GRAPHICAL PASSWORD FOR EMAIL APPLICATION BY PERSUASIVE CLICK POINTS USING CENTERED DISCRETIZATION?

The general method which is in use nowadays is text based or alphanumeric based passwords. But this method as such has not proved to be efficient in security against password guessing attacks. Either the password is easy to guess or hard to remember. To overcome this problem we have developed authentication technique which uses pictures as passwords. According to a survey of graphical password techniques they are classified into two categories: recognition based and recall based approaches. We are also going to study the strengths and limitations of each method and will also focus on future scopes in this field. This paper focuses on integrated evaluation of the Persuasive Cued Click Points graphical password authentication system and security using centered discretization technique. This paper also gives the solution for prevention from emergence of hotspots. Hotspots are the portion of images which are more likely to be chosen as click points. Also we are here proposing a new technique for graphical authentication.
