Cancellable Biometrics

In “conventional” biometric systems, there are many situations where it is important to consider security and privacy issues. For example, biometric-related information is not secretly stored or transmitted, which implies that compromise of biometric information would lead to unauthorized access and information misuse, and the enrolled biometric data are not revocable, which implies that compromise of biometric data will result in permanent lost of biometric traits. Since the biometric data are permanently associated with a user and the biometric resources of a user are limited, the legitimate user would not be able to regenerate another set of valid biometric identifiers. The security and privacy of biometric data have gained tremendous interest among researchers; however, serious criticisms against the biometric technology have not been addressed satisfactorily. Thus, we devote a considerable amount of time to discuss the security and privacy of biometric data as well as the existing solutions to the problems in this chapter.
