Spyware prevention using graphical passwords

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.
