Captcha as a Graphical Password

Now a days many security primal are based on the hard mathematical problems. Using this hard AI problems for security was emerging as an exciting new beauideal techinque, but it had been underexplore. here, we are presenting a new security primal based on hard AI problems, name as graphical password systems built on technology of Captcha methodology ,which we can call Captcha as a graphical passwords. CaGP is both a Captcha and a graphical password scheme. CaGP markses a number of security problems altogether name as relay attacks, online guessing attacks, and if it was scombine with dual-view technologies, shoulder-surfing attacks.[6] A CaGP password can found only creditability by automatic online guessing attacks even if the password is or was in the search set. CaGP also offers approach to the marks the well-known image hotspot problem password systems, such name as PassPoint, which may often lead to a weak password choices. CaGP is not a panacea, but it is offering reasonable security and usability and appears to fit well with some of the practical applications for improving online security.
