Abstract: Template preservation is one of the major issues in biometric authentication systems. Stored templates during enrollment are subjected to different types of intrusion attacks. The stored templates can be revoked or reissued by intruders using spoofing techniques. To overcome these issues multimodal biometrics are used to authenticate a user rather using single biometric template. A multimodal biometric system uses two or more biometrics to authenticate a user. Unique and effective biometrics obtained from a single individual are fused together to obtain a single template. Feature transformation or biometric cryptosystems can be used to protect the templates from compromises. So, this work proposes a fuzzy vault technique to preserve the multimodal biometric templates from any sort of compromises or attacks. False acceptance rate(FAR) and Genuine acceptance rate (GAR) can be used to evaluate the system
