Biometrics in claim-based authentication framework


Nowadays biometric authentication and identification becomes a part of every-day life. As a result, many services emerge that rely on biometric-based access control. However, from a user point of view, supplying biometric information to many different service providers imposes high privacy and security risks. In this paper we focus on the use of biometrics in a claimed-based authentication framework. The frameworks allows for a limited number of identity providers, thus overcoming the need to supply biometric data to multiple untrustworthy service provides. We argue that in this case we can deploy the information-theoretic framework for privacy-preserving biometric systems for joint authentication and identification studied in Willems and Ignatenko [2010].
