Transparent Data Encryption eliminates the need to embed encryption routines in existing applications and dramatically lowers the cost and complexity of encryption. With a few simple commands, sensitive application data can be encrypted. Automatic Encryption of Sensitive Information Most encryption solutions require specific calls to encryption functions within the application code. This is expensive because it typically requires extensive understanding of an application as well as the ability to write and maintain software. In general, most organizations do not have the time or expertise to modify existing applications to make calls to encryption routines. Oracle
