A binary tree authentication scheme based on multi-biometrics

Aiming at practical requirements of the access control system, of which stable capability must be guaranteed, a binary tree authentication scheme based on multi-biometrics is proposed. It mainly includes three modules: one is a fingerprint identification module based on fuzzy vault, which can use the chaff points that are added into fuzzy vault to conceal the real points well and makes it difficult for illegal users to collect the effective information of fingerprint from the module; another one is a dynamic face recognition module, which selects an action randomly and prompts a user to finish this action and can resist the counterfeit attack from the photos, videos and 3D models effectively; the last one is finger vein recognition module, which has high level of security. Capability analysis shows that this scheme can not only insure the security, acceptability, convenience and accuracy, but also put an end to the phenomenon that biological recognition lack strong stability.
