Unimodal biometrics uses the single source of physiological/biological characteristics (e.g. face, fingerprint, online signature, DNA) for person authentication. So, if any issue persists in the person’s physiological/biological traits then the system leads to serious issue. To overcome this issue, we move into the Multimodal biometrics. Multimodal biometrics is the integration of two or more types of biometrics (e.g. Fingerprint and Face, Face and Iris, Iris and Fingerprint).In Multi biometrics the noise in any one of the biometrics will lead to high false reject rate (FRR) while identification. If any multi biometrics failure means, we can use another type of multi biometrics. To keep the biometric template as secure we use the soft computing technique i.e. Fuzzy Logic. The proposed work is to enhance the security in ATM system with multimodal biometrics along with email verification code which provides two level securities to the system.
