Captcha as Graphical Passwords-A New Security Primitive Based on Hard AI Problems

Captcha as Graphical Passwords—A New Security Primitive Based on Hard AI Problems Many security primitives are based on hard mathematical problems. Using hard AI problems forsecurity is emerging as an exciting new paradigm, but has been under-explored. In this paper, we present a new security primitive based on hard AI problems, namely, a novel family […]
