Identification card verification system

A system for verifying the identity of a predetermined individual who is a member of a first set of individuals, said system comprising:

• a) master set apparatus acquiring an image of each individual member of a second set of individuals, said second set not including said predetermined individual as a member, and generating therefrom, by means of a first algorithm, a master set of principal component image signatures;
• b) enrollment apparatus having a copy of said master set in a first computer memory, said enrollment apparatus
• acquiring an enrollee image of the predetermined individual,
• generating, by means of a second algorithm, from said image of the predetermined individual and said master set, a set of identification parameters, and
• storing said set of identification parameters in an escort memory;
• c) verification station apparatus, having a copy of said master set in a second computer memory, said verification station apparatus
• reading said stored set of identification parameters from said escort memory,
• constructing, by means of a third algorithm, from said set of identification parameters and said master set, an image corresponding to the predetermined individual, and displaying said image.

A method of verifying a predetermined person's identity comprising the steps of

• a) acquiring an image of a characteristic feature from each of a group of individuals, said group of individuals not containing said predetermined person as a member, and constructing a master set of principal component feature signatures from said images by means of a first algorithm;
• b) acquiring an image of said predetermined person,
• c) creating from said image of said predetermined person and said master set, by means of a second algorithm, a set of identification parameters;
• d) storing said set of identification parameters in an escort memory;
• e) reading, from said escort memory at a verification station, said set of identification parameters;
• f) acquiring, at said verification station, a second image of said predetermined person, and constructing from said second image of said predetermined person and said master set by means of said second algorithm a set of verification parameters;
• and
• g) comparing, by means of a third algorithm, said verification and said identification parameters, and verifying the predetermined person's identity if the identification parameters differ from the verification parameters by less than a predetermined amount.

• f) constructing, by means of a third algorithm, from said identification set and said master set, a verification image;
• and
• g) displaying said verification image.
