Personal authentication systems based on biometrics have given rise to new problems and challenges related to the protection of personal data, issues of less concern in tradi-tional authentication systems. The irrevocability of biometric templates makes biometric systems very vulnerable to several attacks. In this paper we present a new approach for biometric template protection. Our objective is to build a non-invertible transformation, based on random projection, which meets the requirements of revocability, diversity, se-curity and performance. In this context, we use the chaotic behavior of logistic map to build the projection vectors using a methodology that makes the construction of the pro-jection matrix depend on the biometric template and its identity. The proposed approach ∗Corresponding author. 1 May 4, 2015 23:29 WSPC/INSTRUCTION FILE ws-ijai
