Authentication protocol using fuzzy eigenface vault based on MoC

Abstract

In this paper, the eigenface-based fuzzy vault scheme, called a fuzzy eigenface vault, is designed and examined, and authentication protocol using the fuzzy eigenface vault is designed based on a smartcard and analyzed security of the proposed authentication protocol. Especially, face recognition for user authentication has several advantages such as natural, nonintrusive, convenience, and easy to use. However, it is difficult to apply biometrics on cryptographic security because of different images in each acquisition phase. Furthermore face data can be vulnerable to modification attack and illegally let out. From that, the need of secure biometrics authentication methods has been increased and we propose a new authentication protocol using fuzzy eigenface vault and smart card. The proposed protocol has three advantages compared to previous works. First, to get security, accuracy and convenience without reluctance at same time, we use eigenface in a fuzzy vault scheme which is suitable to combine biometric authentication and cryptography. Second, to enhance security, secret data which is for construction of the fuzzy eigenface vault is saved on a smart card. Third, to reduce a transmission-based attack, a transmission of message is occurred just one time in a login phase.
