Method and apparatus for access point control using digital encoding of images of skin-covered body parts

摘要

Methods and apparatus operative to control a state of an access point. The apparatus includes a biometric module adapted to acquire an image of a skin-covered body part submitted thereto and a processing module adapted for producing, responsive to acquisition of an image by the biometric module, a candidate code based on geometric measures of respective combinations of pixels taken from a plurality of subsets of like-shaded pixels in the image. The processing module is further adapted for causing a comparison to be performed between the candidate code and a set of references codes and, responsive to receipt of a signal indicative of the comparison yielding a match between the candidate code and one of the reference codes, sending a release signal to a restraint mechanism to cause the restraint mechanism to release the access point.
