Managing private credentials by privacy-preserving biometrics

Abstract

We investigate in this paper the need to managing a user’s private credentials using privacy-preserving biometrics, define several private credential management work models under different trust models between a user and an external party. A general pipeline using privacy preserving biometrics for private credential management is proposed to achieve the purpose of biometric template protection, biometric-secret binding, and biometric recognition accuracy performance improvement. The proposed scheme was implemented and tested in the European CIP project PIDaaS, and demonstrated advantages in privacy preservation and accuracy performance preservation.
