Biometric Based User Authentication in Smart Phones

Abstract

Authenticity of a user is considered to be as one of the most sensitive issue that requires attention especially in the case of smart phones, where the statistics concludes that, almost half of the smart phone users use no authentication system since they need to unlock their devices very often and the complex passwords are difficult to remember. Also, a lot of time is consumed while entering the passwords or patterns each time the user wants to log in. The Basic assumption of this approach is that the existing user authentication methods for smart phones, and current statistics of user. To recall, some people have a habit of writing down their passwords at places or use same password for multiple accounts. Even if the password is complex, attacks like key logger, social engineering or shoulder surfing are commonly being used. Authentication in smart phones elaborating the reason behind why people do not like to have any method based on graphical password and behavioral biometric has been proposed in this paper which is expected to be easier, secure and faster at the same time.
