METHOD AND SYSTEM FOR BIOMETRIC AUTHENTICATION
First Claim
1. A method of text-based biometric authentication comprising:
- capturing biometric data for a desired biometric type from an individual at a client system and communicating the captured biometric data to a server system;
determining an algorithm for converting the biometric data into authentication words;
converting the captured biometric data into authentication words in accordance with the determined algorithm, the authentication words being combinable into a sentence that represents a plurality of different biometric types;
comparing the sentence against a gallery of identity records stored in the server system, each of the identity records including enrollment biometric words of a corresponding individual;
identifying at least one of the identity records as a potential matching identity record when at least part of the sentence matches at least one of the enrollment biometric words included in the at least one identity record; and
generating a list of potential matching identity records.

Abstract
A method of authentication is provided that includes capturing biometric data for a desired biometric type from an individual, determining an algorithm for converting the biometric data into authentication words, converting the captured biometric data into authentication words in accordance with the determined algorithm, including the authentication words in a probe, and comparing the probe against identity records stored in a server system. Each of the identity records includes enrollment biometric words of an individual obtained during enrollment. Moreover, the method includes identifying at least one of the identity records as a potential matching identity record when at least one of the authentication words included in the probe matches at least one of the enrollment biometric words included in the at least one identity record, and generating a list of potential matching identity records.

11. A system for text-based biometric authentication comprising:
-
a computer configured as a server, said server including at least a data base, said server being configured to store within said database at least one conversion algorithm and at least a gallery of data comprising identity records, each identity record including at least biographic data of an individual and enrollment biometric words of the individual, the enrollment biometric words being generated from a desired biometric type and from biometric types different than the desired biometric type; and at least one client system comprising at least a computer configured to communicate with said server, said client system being configured to at least capture biometric data for the desired biometric type from an individual, said server being further configured to convert the captured biometric data into authentication words by executing the at least one conversion algorithm, the authentication words being combinable into a sentence, compare the sentence against the gallery, identify at least one of the identity records as a matching identity record when at least a part of the sentence matches at least one of the enrollment biometric words included in the at least one identity record, and generate a list of potential matching identity records. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A computer program recorded on a non-transitory computer-readable recording medium included in an authentication computer system for enabling authentication of individuals, the computer program being comprised of instructions, which when read and executed by the authentication computer system, cause the authentication computer system to perform at least the following operations:
-
determine a plurality of algorithms, each of the algorithms being operable to convert captured biometric data of a corresponding biometric type into a vocabulary of words; convert the captured biometric data for each biometric type into authentication words in accordance with the corresponding one of the algorithms, the authentication words being combinable into sentences; compare a sentence against identity records, the sentence includes authentication words associated with an individual and each of the identity records includes enrollment biometric words of a corresponding individual; identify at least one of the identity records as a potential matching identity record when at least part of the sentence matches at least one of the enrollment biometric words included in the at least one identity record; and generating a list of potential matching identity records. - View Dependent Claims (20)
