Abstract:
1. For an electronic signature device comprising a processor, a memory, a user input device including a first biometric input device, and a device interface, all communicatively connected by at least one bus, a method of personalizing the electronic signature device to a user, comprising: receiving a digitized biometric signature of the user via the first biometric input device; generating a cryptographic key according to a predetermined cryptographic scheme; generating a biometric electronic template based on said digitized biometric signature; and storing said cryptographic key and said biometric electronic template in the memory; wherein generating cryptographic keys includes generating a prime parameter, a sub-prime parameter, and a base parameter; generating a signing private key; generating a signing public key based on said prime, sub-prime, and base parameters; and generating a user public key based on said signing private key and said prime and base parameters; and further comprising storing said prime, sub-prime, and base parameters, and said signing private and public keys in the memory.
