Answer : Advantages of Biometrics In biometrics technology, a person can be uniquely identified on the basis of measurement of physical constitution and behavioral characteristics. Biometrics technology is used in computer controlled security systems. In this case, the human biological data is stored in the computer database and then these data are automatically matched. If the data match is found, the validity of the person is confirmed. In computer science, biometrics is used as a technique for identifying individuals and controlling access to a corner system. This method allows users to access any program , system or cell on biometrics devices . This maintains the security and confidentiality of the system. Again with the help of biometrics technology the exact access of the assumed person can be controlled. Biometrics methods are also used to distinguish someone from a group of suspects. Thus , biometrics technology plays an important role in security.
