Abstract:
1. A method for authenticating an end user, said method comprising: generating, by a processor of the computer system, a first pattern comprising a plurality of colored quadrilaterals; said processor generating a second pattern comprising a first plurality of colored nodes, said first plurality of colored nodes containing a first subset of nodes; said processor sending the first pattern and the second pattern to the end user; after said sending the first pattern and the second pattern to the end user, said processor receiving a location and color of each node of a third subset of nodes from the end user; said processor determining whether the end user is authentic by determining whether required conditions are satisfied, wherein the first and second patterns are configured such that if a transparent credit card were overlaid by the end user on top of the login field then a second subset of nodes of a second plurality of colored nodes residing in the transparent credit card would match in color and location the first subset of nodes, wherein the third subset of nodes is a subset of the second subset of nodes residing in the transparent credit card, and wherein the required conditions are that each node in the third subset of nodes (i) corresponds to a unique node of the first subset of nodes and (ii) has a color that matches a specific color in one quadrilateral of the plurality of colored quadrilaterals, wherein the one quadrilateral represents a secret of said end user that is shared with the computer system; and after said determining whether the end user is authentic, said processor sending to the end user via an output device a communication of whether the end user is authentic.
