Biometrics relates to the use of physiology and/or behaviour to determine or verify the identity of individuals. Despite the advantages of these biometric systems over traditional authentication systems that use passwords and ID cards, they are still vulnerable to specific limitations that can significantly degrade their functionality. The confidentiality of biometric data must be protected to ensure the privacy of users, while security mechanisms are necessary to ensure this protection. The

Unfortunately, even well-established multi-biometric systems suffer from vulnerabilities, the most crucial elements being the biometric models that store the user's biometric data. If a user's biometrics is compromised, a person's identity and privacy are also compromised, since it is impossible to revoke or reissue the biometric template. Therefore, secure and revocable multi-biometric templates protection schemes are required to ensure multi-biometric system integrity and user privacy. This article presents a revocable multi-biometric scheme to secure multi-biometric data and focusses on the BioHashing method which is a recent technique capable of addressing the reversal of the confidentiality and security problem.
