HTC Was Granted The Face Unlock Patent

Recently, the US Patent and Trademark Office granted HTC the patent describing FaceUnlock features. It details "a method for unlocking a locked computing device including obtaining biometric information."

Details of the patent are related to the way a device can compare this biometric information to a predetermined requirement in order decide if it needs to maintain the locked status or to unlock.

The integrated sensor is used to capture the facial profile and to match it to the predetermined profile. The Android community is familiar with FaceUnlock features since the release of Ice Cream Sandwich.

High profile players on this market, like Samsung, have already integrated this feature in the latest update. Samsung i9000 Galaxy S and the Samsung i8150 Galaxy W owners, for instance, can make use of FaceUnlock.

HTC's new patent also includes fingerprint matching among the biometric requirements that are needed to authorise a device unlock. This was also a feature unveiled at last year's edition of CES by Motorola's Atrix 4G.

Analysts are already sensing a new legal war over patent infringements, with so many parties interested in Face Unlock functionality.
