To verify identity of person his /her physical or behavioural characteristics can be use,this strategy is called as Biometrics. Preservation of privacy of digital biometric data such as iris,face images etc. which stored in central database becomes more essential. This paper introduced the new visual cryptographic technique that allows encryption of visual information such that decryption can perform using human visual system hence cryptography computation does not required any extra hardware and software. In visual cryptography secrete image is encrypted into number of shares which independently can not reveal information about original image. For getting information about original image all sheets must be available simultaneously.
