Biometric systems are used for identification of users based on their physical characteristics. Proof of the authenticity of the user in a biometric way process in two stages. In the first phase the device scans the user data and record them in a list. The unique individual characteristics are extracted and converted into templates which are recorded as encrypted digital data. In the second phase, the user again goes through the scanning process, the outcome of which is compared with patterns from the database. Thus he receives or gains access. Organizations for which security is a priority, would be useful to note that it is much harder to lie one biometric system.
