Abstract :
In this paper, we present the first biometric identity based signature (BIO-IBS) scheme that is fully secure in the standard model. We use biometric information as the identity and construct the user´s public key by using a fuzzy extractor. A biometric reading provided by the alleged signer would be enough to verify the signature. The scheme was proven fully secure based on well-exploited q-Strong Diffie-Hellman computational problem. However, a biometric identity based signature scheme that is fully secure in the standard model has not been proposed before.
