A Study of Changeable Biometrics for Fingerprint Recognition

To enhance security and privacy in biometric systems, changeable (or cancelable) biometric systems have been developed. These systems can revoke and re-issue biometric data when it is compromised. The proposed method generates changeable fingerprint templates by using a single reference point. In our experiments, performance the proposed method were evaluated and the experimental results showed that the proposed method is a useful way of constructing changeable biometric systems.
