The cryptographic algorithms in current use are facing the problem of maintaining the secrecy of private keys which need to be stored securely to prevent forgery and loss of privacy. Stored private keys are saved by user chosen passwords are often acquired by brute-force attacks. Also, the user finds it difficult to remember large keys. So, it is a major issue in asymmetric cryptography to remember, protect, and manage private keys. The generation of cryptographic key from individual user’s biometric feature is a solution to this problem. In this approach, it is too hard for the attacker to guess the cryptographic key without the prior knowledge of the user’s biometrics. But the problem with biometrics is that compromise makes it unusable. To solve the above issue, cancellable biometrics has been proposed. In this present work, there is an attempt to generate cryptographic key from the user’s cancellable fingerprint …
