The present invention relates to a method and a device of verifying the validity a digital signature based on biometric data. A basic idea of the invention is that a verifier attains a first biometric template of the individual to be verified, for instance by having the individual provide her fingerprint via an appropriate sensor device. Then, the verifier receives a digital signature and a second biometric template. The verifier then verifies the digital signature by means of using either the first or the second biometric template as a public key. The attained (first) biometric template of the individual is compared with the received (second) biometric template associated with the signature and if a match occurs, the verifier can be confident that the digital signature and the associated (second) biometric template have not been manipulated by an attacker for impersonation purposes.
