Abstract
Systems and methods to tell apart computers and humans using image recognition task having a dynamic graphical arrangement of randomly selected images. The images can be arranged as a grid or matrix for presentation on a device display for authentication of a user as human. The kinds of graphical images can be derived from a selected category for the image recognition task. A series of randomly generated access codes corresponding to the images can be displayed with the images. The user may enter the access codes corresponding to images from the selected category. An authentication server can compare the access code entry to an authentication reference code corresponding to the particular arrangement of images. The selection of images, their arrangement and their corresponding access codes, may dynamically change in between verification sessions.
