Abstract:
1. A method for authenticating an end user, said method comprising: receiving, by a processor of a computer system, an authentication request from said end user; in response to said receiving the authentication request from said end user, said processor generating a first pattern, said first pattern comprising a plurality of randomly colored quadrilaterals wherein one quadrilateral of said plurality of quadrilaterals is associated with said end user and has a specific color; said processor generating a login field comprising a second pattern, said 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 said 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 in the login field, 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 the specific color in said one quadrilateral of said plurality of quadrilaterals; and after said determining whether said end user is authentic, said processor sending to said end user via an output device a communication of whether the end user is authentic.
