ABSTRACT:
The present invention generally is directed to systems, methods, and articles of manufacture for securing sensitive information involved in database transactions. Embodiments of the present invention selectively encrypt only portions of transactions involving sensitive data, thereby reducing or eliminating the processing overhead resulting from wastefully encrypting non-sensitive data. The sensitive data may be identified by a document. The document may be accessed by a requesting entity to determine which portions of a query should be encrypted prior to sending the query to a database server over a network. The document may also be accessed by a database server to determine which portions of query results should be encrypted prior to sending the query results to the requesting entity over the network.
