Biometric Technology

Biometric is a security mechanism used for authentication and providing access to an individual based on verification of one’s physical characteristics which are pre-stored in a biometric security system or scanner. It is able to recognize a person on the basis of the unique features of their face, fingerprint, signature, DNA or iris pattern and then impart a secure and convenient method for authentication purposes. The basic premise of biometric authentication is that every person is unique and each individual can be identified by his or her intrinsic or behaviour traits.

The biometric servers usually require very less database memory, as the templates use small storage. Easiness of use is major benefit over password based authentication. People in general find fingerprint, retina and voice scanning an easy option for authentication. Biometrics are stable and enduring, which means it changes very little over the course of one’s life and can identify a person in spite of little variation over time.
