One of the features that Ice Cream Sandwich brought to Android and the Galaxy Nexus was Face Unlock. Although not very secure, it did provide a fun, additional method to unlocking the phone. In a curious turn of events, it turns out HTC has been granted the patent behind the technology, which certainly raises some legal questions.
HTC’s patent details “a method for unlocking a locked device”, which could be a smartphone or tablet, with biometric information. In this case, that information can include an image of a person’s face, although fingerprints are also covered.
