Image Recognition
In one embodiment the patent explains how the technology would detect the presence of the user’s palm and project dot images onto its surface in order to capture image data that could then be used to perform biometric authentication “based upon comparing determined palm vein data and stored palm vein data”. “An electronic device may include a display layer including light transmissive portions and non-transmissive portions,” the patent explains. “The electronic device may also include a palm biometric image sensor layer beneath the display layer and configured to sense an image of a user’s palm positioned above the display layer based upon light reflected from the user’s palm passing through the light transmissive portions of the display layer. “The electronic device may further include a controller configured to capture image data from the user’s palm in cooperation with the palm biometric image sensor layer and determine a surface distortion of the user’s palm based upon the image data. “The controller may also be configured to perform a biometric authentication of the user’s palm based upon the image data and the surface distortion.”The US Patent and Trademark Office granted Apple a patent for a biometric sensing system to bring Touch ID to Apple Watch in July 2022.
