Use Of Biometric Security

Biometrics is an essential part of the IT security certification course and is used for identification purpose and also for verification.Both of these can be illustrated as:

• Identification: Identification is determining who a person is.It involves trying to find a match for a person's biometric data in a database containing records of people and that characteristic.This method requires time and a large amount of processing power,especially if the database is very large.

• Verification: Verification is determining if a person is who they say they are.It involves comparing a users biometric data to the previously recorded data for that person to ensure that this is the same person.This method requires less processing power and time,and is used for access control(to buildings or data).
