Abstract:
An object authentication system for use in a secured environment for verifying an object having a nonpredictable plasticity in order to detect a counterfeit fingerprint, said system including:a remote site for selectively allowing access to said secured environment and including:a detector for generating real time image data of an applied object;an access mechanism responsive to a verification signal to provide access to said secured environment; anda local site disposed from said secured environment and coupled in signal communication to said remote site, said local site includinga processor for extracting from said image data real time topographical minutia points and measuring at least one real time physical relationship between said real time minutia points;a database memory for storing a historical image file corresponding to said applied object, said historical image file comprising respective statistical representations of respective spatial relationships between said minutia points, said statistical representations acquired through repeated detection and statistical analysis of said applied object; anda comparator for comparing said real time physical relationship to said statistical representations of said object and operativeto verify said applied object as matching said statistical representations where said real time physical relationship is within a predetermined minimum deviation from said statistical representations andto further verify said applied object in order to determine whether said applied object is a counterfeit, said applied object being authentic where said real time physical relationship is greater than zero and not greater than a predetermined maximum deviation from said statistical representations.
