Abstract
A method and system for performing an operation on protected sensitive data. A processor of a data processing system receives, from a computing system: (i) the protected sensitive data, (ii) an identification of an operation that accesses and utilizes the protected sensitive data during performance of the operation, and (iii) a request to perform the operation, wherein the computing system is external to the data processing system. The processor de-protects the received protected sensitive data, which generates unprotected sensitive data from the protected sensitive data. The processor performs the operation, which includes accessing and utilizing the unprotected sensitive data and generating a result. After the operation is performed, the processor re-protects the unprotected sensitive data, which restores the protected sensitive data. The processor sends the result to the computing system.
