Abstract
A system, method and apparatus for protecting sensitive data in a file that has been replaced with pointer(s) for each sensitive data. The sensitive data items are protected by restricting subsequent access to and use of the sensitive data items via the pointers by: receiving a first request for data stored in a file on the data storage, determining whether the requested data includes at least one of the pointers, providing the requested data whenever the requested data does not include any of the pointers, and performing the following steps whenever the requested data includes at least one of the pointers: sending a second request containing the pointer(s) included in the requested data to the server that authenticates the second request, denying the first request whenever the authentication fails, and receiving and providing the extracted data item(s) corresponding to the pointer(s) included in the requested data whenever the authentication succeeds.
