What are the advantages of biometric systems for authentication?
Advancing automation and the development of new technological systems, such as the internet and cellular phones, have led users to more frequent use of technical means rather than human beings in receiving authentication. Personal identification has taken the form of secret passwords and PINs. Everyday examples requiring a password include the ATM, the cellular phone, or internet access on a personal computer. In order that a password cannot be guessed, it should be as long as possible, not appear in a dictionary, and include symbols such as +, -, %, or #. Moreover, for security purposes, a password should never be written down, never be given to another person, and should be changed at least every three months. When one considers that many people today need up to 30 passwords, most of which are rarely used, and that the expense and annoyance of a forgotten password is enormous, it is clear that users are forced to sacrifice security due to memory limitations.
