documents was to include, among other security features (such as signatures, stamps and seals), a watermark. A typical example is a banknote. A watermark is a symbol or image embedded in a paper document during the production of the paper used in the document, or printed or stamped on the paper at a processing stage after the paper production, and before, during, or after printing the textual and/or visual content of the legal document. Watermarks may also be combined with paper made of special first materials or with a process that gives the paper special features not available in ordinary papers. Such paper making and watermarking technologies are strictly regulated and made available, typically, to governments, and specifically authorized third parties, thus keeping these technologies out of reach of the general public, non-authorized companies, and potential malignant persons.

[0006] Again, technological advances and illegal trade have made access to watermarking technologies easier than ever before. Nowadays, certain kinds of security printers can even be ordered on-line and delivered at one’s doorstep in a matter of hours or days. So, watermarking and use of special papers is not as effective as it once was. [0007] The last 2-3 decades and the rapid computer technology developments have brough a universal use of electronic documents which one can download and print at his personal printer. Such documents also need to be authenticated and their printing to be controlled, so as to avoid illegal duplicates and falsification by altering the document content. Technologies like electronic signatures have been introduced, which are now widespread and used even in ordinary software packages and services (e.g. DocuSign, HelloSign, Adobe Sign, etc.). To electronically sign a secure document, the user’s or the recipient’s computing apparatus, connects with an electronic signature server, or with an electronic signature module in the server.

[0008] Such products use features like digital watermarks, timestamps, and electronic signatures, embedded in digital files in some form of metadata accompanying the content of the document.

[0009] When a document is ready to be signed, the creator specifies which fields need a response, enters the signer’s email address and hits the send button. The forms will then appear in the signer’s inbox with a unique, secure browser link. The signer does not need to download any apps or register for an account; they can just sign the document directly from the link. After the signature is received, the creator will get a notification that the signed document is ready. The authority or company managing the signing process may also send expiration alerts and signature reminders if the signer does not respond. When the document is complete, it is automatically archived and a final copy is sent to both parties.

[0010] Such solutions are very efficient in speeding up signing processes but do not necessarily guarantee that the final copies received by the two signing parties are exact copies of the original or that a third party has not falsified the content of the document. It is even possible for one of the receiving parties to falsify the signed document by altering its content and reprint it with a copy of the same electronic signatures that were included in the original signed document.

[0011] Based on the above problems identified for printed and electronic documents, there is a clear need for a server, system, and software that can regulate and safeguard printing, distribution and management of legal documents in a secure, tamper-proof way and which allows for easy verification of the validity of the content of printed and electronic documents.

SUMMARY

[0012] The present innovative solution solves the problem of managing secure documents so that they can be verified, and protected from tampering and illegal printing. [0013] A legal document is converted to a secure document by embedding into the legal document one or more security codes that have been encrypted with a standard of proprietary cryptographic algorithm. The security codes are supplemented by a QR code associated with the identification of each page of the secure document, and stored at a server or database. The security codes stored in the document and can be printed together with the document, as a form of watermark, using UV-sensitive ink or toner at a security printer. The security codes are encrypted and can be printed on varying locations in the secure document pages, which are defined in a geolocation template, separately transmitted in encrypted format.

[0014] The security codes can be generated with a random security code generator, or using a statistical analysis module of the content of the secure document, or a natural language analysis module of the content of the secure document.

[0015] A timestamp is added every time the document is signed, amended, or printed.

[0016] The secure document can be associated with a number of attributes, like an account number at the server, a project number, an owner, a person authorized to access or print it, etc. [0017] The secure document is archived and an electronic copy can be transmitted to a recipient for signing, amending, or printing.

[0018] The techniques of the present invention are implemented by a method, server, system and software running on the server.

[0044] Adding security codes to legal documents

[0045] FIG.l shows a flowchart of the main steps of the invention. Methodology 100 starts with a user, e.g., a human client, a company employee, or a computer system acting on behalf of the client or employee, connecting to a secure document server, termed a server (and which in alternative exemplary embodiments is a modified Customer Relationship Management (CRM) server), and selecting to create a new document 110. The server associates 120 the created document file with the client’s or employee’s credential and/or his choice of a corporate profile, project, document owner, and person allowed to process the document (other parameters may also be used) and prompts the user to enter the desired number of pages for the newly created document 130. The user may also enter any number of parameters associated with the document (e.g., a document description, state, owner, etc.).

