System and method for authenticating an end user

A computer program product, comprising a computer-usable storage medium having a computer-readable program code stored therein, said computer-readable program code containing instructions that when executed by a processor of a computer system implement a method for authenticating an end user, said method comprising:

• generating a first pattern in response to receiving an authentication request from said end user, said first pattern comprising a plurality of randomly colored quadrilaterals wherein one quadrilateral of said plurality of quadrilaterals is associated with said end user;
• generating a second pattern in response to receiving confirmation that said end user received said first pattern, said second pattern comprising a plurality of colored nodes, said plurality of colored nodes containing a first subset of nodes matching both color and location to a second subset of nodes residing in a transparent credit card being controlled by said end user;
• determining an authenticity status of said end user by comparing a third subset of nodes received from said end user with said first subset of nodes, said third subset of nodes being received in response to sending said second pattern to said end user, said end user having generated said third subset of nodes by overlaying said transparent credit card on top of said second pattern and selecting at least one node which displays a color not being black;
• and
• sending said determined authenticity status to said end user via an output device.

A computing system comprising a processor coupled to a computer-readable memory unit, said memory unit comprising a software application, said software application comprising instruction that when executed by said processor, implement a method for authenticating an end user, said method comprising:

• generating a first pattern in response to receiving an authentication request from said end user, said first pattern comprising a plurality of randomly colored quadrilaterals wherein one quadrilateral of said plurality of quadrilaterals is associated with said end user;
• generating a second pattern in response to receiving confirmation that said end user received said first pattern, said second pattern comprising a plurality of colored nodes, said plurality of colored nodes containing a first subset of nodes matching both color and location to a second subset of nodes residing in a transparent credit card being controlled by said end user;
• determining an authenticity status of said end user by comparing a third subset of nodes received from said end user with said first subset of nodes, said third subset of nodes being received in response to sending said second pattern to said end user, said end user having generated said third subset of nodes by overlaying said transparent credit card on top of said second pattern and selecting at least one node which displays a color not being black;
• and
• sending said determined authenticity status to said end user via an output device.

A process for supporting computer infrastructure, said process comprising providing at least one support service for at least one of creating, integrating, hosting, maintaining, and deploying computer-readable code in a computing system, wherein said code in combination with the computing system is capable of implementing a method for authenticating an end user, said method comprising:

• generating a first pattern in response to receiving an authentication request from said end user, said first pattern comprising a plurality of randomly colored quadrilaterals wherein one quadrilateral of said plurality of quadrilaterals is associated with said end user;
• generating a second pattern in response to receiving confirmation that said end user received said first pattern, said second pattern comprising a plurality of colored nodes, said plurality of colored nodes containing a first subset of nodes matching both color and location to a second subset of nodes residing in a transparent credit card being controlled by said end user;
• determining an authenticity status of said end user by comparing a third subset of nodes received from said end user with said first subset of nodes, said third subset of nodes being received in response to sending said second pattern to said end user, said end user having generated said third subset of nodes by overlaying said transparent credit card on top of said second pattern and selecting at least one node which displays a color not being black;
• and
• sending said determined authenticity status to said end user via an output device.
