Database environment would not be completely secured without consideration of database encryption technology. The term database encryption refers to the practice of obscuring the meaning of a piece of data by means of encoding before storing it in tables. The database encryption is implemented in such a way that it can only be decoded, read, and understood by people for whom the data is intended. It is the process of encoding data to prevent unauthorized parties from viewing or modifying it.

Probably, the most widely used application of database encryption is in the area of data protection. The information that a business owns is invaluable to its productive operation; consequently, the protection of this information is paramount.

Database encryption protects the files that are written to the column of a table. This information protection is vital in the event of theft of the computer itself or if an attacker successfully breaks into the system.

To ensure a tight-leashed security, Daffodil DB supports various encryption algorithms, such as idea, DES, and Twofish. The users can encrypt objects and data before storing them in a table with the help of these proven encryption algorithms.

Process of database encryption in Daffodil DB is efficient and simple. While creating a new database users can specify the value for key and the algorithm, which is used for encrypting the objects and data contained in tables. The following things should be considered before applying encryption techniques:

• Managing security with database encryption becomes more difficult if the office has multiple employees, who share the user information.
• The super user information can be changed as the super user is in-charge of the Daffodil DB database. Someone logged in as a super user can make use of the data stored in your table.
