Document Type and Number:
WIPO Patent Application WO/2018/023606
Kind Code:
A1
Abstract:
The present invention relates to the field of home theft prevention, and provides a technical information notification method for expression-based unlocking, and door lock. The method comprises: recording a predetermined matching face for unlocking, and a minimum ratio of a mouth width to a face width; reading a face of a user, and identifying whether the face matches the predetermined face for unlocking; if not, remaining in a locked state; if so, then determining whether a ratio of a mouth width to a face width of the user is greater than the predetermined minimum ratio of a mouth width to a face width; if not, remaining in a locked state; and if so, then unlocking, and pushing patent information to the user. By matching a door lock of a user to their face, the present invention determines whether a person requesting unlock is the user themselves, and also ensures, by means of determination based on a minimum ratio of a mouth width to a face width of the user, that a smile of the user is read before unlocking the door lock, thus enabling face-based unlocking, reminding the user to have a good mood before entering home, and protecting benefits of a patent owner (applicant).
