Method and apparatus for securing passwords and personal identification numbers

Image Number 4 for United States Patent #6253328.

A method for securing passwords and personal identification numbers utilizes a mastercode. At least ten characters are selected for the mastercode. The selected characters are randomly associated to a corresponding digit, wherein the association defines the mastercode. A numeric sequence is translated into a corresponding character sequence using the mastercode. The corresponding character sequence is expanded into an ordinary word. An apparatus for implementing the method is also described. For enhanced security the mastercode can be embedded within a mastergrid camouflaging the mastercode.
