SYSTEM AND METHOD FOR OBFUSCATING AN IDENTIFIER TO PROTECT THE IDENTIFIER FROM IMPERMISSIBLE APPROPRIATION

摘要

A system and method of operating a database system to protect personal identifiers from being revealed. The system and method obfuscates personal identifiers using a secret value, stores records containing the obfuscated personal identifier in a database, stores the secret value in an identifier translation device, receives, at a request preparer, a record request identifying a requested record using a non-obfuscated personal identifier, and operates the request preparer to direct the identifier translation device to translate the non-obfuscated personal identifier into an obfuscated personal identifier that is used in a query to the database.
