Simple Text Based Shoulder Surfing Resistant Graphical Password Using CAPTCHA

Security

A Lot of security primitives are depend on more challenges and it will be resolved by some mathematical formulations. For security using high AI Problems and it’s become an evaluation for new pattern of security, but not explored well. In our studies we define Captcha as graphically password, graphically password system build on captcha technology mainly on hard AI problems we will present new security primitives. Captcha is combination of captcha and graphical password. CaRP is address multiple security issue like shoulder surfing attack, if combined with dual view technology, relay attack and online guessing attack. CaRP alone becomes inefficient to prevent all security, hence this paper makes a survey of the various security measures for secure password schemes and gives a clear picture of the efficiencies of the different techniques. For improving online security highly secure password offers usability and reasonable security and appears suit well with practical applications.
