Abstract
Systems and methods for providing authentication using an arrangement of dynamic graphical images, which may display a popup element while a pointing device indicator is over a graphical image. The graphical images can be arranged as a grid or matrix for presentation on a device display for authentication of a user. The kinds of graphical images can be derived from a designated authentication category and non-authenticating categories. A series of password elements corresponding to the graphical images can be displayed with the graphical images. The user may enter the series of one or more password elements corresponding to graphical images from the authentication category which combine to form a password entry. An authentication server can compare the password entry to an authentication password corresponding to the particular arrangement of dynamic graphical images. The selection of graphical images, their arrangement and their corresponding password elements, may dynamically change in between authentication processes.
