Abstract:
1. A method for authenticating an end user, said method comprising: generating a login field in response to receiving an authentication request from said end user, said login field comprising a login node matrix and at least one login offset, said login node matrix comprising a first set of transparent nodes and a first set of opaque nodes, said at least one login offset comprising both random characters and a unique string of characters known only by said end user; determining an authenticity status of said end user by comparing a subset of nodes received from said end user with said first set of transparent nodes, said subset of nodes being received in response to sending said login field to said end user, said end user having generated said subset of nodes by overlaying a transparent credit card on top of said login field and aligning said login offset with a card offset residing in said transparent credit card and then selecting at least one node which is not opaque; and sending said determined authenticity status to said end user via an output device.
