System and method for distorting a biometric for transactions with enhanced security and privacy

Image Number 10 for United States Patent #6836554.

Authentication methods are very important in several applications. Existing methods of authentication based on possessions or knowledge have several problems that can be overcome by using biometrics. Unfortunately biometrics-based authentication is unrevocable today and has many privacy concerns in users' minds. The proposed technique employs signal scrambling and morphing techniques to intentionally distort the original biometrics signal in a non-invertible fashion. If the security is compromised, the system can cancel a particular distortion and reacquire the signal with a new distortion function. This provides functionality as good as non-biometric authentication methods in terms of their power of revocation.
