چکیده

Many security primitives are based on hard mathematical problems. Using hard AI problems for security is emerging as an exciting new paradigm,but has been under explored a novel family of graphical password systems built on top of Captcha technology,which we call Captcha as a graphical passwords (CaRP).. CaRP addresses a such as online guessing attacks, relay attacks, and, if combined withdual-view technologies, shoulder-surfing attacks. CaRP also offers a novel approach to address the well-known image hotspot problem in popular graphical password systems,suchasPassPoints, that often leads to weak password choices.CaRP is not a solution, but it offers logical security and usability and appears to fit well with some practical applications for improving accessible security.

CAPCHA as Graphical Password

The most common computer authentication method is to use alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. For example, user tends to pick a passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember. In this paper, we conduct a comprehensive survey of the existing graphical password ...

Towards New Security Primitives Based on Hard AI Problems

Many security primitives are based on hard mathematical problems. Using hard AI problems for security has emerged as an exciting new paradigm (with Captcha being the most successful example). However, this paradigm has achieved just a limited success, and has been under-explored. In this paper, we motivate and sketch a new security primitive based on hard AI problems.
