Abstract:
1. A computer based method of authentication, comprising the steps of: (a) displaying a field operatively arranged for entry of data representative of a first mathematical function of a first set of digits in a person's Social Security Number, wherein said first set of digits comprises any plurality of different digits of said Social Security Number; (b) displaying instructions to said person indicating said first mathematical function to be performed by said person to arrive at said representative data; (c) displaying a field operatively arranged for entry of other data representative of the identity of said person; (d) receiving said data representative of said first mathematical function of said first set of digits in said person's Social Security Number with a processor; (e) receiving other data representative of the identity of said person with said processor; (f) determining said person's Social Security Number from said other data representative of the identity of said person, wherein said determining is accomplished by a lookup process in a database with said processor; (g) performing said first mathematical function of said first set of digits in said person's Social Security Number with said processor; (h) comparing a result of said performing said first mathematical function of said first set of digits in said person's Social Security Number with said received data representative of said first mathematical function of said first set of digits in said person's Social Security Number with said processor to authenticate said person's identity; and (i) repeating at least steps (a)-(d) and (g)-(h) with new instructions for a second mathematical formula on a second set of digits in said Social Security Number if said comparing step (h) yields a match, wherein said second set of digits differs from said first set of digits and/or said second mathematical function differs from said first mathematical function.
