Patent ID: 7522723

Claim:
A method comprising converting a first set of predefined information on a server computer to an integer x using a text to number conversion scheme; determining a first public key exponent e which is computed as any function of x that results in an odd integer for e; selecting two prime numbers p and q, wherein p−1 and q−1 are relatively primes to e, and then computing a first key modulus n=p times q and a Euler Totient Function ø=(p−1)(q−1); computing a first private key exponent d such that ed=kø+1, wherein k and d are integers storing the first private key exponent d and the first key modulus n in a database or file on the server computer, so that the first private key exponent d and the first key modulus n are related to a first user identification of a first user and the first set of predefined information; and permanently deleting x, p, q, e and ø on the server computer so that there is no record of x, p, q, e and ø on the server computer.
