Oracle Transparent Database Encryption

To comply with company and federal regulations, you need a solution immediately, without any complex coding. A new feature in Oracle Database 10g Release 2 lets you do just that: You can declare a column as encrypted without writing a single line of code. When users insert the data, the database transparently encrypts it and stores it in the column. Similarly, when users select the column, the database automatically decrypts it. Since all this is done transparently without any change to the application code, the feature has an appropriate name: Transparent Data Encryption (TDE).
