Protection of Fused Template Using Visual Cryptography

Template protection is a challenging task in the field of biometric systems. Multimodal biometrics is an emergent technology in this field because of its high security features. In this paper, a novel approach is proposed to secure fused template of Iris and Finger Knuckle Print (FKP) by using visual cryptography. Visual cryptography is a secret sharing scheme where a fused template is encrypted into the number of shares, which independently disclose no information about the original fused template. The experimental work in the proposed work shows the efficiency of visual cryptography for securing fused template.
