摘要：Various security primitives uses hard mathematical problems. Use of hard AI problems for security isemerging and exciting new pattern, but has not yet been explored. In our project, we present a new security primitivebased on hard AI problems, this system is named as Captcha as graphical passwords (CaRP). CaRP is Captcha as wellas graphical password scheme. CaRP symbolize a number of security problems together, such as online guessingattacks, relay attacks, and shoulder-surfing attacks. Generally, a CaRP password can be found only probabilistically byautomatic online guessing attacks even if the password is in the search set CaRP also offers well approach to addressthe well-known image hotspot problem in popular graphical password systems, like PassPoints, that generally leads tochoices of weak password
