CaRP For User Authentication System Using Mobile Interface

Many security techniques are used for authentication of user. Text based passwords are used by many users for their authentication. But the security as at high risk when using text based passwords. Graphical passwords are another way to authenticate user. So in this paper we are introducing the security technique related to AI problem. Captcha is used to create the graphical passwords. Means puzzles can be given to the user at the time of login process. But there are also chances of attacks on graphical password such as eavesdropping, shoulder surfing attacks etc. To overcome the drawback of graphical password and also to provide more secure approach, this paper introduces the mobile interface. In that the random questions are sent to the user & #039, s mobile then user will give the answers to the questions which he has been asked during the registration process. Due to this, even if the graphical password is intercepted but the interceptor is not able to give the answer because questions are send only to authorize person & #039, s mobile.
