Abstract: The preservation of your identity could become a major concern. In many situations, you need to claim an identity and this claim needs to be verified somehow. The technology called biometrics may help. But, what if a deliberate impostor claims your identity? Will this forgery be always detected? Biometric identity verification is imperfect. This paper reviews some of the techniques that a deliberate impostor could use to defeat a biometric verification system. It focuses on audio-visual forgeries using voice conversion and face animation. It also describes identity disguise as a means of falsifying and concealing one|s identity. The recovery of an identity and cancellable biometrics are also useful techniques to protect from identity theft. Such techniques could also find useful applications in multimedia.

Keywords: identity verification; forgery; audio-visual imposture; voice conversion; face animation; identity disguise; identity recovery; cancellable biometrics; security; privacy.