[0046] In an alternative exemplary implementation, the user may upload to the server an existing digital document, instead of creating a new one in step 110.

[0047] Upon the user entering the desired number of pages for the new document, the server creates a set of security codes 140 for each page of the document. Any number of security codes may be used per page for increasing security and different sets of security codes are typically created for each page. These security codes are created using one or more random security code generators and/or cryptographic algorithms. For instance, a random security code generator module in the server, or at a random security code generator server connected with the server, is used to produce the random security codes. [0048] In first variation of the present exemplary embodiments, the security codes are created using a statistical analysis module in the server, or at a statistical analysis server connected to the server, which analyzes the content of the corresponding page of the security document and creates one or more strings used as security codes.

[0049] In a second variation of the present exemplary embodiments, the security codes are created using a natural language analysis module in the server, or at a natural language analysis server connected to the server, which analyzes the language content of the corresponding page of the security document and one or more strings used as security codes.

[0050] As an optional feature, the created security codes may be divided into fragments of the security codes and recombined (i.e., scrambled) to new security codes by mixing and matching fragments from one security code with fragments from another security code within the same set of security codes (i.e., from the security codes associated with the same document page) or with security codes from other sets of security codes (i.e., from the security codes associated with the other pages of the same document). The security codes are used to identify and verify each page of the document that is in possession of a person or system and can be used to compare it with an original electronic file of the document, archived by the server or other computing apparatus or database accessible by the server.

[0051] Together with the security codes, a new Quick Response (QR) code is created 150 for each page, and associated with the corresponding page of the document. The QR code is a visual representation of the identity of the document stored by the server or other computing apparatus or database accessible by the server, where the original electronic file is archived together with metadata associating the secure document with security codes, owner, editor, timestamps, etc.

[0052] The security codes and the QR code for each page of the document are embedded into the content of the corresponding page of the legal document prior to the server dispatching the document to a recipient (e.g., the owner of the document, or a third person or legal entity). This way, the server ensures that the electronic copy of the archived document has all the security features needed to verify and regulate the use of the document copy for the purpose of preventing illegal activities like falsification by altering the content of the document, creation of illegal copies, or illegal printing of the document (e.g. only a single hard-copy may be allowed to be printed).

[0053] The security codes are typically embedded 160 in the electronic copy of the document as metadata in encrypted format so as to prevent any human or legal entity, or computing apparatus, system, or software to tamper them or modify them for falsifying the document or for any other malicious purpose. The encryption is done using any standard cryptographic algorithm (e.g., Advanced Encryption Standard (AES)-256) and/or proprietary cryptographic algorithms, which are paired, one for encryption and one for decryption with corresponding encryption and decryption keys. These cryptographic algorithms may be used either in a cryptography module in the server, or at a cryptography server connected to the server.

[0054] The secure document (with the embedded metadata) is archived 170 at the server or other computing apparatus or database accessible by the server.

[0055] Any time the owner of the secure document edits the document 180, the security codes embedded in the document are updated by the server 190, and the secure document, with the updated security codes, is archived again 170.

[0056] Updating of the security codes 190 may also be performed by the server, every time the secure legal document is signed (e.g., when a contract is signed by the two or more contracting parties), printed, or duplicated. During these actions, a timestamp is also added to the metadata archived by the server and embedded to the secure document prior to distribution.

[0057] Printing security codes as watermarks to legal documents [0058] FIG.2 is a diagram showing how a print copy of the electronic document is created. Every time a copy of the secure legal document is needed, the owner of the document has the option of requesting a certified printed copy be printed by the server and dispatched to his address or to any other address he requests, or for receiving a certified electronic copy of the document and printing the certified copy himself.

[0059] In order to print a certified copy, the security codes and the QR codes need to be printed in a way that they certify that the document content is an exact copy of the archived original at the server or other computing apparatus or database accessible by the server. The current invention solves this problem by using a novel watermarking method. [0060] An ordinary printer is used to print the secure document text (e.g. the content of a contract) on the front pages of sheets of paper of a size selected by the user when creating the new document, or of the size of the uploaded document.

