Patent ID: 7616764

Claim:
A computer implemented system for providing encryption of a user identifier, the system comprising: a user computer and a server computer configured to communicate with each other via a network, wherein the user computer is configured to: display a graphical user interface comprising: a first wheel-shaped image and a second wheel-shaped image, wherein the first wheel-shaped image extends radially outward of the second wheel-shaped image and includes a first plurality of sectors, each sector of the first wheel-shaped image including an image from a set of predetermined alphanumeric elements, and wherein the second wheel-shaped image includes a second plurality of sectors, each sector of the second wheel-shaped image including an image of a marker; and an image of a first positioning button that is adapted to cause movement of a first user selected sector of the second wheel-shaped image from a first position relative to the first wheel-shaped image to a second position relative to the first wheel-shaped image upon actuation of the first positioning button by a user, the movement of the first user selected sector defining a displacement, the displacement being associated with a first element of a user identifier; and transmit displacement data representative of the displacement to the server computer, and wherein the server computer is configured to: receive the displacement data and determine the displacement from the displacement data; and determine a user selected marker associated with the first user selected sector by correlating the displacement with the first element of the user identifier.
