<p>A system and method of authenticating users and data. One embodiment of the invention includes a smart card (100) that digitally signs a message in response to authenticating biometric information that is provided by a user. The smart card (100) may include a random number generator (204) and an encryption module (208). In an enrollment mode, the biometric data analyzer (200) receives biometric data (216) from a user and triggers the random number generator (204) to create a public key (220) and a private key (224). The private key (224) is stored in a tamper-resistant component on the smart card (100). The public key (220) is transmitted to an external device, such as a computer, via a card reader interface (130). During a signing mode, the smart card (100) digitally signs incoming messages subsequent to verifying the biometric information (216) that is provided by the user.</p> |
