摘要：In this paper we present a security primitive whichis a novel family of graphical password systems based on hardAI problem which is called as Captcha as a graphicalpasswords . It is the combination of a Captcha and a graphicalpassword. It offers a number of security problems such asrelay attacks online guessing attacks and many more. CaRPalso prevents shoulder surfing attack if it is combined withdual view technology . This new security primitive offers anapproach to present a well known image hotspot problem inpopular graphical password systems , that often leads to weakpassword choices leading to leakage of password CaRP offersreasonable security which appears to fit well with some of thepractical applications for improving security online.
