A Security API for Multimodal Multi-biometric Continuous Authentication

In order to enhance security, biometrics has increasingly become part of security architectures. Since some of uni-biometrics´ vulnerabilities have already been exploited, they have been replaced or enhanced by multi-biometrics. Also, continuous authentication processes have been considered an important security caution to raise systems reliability. In such a context, we propose the security API of an access control architecture that combines multi-biometrics and a continuous authentication process in order to accomplish a high security level. In addition, our API also supports the use of biometric template security mechanisms, which is a relevant concern since, unlike passwords, stolen biometric templates cannot be revoked. Aiming at the validation of what has been proposed, the API and a prototype application were implemented.
