Faster secure computation for biometric identification using filtering
Julien Bringer, M. Favre, Hervé Chabanne, Alain Patey · 2012
Several attempts have been made to apply Secure Multiparty Computation (SMC) to the context of biometric recognition. Such constructions are very bandwidth and time-consuming. In order to reduce both consumptions, we propose a new construction for biometric identification based on filtering techniques that has the same security properties as the other SMC-based schemes but runs significantly faster while keeping good biometric performances. We propose as an example a secure iris identification algorithm with a fast filtering phase based on Hamming distance. We moreover present implementation results for this proposal that confirm our improvements.
