On enhancing biometric authentication with data protection

This paper describes a method for biometric identification based user authentication in distributed environments, which makes use of trusted computing platforms (CPs) combined with smart cards (SCs) and trusted biometric readers (BRs) for protection of biometric data. With this authentication method, a user can establish a trust relationship with an accessed CP, and the user can trust that the CP will not disclose his/her sensitive biometric information to any unauthorised entity.
