Patent ID: 8458465

Claim:
A method for biometric authentication, the method comprising: storing in memory a biometric template; receiving biometric data associated with a user; comparing, by a processor, the biometric template to the biometric data; retrieving from the memory a phrase from a prior communication of the user; comparing speech data generated by a microphone with a speech verification template retrieved from the biometric template, wherein the speech data is indicative of the user speaking the phrase; determining a degree of a match between the speech data and the speech verification template; determining the degree of the match between the biometric data and the biometric template, wherein the biometric data pertains to biometric information other than the speech data; forming a response based on the degree of the match between the speech data and the speech verification template and further based on the degree of the match between the biometric data and the biometric template; determining an age of the biometric data exceeds a recency threshold; and generating a notification when the age of the biometric data exceeds the recency threshold; wherein the biometric template is organized according to a plurality of group identities and individual identifies; wherein each group identity in the plurality of group identities is associated with a subset of the individual identities; wherein the individual identities correspond to biometric records; wherein one of the biometric records includes a name of a biometric data file containing the biometric data, a name of a biometric template file containing the biometric template, and a time stamp; and wherein the timestamp indicates the age of the biometric data.
