Abstract
A digital signature system includes a first and second signature generation apparatuses. The second signature generation apparatus receives a first parameter generated using at least first biometric information to stores the first parameter in a storage. The first signature generation apparatus generates a second parameter using at least second biometric information for transmission to the second signature generation apparatus, which generates a second signature for a message to be signed using the first parameter and the second parameter for transmission to the first signature generation apparatus. The first signature generation apparatus generates a first signature for the message based on at least the second signature and outputs the first signature.
