Abstract
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, storing in a database records containing the obfuscated personal identifier, storing the secret value in a identifier translation device, receiving at a request preparer a record request identifying a requested record using a non-obfuscated personal identifier, and operating the request preparer to direct the identifier translation device to translate the non-obfuscated personal identifier into an obfuscated personal identifier using the secret value stored in the identifier translation device and using the obfuscated personal identifier in a query to the database.
