Abstract
Systems and methods for maintaining data security using Luhn validation in a multiple domain computing environment are presented. Each domain includes a token generator that can generate tokens associated with sensitive data such as credit card numbers. The token generation algorithm includes a Luhn validation routine for producing a tokenized data string that either passes or fails Luhn. The possibility of token collision is eliminated by a token generation algorithm that embeds a domain designator corresponding to the active domain where the token was created. When multiple tokens represent the same sensitive data, the token manager returns a set of all such tokens found.
