Here we are going to achieve secure for the finger print images by using symmetric method. This symmetric finger print image encryption is a combination of scrambling and confusion process. It also include the chaotic map in which scrambling will be used to identify address of the finger print image pixels, and bit -level permutation is used for confusion process so it will enhance the security. Encryption scheme possesses large key space to resist brute force attack, malicious attack like cropping, noising and possesses good statistical properties to frustrate statistical analysis attacks
