Indeed, it makes it possible to reduce certain unimodal biometric systems limitations, such as the impossibility of acquiring data from certain people or intentional fraud, while improving recognition performance. These benefits of multimodality to unimodal biometric systems are achieved by fusion of several biometric systems. In this case, the security is a necessity to have robust and user-friendly biometric systems. In this paper, we proposed a Revocable multi biometric scheme to secured multi biometric data, we focused our attention on BioHashing method which is a recent technique that can address simultaneously the invasion of privacy issue and the Security. An improvement in the level of characteristics has been introduced to obtain very satisfactory results. It combines fingerprint multi sensor features of a single human finger.