[0061] On the back pages of the same sheets of paper the ordinary printer prints the QR code of the corresponding page. For special circumstances, there is an option to print the QR code on the front of the sheet within the header, footer or margin area. [0062] Since no security codes or other security features are printed or otherwise included on the first page, for not altering the content of the document copy, these security codes are printed at the corresponding back pages of the same sheets, where the QR codes are printed. There is an exception of a special option to include the QR codes on the front page, in the header, footer or margin area of the page. The security codes are printed as a form of watermark. Although watermarking technology is known for many years, the present innovative solution uses a security printer to print invisible watermarks with Ultra Violet (UV)-visible ink or toner. The watermarks are visible only under UV light and thus invisible to human eye, forming a first layer of protection.

[0063] Optionally, the UV-sensitive ink or toner used to print the watermark security codes is selected so as to be visible to only a narrow range of UV light wavelengths. The user or computing apparatus trying to read the watermark should either known the appropriate wavelength of the UV-sensitive ink or toner, or be equipped with a UV light of varying wavelength and scan the back page of the document for reading the watermark. As a result, in order to falsify a printed document (i.e., its printed content on the front page of the paper sheet) the falsifier must be able to read the UV-sensitive watermark and then reproduce it in a falsified printed copy.

[0064] As a second level of protection, the location of the security code watermarks needs to be known in order to read the security codes and reconstitute them, since the printed security code watermarks may be scrambled security codes created from combining segments of the original security codes in a single page or among several pages of the document. In order to safeguard the robustness of the method against attacks, location of the security code watermarks is defined in a geolocation template (e.g. one per page or per document) which is encrypted, archived, and transmitted to the user in the same, or in a separate communication session, or via a separate communication link. In a one aspect the decryption key for the geolocation template is sent by the server to the recipient via a different communication link (e.g. as an OTP sent via Sort Messaging System (SMS) to the user’s mobile telephone device).

[0065] As a third level of protection, the security codes are encrypted with one or more strong standard or proprietary encryption algorithms.

[0066] With the above security measures, a certified copy may be printed by the server and dispatched to the user, or the user may print the certified copy himself and then distribute it to any recipient. [0067] Optional electronic signatures may be embedded in the secure document, using any known or proprietary e-signature protocol or software (e.g., AdobeSign, DocuSign, HelloSign, etc.).

[0068] In a variation of the above exemplary embodiment, the UV watermarks are printed on the front pages of the printed document, e.g., at the border so as not to overlap the document content.

[0069] Referring to FIG.2, an example contract is presented, having Page 1 (i.e., the 1 st front page of document XYZ) 210, which contains a title and paragraphs 1-4, and Page 2 (i.e., the 2 nd front page of document XYZ) 240, which contains paragraphs 5-7, signature/date field 1, and signature/date field 2. Pages 1 and 2, 210, 240 are printed with an ordinary printer (e.g., an inkjet or laser printer).

[0070] The back of pages 210, 240, i.e., back pages 220, 250, are also printed with

QR code 1 and QR code 2, 225, 255, respectively, using the same or other ordinary printer. [0071] Back pages are also printed with a first set of security codes 235, 265, respectively, using a security printer and UV-sensitive ink or toner. The position of the security codes 235, 265 of each set of security codes printed on back pages 220, 250 may be different. This feature can be used so as to make it difficult to detect them. Even if they are detected, their unscrambling and decryption to recreate the original security codes is not obvious. One has to be given both the templates used to create and locate these codes and also the decryption keys for each page.

[0072] The same process may also be used in the exemplary embodiment where the security codes are printed on the border of front pages 210, 240 using UV-sensitive ink or toner.

[0073] System Diagram

[0074] FIG.3 shown an exemplary system diagram of a system used to implement the present innovative solution. System 300 is designed as a central management computing apparatus for handling the creation and archiving of secure documents, their management and printing, the management of client accounts and projects, and the communication with external computing apparatuses and systems. Server 300 has a database 315 (or in alternative embodiments is connected to a database sever 315) used for archiving the secure documents and the associated metadata. Server 310 is also connected to an ordinary printer 320 and to a security printer 325, for printing the document content and the security code watermarks. In an alternative exemplary embodiment, only security printer 325 is used, which printer has the capability to print using both visible (i.e., under visible light) and invisible (i.e., UV-visible) inks or toner. [0075] Server 310 is also connected to an e-signature server 340 (e.g., a third-party server offering commercial e-signature services), a security code server 330 (i.e., a server creating security codes), and an encryption server 350 (i.e., a server creating encryption and decryption keys and using encryption and decryption algorithms for encrypting and decrypting the security codes). In alternative exemplary embodiments, some or all servers 330, 340, 350 are replaced by specialized hardware and/or software modules inside server 310.

