1. A method of eliminating token collision in a multiple domain environment, said method comprising the computer-implemented steps of: establishing a first data vault located at a first domain; establishing a plurality of second data vaults, each located at one of a plurality of second domains; receiving at said first domain a sensitive data string for tokenization; generating a new token according to a token generation algorithm wherein said new token is independent of at least a portion of the data in said sensitive data string, and wherein said token generation algorithm is configured to embed within said new token a domain designator corresponding to said first domain; storing said token in said first data vault; creating a replica of said first data vault at each of said plurality of second domains; and creating a replica of each of a said plurality of second data vaults at said first domain.

The method of claim 1 , wherein said domain designator comprises a single alphabetic character selected from the fifty-two upper-case and lower-case letters of the English alphabet.
