Apple patents fingerprint sensor

By
Apple has filed a patent application for a fingerprint sensor, suggesting the firm is planning to add biometric technology to future devices.

The move comes just months after the iPhone maker acquired mobile security firm AuthenTec, which holds an array of fingerprint recognition patents.

Apple's recent patent filing - detailed by Patently Apple - describes a hardware "window" that can become selectively "transparent or opaque", to reveal an "image capture device, a strobe flash, a biometric sensor, a light sensor, a proximity sensor, or a solar panel" as a means of unlocking a handset.

AuthenTec has developed a patented swipe sensor system that reads the live layer of skin beneath the actual fingerprint to make it accurate "for everyone every time".

In theory, this could enable users to unlock their devices by placing or swiping a single digit against the screen, and have specific commands mapped to another finger for one-touch execution.

Apple is yet to officially outline its plans for AuthenTec, but there were rumors that the iPhone 5 was to feature its biometric security ahead of its release.
