Biometrics offers substantial security benefits to the average consumer — including greater protection from identity theft, data theft and possibly even financial fraud. It is substantially more secure for privacy protection than using a basic password or four digit personal identification number (PIN). Since its inception, passwords have been the default credential for human authentication. From our personal computers to e-mails, from application software to online banking, passwords are compulsory to authenticate ourselves. In short, passwords are part and parcel of our daily lives. Although, the use of passwords could be argued as the most commonly used authentication tactic, they have a lot of security and maintenance challenges. Biometric authentication overcomes some of the major challenges we usually observe in a user ID and password based authentication system.
