With the use of internet becoming indispensable not only in communication and business but specifically in e-banking and e-commerce, the user authentication is become mega important in today's technology dominant era and there is an imperative necessity for technologies have the potential to make authentication secure and foolproof.Security and privacy issues have remained a challenge for years. These become more crucial when it's about the security and privacy of data in electronic form. Personal identification (authentication) plays a vital role in modern society. It can help in achieving the security by the identification of an individual. Information technology widely uses Passwords or Personal Identification Numbers (PINs) to verify a user to a system. Recognition of a PIN does not, however, mean recognition of the person's identity. Anybody can have gained access to a PIN, a card or any other 'key' that is being used to get access to a device. This means that systems that are dependent on high access security cannot always rely on these kinds of tokens, since they cannot ensure that a user is who s/he claims to be. Biometrics could be used to gain trust to a device instead of PINs or passwords. biometrics or characteristics are tightly connected to an individual and cannot be forgotten, shared, stolen or easily hacked. These characteristics can uniquely identify a person, replacing or supplementing traditional security methods by providing two major improvements: personal biometrics cannot be easily stolen and an individual does not need to memorize passwords or codes. Since biometrics can better solve the problems of access control, fraud and theft, more and more organizations are considering biometrics a solution to their security problems.
