Patent ID: 8914645

Claim:
A method, comprising: receiving, by a centralized computer, personal information for a first person from a source, wherein the personal information for the first person includes first historical biometric information; receiving, by the centralized computer, a request to authenticate a person, wherein the request to authenticate includes second biometric information; comparing, by the centralized computer, the second biometric information with the first historical biometric information; determining, by the centralized computer, a similarity measure based on the comparison of the second biometric information with the first historical biometric information; and determining, by the centralized computer, whether to authenticate the person and whether the first and second biometric information is trusted biometric information based on the similarity measure, wherein the determination of whether to authenticate the person and whether the first and second biometric information is trusted biometric information is based on the similarity measure and an amount of time between when the first historical biometric was captured and when the received second biometric information was captured, and wherein the determination of whether to authenticate the person and whether the first and second biometric information is trusted biometric information comprises comparing, by the centralized computer, the determined similarity measure to a similarity measure threshold, wherein the similarity measure threshold is adjusted based on the amount of time between when the first historical biometric was captured and when the received second biometric information was captured.
