Abstract

A method performs biometric verifications to authenticate the identification of users using a central biometric authority (CBA). This allows parties to an electronic transaction to be assured of each other'"'"'s identity. Specifically, at the sender side, a first message to a receiver is generated, wherein the first message includes a message text and a unique message identifier (UMI). At the sender side, a second message concerning a posting to the CBA is also generated, wherein the second message includes the sender'"'"'s biometric sample, the UMI, and the sender'"'"'s submission profile record. At a receiver side, it is decided that if a receiver wishes to verify the sender'"'"'s identity and if so, the first message is automatically verified. At the receiver side, a third message concerning a receiver'"'"'s posting to the CBA is issued, the third message including only the UMI, as received from the sender side. Finally, at the CBA, a reply to the third message is provided, the reply including the sender'"'"'s verification result.

Claims

1-11. -11. (canceled)

12. A method for verifying the identity of one or more parties to a transaction using biometrics, whereby a third party biometric authority (CBA) stores biometric templates for the one or more parties in a database, and performs the identity verification upon receiving one or more messages including biometric sample data for the one or more parties.

13. The method of claim 12, wherein a point of transaction (POT) operator verifies the identity of an authorized transactor (AT) by transmitting a message to the CBA including biometric sample data for the AT.
