Security is a very important aspect in the biometric system. There are number attacks and there remedial solutions discussed in the literature on different modules of biometrics system and communication links among them. But still the researchers are not able to secure every module of a biometric system against these attacks. Template and database are the very important parts of biometric systems and attacker mostly attack on template and database of biometric system so securing them is a very crucial issue these days. In this research paper our focus is on template and data base security in biometrics system and we develop a system to encrypt and decrypt the biometric image using helper data of a fingerprint and password to make it secure so that even if someone gains access to the encrypted image stored in the database he will not able to reproduce the original image from it and it will be useless for him.