[0076] Server 310 is connected, via a data connection, with one or more computing apparatuses 360, which are used by users to connect to server 310 for creating or uploading documents, editing, signing, managing, printing and paying for the security documents they order or consume as services offered by server 310. Computing apparatuses 360 send documents (not secured) and metadata relating to actions (e.g., printing, signing or editing the secure documents) to server 310, while they receive from server 310 secure documents (which have embedded security and QR codes, and also a print-count flag to ensure that the secure document can only be printed once by the user or by the recipient the user wants to send the document to.

[0077] Computing apparatus 360 may optionally be connected to an ordinary printer 370 and to a security printer 375, for printing the document content and the security code watermarks. In an alternative exemplary embodiment, only security printer 375 is used, which printer has the capability to print using both visible (i.e., under visible light) and invisible (i.e. UV-visible) inks.

[0078] Computing apparatus 360 may also be optionally connected with e-signature server 365, and encryption server 367, which may be the same as e-signature server 340 and encryption server 350, which are connected to server 310.

[0079] Software Architecture

[0080] FIG.4 shows an exemplary software architecture for the secure document server 310. Software architecture 400 shows the main software components of the secure document server. Other components may also be used or some of the illustrated components may be omitted or combined to form new components with the same capabilities of the merged components. [0081] Software architecture 400 has an account manager 410 for managing user accounts, document manager 415 for managing secure documents, a security code manager 420 for managing the security codes that are embedded into the pages of the secure documents, a geo-positioning manager 425 for creating and managing the templates that are used to create the scrambled security codes and printing them on the secure documents, a print lock manager 430 for managing printing of the secure document copies, an encryption manager 435 for creating and managing encryption and decryption keys, a communications adapter manager 440 for managing connectivity with computing apparatuses 360, a User Interface (UI) 445 for interacting with an operator of server 310, a print manager 450 for printing secure document at printers 320, 325, an e-signature manager 455 for managing electronic signatures embedded in the secure documents, a database manager 460 for managing the archiving of secure documents, security codes, account and document data, and any other information related to a secure document or its oner, an invoicing manager 470 for managing invoices for the services bought by the user, a dispatch manager 475 for managing the dispatch of secure documents to the use who ordered their printing by server 310, a memory 485, and a processing module 480 for managing all the other modules and optionally for creating a secure document electronic file, associating the secure document with at least one parameter, generating a Quick Response (QR) code for each page of the secure document, generating at least one security code for each page of the secure document, generating a geolocation template for each page of the secure document, generating at least one timestamp for each page of the secure document, embedding the at least one encrypted security code, and the at least one timestamp in each page of the secure document electronic file using the geolocation template, embedding each QR code in a page of the security document electronic file, archiving the secure document electronic file and the geolocation template, and transmitting the secure document electronic file and the geolocation template to a computing apparatus.

[0082] Computing apparatus 490 is used by a user to connect to server 400 and to print, locally, the secure document. Computing apparatus 490 has a UI module 493, a memory 494, a communications adapter manager module 495, and a processor module 493 for managing all other modules. Additional modules may also be present, or some of the presented modules of the computing apparatus 400 may be omitted or combined, as apparent to a person skilled in related art. [0083] Creating and sending a secure document

[0084] FIG.5 shown an example use case for creating and sending a secure document. Use case 500 starts with a user connecting 510 to the server, and creating a user account 520 (e.g., a personal account or a corporate account) if one such account does not already exist. If the user already has an account at the server, or after he creates the account, the user logs in to the account using his credentials. Having logged in his account, the user may select an existing project, or create a new project 530 and enter one or more attributes. The server associates these attributes with the project. By means of example, the attributes may include a project name, document name(s), project and document categories, status, company or person owning the project and files, document editors, etc.). A project may be the equivalent of a folder containing several secure documents and is suitable for new documents to be created or uploaded for archiving and management. Having created the project and/or set its document attributes, the server creates a set of empty secure document placeholders and associates them with the project 535.

