We propose a biometrics-based(fingerprint)Encryption / Decryption Scheme, in which unique key is generated using partial portion of combined sender’s and receiver’s fingerprints. From this unique key a random sequence is generated, which is used as an asymmetric key for both Encryption and Decryption. Above unique Key is send by the sender after Watermaking it in sender’s fingerprint along with Encrypted Message. The computational requirement and network security features are addressed. Proposed system has a advantage that for public key, it has not to search from a database and security is maintained.
