Abstract:
1. A method for preventing false acceptance of latent biometric information, comprising: sensing first biometric information from a first portion of a biometric information source; sensing second biometric information from a second portion of the biometric information source, each of the first and second portions including an overlapping same portion of the biometric information source, the first and second biometric information received at a different time one from the other; analyzing the first biometric information and/or second biometric information to identify a feature within the overlapping same portion for determining a reference frame for use in characterizing the first biometric information and/or the second biometric information; determining first data relating to the feature within the first biometric information and determining second data relating to the same feature within the second biometric information; comparing the first and second data to detect a difference between the first and second biometric information; and determining the biometric information source as a live biometric information source in dependence upon the detected difference, wherein the detected difference is indicative of relative motion of or about the feature within a local reference frame.