[0085] The user may select any secure document placeholder and enter the number of pages, signature pages and any other attribute 540 relating to the selected document placeholder. The server, uses these attributes to generate the secure document, generate 545 a QR code, one or more security codes, one or more timestamps, a print-count flag (to enable a single copy or more copies of the security document to be printed), a filed for setting the person or entity allowed to print the document, and a geolocation template for printing the security codes on the print copy of the secure document using geo-positioning on the document page. All the previous security features, or a subset thereof, may be created for each page of the secure document, so that each page of the security document has a unique set of associated security features that are used for authenticating and for regulating the dissemination and printing of the secure document. These security features are then encrypted and embedded in the digital (i.e., archived version of the secure document). The dissemination and printing of the secure document may be enforced with a combination of encryption and decryption keys, One-Time-Passwords (OTP), etc. [0086] Having created the secure document and embedded the security features in the document, the user may enter a document description 550. The user then enters the content of the document (e.g. by typing a contract, editing a lottery ticket with text and graphics, creating a bond template, etc.) or imports a non-secure document, text or graphics files that contain the desired content of the secure document. To import such source content, the user may use any standard UI offered by the server (e.g. file select from a list, drag-n-drop file, etc.) 560. He may also edit the imported document content to create the desired secure document layout and add or remove fields, like adding an e- signature field, or other. Such fields are optional and are applicable to different types of documents based on the type of document. For example, a digital signature field is needed in a secure contract but not in a secure lottery ticket.

[0087] The user may then electronically sign the secure document 570, if the document requires his signature. The electronic signature may be implemented by software and/or hardware forming part of the server, or in alternative implementations, the server contacts an external electronic signature server and consumes electronic signature services offered by the electronic signature server. Any type of electronic signature server, or protocol may be used.

[0088] The secure document is then archived 580 at the server or at a database or database server connected to the server and the secure document is then, optionally, sent 590 to the user or to a recipient requested by the user.

[0089] Printing a secure document

[0090] FIG.6 shows an example use case for printing a secure document. Use case 600 starts with a user receiving a secure document file 610, e.g. by e-mail, by downloading the secure document file from the server, or via any other means suitable for transferring an electronic file. The user sends the document (i.e., text and graphics) to an ordinary printer 620 for printing the front pages of the secure document using regular ink, visible in daylight. The printer prints on the back pages of the secure document the corresponding QR codes 630 and the user feeds the same printed sheets to a security printer for printing at the back pages the security codes 640, according to the geo- localization template, using UV-sensitive ink.

[0091] Printing is allowed only once, so that a single copy of the electronic document is printed. This is achieved by using the print-count flag, which is encrypted and cannot be tampered with or changed by document processors, only reset by administration level processors with administration rights, in the event there is a printer related error. This prevents more than one copy of any document to be duplicated. Multiple copy document sets must have separate security codes entered for each copy, to prevent future duplication or alteration. [0092] The printing information (e.g. printer used, person/entity that printed the secure document, timestamps, etc.) is automatically sent by the security printer (or by the software used to print at the security printer) to the server 643. The server, then updates 646 the security codes and timestamps that are embedded in the original copy of the secure document it has archived.

[0093] If the user or other recipient of the document wishes to print the document again, he needs to contact the server 660, and request a new secure document copy for printing. If this allowed by the document owner, or by a policy used to resolve such situations, the server updates the security codes 670 and the print-count flag 680 of the electronic document to allow the document to be printed again by its processor, archives the edited secure document 690 and sends a copy 695 to the recipient.

[0094] Amending a secure document

[0095] FIG.7 shows an example use case for updating a secure document. Use case 700 starts with a user connecting 710 at the server, selecting a project and a document from the list of documents in the project 720, and amending the document 730.

[0096] After the user has finalized the amended secure document, the server updates the security features 740 of the secure document, i.e., some or all of the security codes, QR codes, geolocation template, print-count flag, etc., and archives the amended secure document 750.

[0097] A special case of amendment is the electronic signing of the secure document, which can be performed by any recipient authorized to sign the document, and which is controlled by the security features of the secure document.
