A secure data management system and method which separates query processing operations from transaction management and data storage operations to provides secure outsourced data management assurances while remaining practically viable for commercial deployment. The secure data management system and method includes a untrusted database module which performs transaction management and data storage operations on encrypted data from at least one network accessible computer and a trusted database module which processes user generated queries and commands on a secure client device by selectively accessing, decrypting and re-encrypting the encrypted data on the at least one network accessible computer. In this regard, total privacy can be maintained while still outsourcing transaction management and data storage operations to untrusted third parties because all sensitive operations are performed in a secure environment and the transaction management and data storage operations can only access encrypted data. |
