The combination of cryptography and biometrics so as to enhance the security is called biometric cryptosystem. Misuse of biometric data or template can be avoided by using cryptosystem. In order to prevail over these problems like non universality, uniqueness and less accuracy which is generally seen in unimodal biometric system, multi-biometrics seems to be more accurate and reliable. Multi biometric system means using more than one trait (e.g. fingerprint, iris, face, palm print etc.). This system increases security and even matching performance which in turn increases accuracy rate.
