A survey of distributed biometric authentication systems

Abstract

In ACISP'07, Bringer et al proposed a new approach for remote biometric based verification, which consists of a hybrid protocol that distributes the server side functionality in order to detach the biometric data storage from the service provider. Besides, a new security model is defined using the notions of Identity and Transaction Privacy, which guarantees the privacy of the identity-biometrics relationship under the assumption of non-colluding servers. In this survey, we review the scheme of Bringer et al and the following biometric verification systems that improve upon it in terms of computation and communication complexity. In this context, we discuss about the recent result of Sarier, which describes a secure and efficient multi-factor authentication scheme with a different biometric storage method that results in reduced computation and database storage cost.
