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.

Luhn validation and data security across multiple active domains

Systems and methods for maintaining data security across multiple active domains are presented. Each domain includes a token generator that can generate tokens associated with sensitive data such as credit card numbers. The primary domain includes a centralized key manager. In one embodiment, each domain includes its own local data vault and a replica of each data vault associated with every remote domain. Any domain can access the data vaults (local and replica) and retrieve a token created by any other domain. 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 in the data vaults.
