A system and method for dual key card dual database access control and identification

摘要: A system and method for dual key database access control identification (Dual Key System) to maintain security, organization privacy during electronic transactions. card maintains two separate distinct (201, 202), a public file (202) private (201), given cardholder. Each cardholder has record in each maintained 202); however, the records can only be integrated through use of identifiers stored on holder's (100). The allows data kept relatively small, anonymous processed more efficiently without knowing identity person whose information is being maintained. As result, an affinity-modeling engine constantly run against while maintaining security anonymity.
