.NET Project On Captcha as Graphical Passwords—A New Security Primitive Based on Hard AI Problems


Many safety primitives are based on tough mathematical issues. The usage of tough AI issues for protection is emerging as an exciting new paradigm, however has been under-explored. In this project, we present a new protection primitive primarily based on hard AI issues, specifically, a family of graphical password structures constructed on top of Captcha technology, which we call Captcha as graphical passwords (CaRP). CaRP is both a Captcha and a graphical password scheme. CaRP addresses a number of security issues altogether, such as online guessing attacks, relay attacks, and, if combined with dual-view technologies, shoulder-surfing attacks. Considerably, a CaRP password may be found handiest probabilistically by automated online guessing attacks even though the password is within the search set. CaRP also offers a unique method to deal with the well-known photo hotspot problem in popular graphical password structures, such as PassPoints, that regularly leads to susceptible password selections. CaRP isn’t always a panacea, but it gives reasonable protection and usability and appears to fit properly with some practical applications for enhancing online protection.
