Spyware prevention using graphical passwords

Abstract

our future work will be based on Click-based graphical password schemes require a user to click on a set of points on one or more presented background images. With the Pass Points and to create users to a password by clicking five ordered points anywhere on the given image.  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. Notably, a CaRP password can be found only probabilistically by automatic online guessing attacks even if the password is in the search set. To log in, users must correctly the repeated sequence of clicks, with each click falling within the acceptable tolerance of original point. To implemented this aspect, along with a scheme converting the user-entered graphical password into a cryptographic verification key and “robust discretization” scheme. It consisted of three overlapping grids (invisible to the user) used to determine whether the click-points are login attempt were close enough to the original points to be accepted.
