Samsung has filed a patent Thursday for technology to provide users with hints for forgotten passwords based on palm scans, SamMobile reports.
The system described in the 42-page patent application involves the user enrolling an image of his or her palm, and then retrieving a password hint by taking a picture of his or her palm with the device’s rear camera. The device then adds the hint to the image in the form of the password characters scattered across the lines of the palm.
The abstract of the patent describes “a control unit for extracting biometric information of a user from an acquired image and acquiring a password hint on the basis of the biometric information and a preconfigured password.”
Samsung devices already offer iris scans, facial and fingerprint recognition, along with PINs and special patterns for security.
In October, Samsung registered for a patent for a pressure sensitive under-the-display fingerprint scanner.
