Advanced Security Functions Based on CaRP Using Random Image Grid

Abstract

A new security primitive for secure applications are required these days. Captcha technology solves the most
security based problems. Captcha as graphical passwords (CaRP) is proposed in this work along with secure upload of
events and an Improved method of CaRP. We consider an event update application, where security is highly required. CaRP
addresses a number of security problems altogether, such as online guessing attacks, relay attacks, and, if combined with
dual-view technologies, shoulder-surfing attacks. CaRP deals only with the security related to authentication, in most of the
application, only authentication security is not enough, thus we develop a secure event upload model even after CaRP
authentication. This system offers high security to the authentication and published content Along with an Improved Method
of CaRP.
