"In this paper, the authors address the issues of using edge detection techniques on facial images and to produce cancellable biometric templates. With increasing use of biometrics, there is a real threat for the conventional systems using face databases, which store images of users in raw and unaltered form. If compromised not only is it irrevocable, but can also be misused for cross-matching across different databases. So it is desirable to generate and store revocable templates for the same user in different applications to prevent cross-matching and to enhance security, while maintaining privacy and ethics."
