Abstract
The unique parts of body that identifies a person are known as biometrics. The different biometrics used now-a-days are fingerprints, iris, face recognition, handwriting, gesture, retina, ear height etc. The biometrics when used in conjunction for the identification or verification of an individual are called as MULTIMODAL BIOMETRICS. This is assumed to be a better approach for security. It overcomes some of the limitations of single biometrics as this approach is more reliable. ID cards, Access cards, Punch, PIN, USER ID, passwords are used for identification but ID cards can be stolen or can be lost and user id s and passwords can be forgotten. So biometrics overcomes all these and has become the emerging trend. Further the security of the database is improved using cryptosystem. It takes a key and changes plain text into cipher text and back.
