Abstract:
1. A biometric method of authenticating the identity of an individual employing a preselected sequence of linear partial fingerprint signatures comprising the steps of: (a) obtaining a reference set of linear partial fingerprint signatures and a total scan time measurement associated with each linear signature in said reference set, and storing an electronic representation of the reference set and their associated total scan times in a comparison means, said reference set derived from two or more scans taken across predetermined paths on an individual's fingerprint; (b) generating a candidate set of linear partial fingerprint signatures and a total scan time measurement associated with each linear signature in said candidate set, and applying an electronic representation of the candidate set and their associated total scan times to a comparison means, said candidate set derived from at least two scans taken across correspondingly predetermined paths on that individual's fingerprint, the particular two of said at least two scans and the sequence of their application to said comparison means being selected so as to serve as a personal code; and (c) providing said comparison means for comparing each of said linear signatures of said reference set with each of the corresponding linear signatures of said candidate set based on conforming the total scan times of corresponding linear signatures, and for providing an affirmative response for a successful comparison and a negative response for an unsuccessful comparison.
