Abstract
The wide diffusion of biometric based authentication systems, which has been witnessed in the last few years, has raised the need to protect both the security and the privacy of the employed biometric templates. In fact, unlike passwords or tokens, biometric traits cannot be revoked or reissued and, if compromised, they can disclose unique information about the user’s identity. Moreover, since biometrics represent personal information, they can be used to acquire data which can be used to discriminate people because of religion, health, sex, gender, personal attitudes, and so forth. In this chapter, the privacy requirements, the major threats to privacy, and the best practices to employ in order to deploy privacy sympathetic systems, are discussed within the biometric framework. An overview of state of the art on privacy enhancing technologies, applied to biometric based authentication systems, is presented.
