What is biometrics and how can I used it?

Biometrics involves using the different parts of the body, such as the fingerprint or the voice, as a password or form of ID. The Federal Agents use the fingerprints from a crime scene to find a criminal. Biometrics will use the finger print to validate the individual, much like the Federal Agent will do with possible suspects. Biometrics is becoming more public. Iris scans are being used in places like the United Kingdom ATM machine's instead of the normal codes.

Most biometric systems work in a similar manner. First, a person is enrolled into a database using the specified method. Information about a certain characteristic or trait of the human is captured. This information is usually placed through an algorithm that turns the information into a code that is stored in a database. When the person needs to be identified, the system will take the information about the person again, translates this new information with the algorithm, and then compares the new code with the ones in the database to discover a match, and there you have biometrics.
