Ramani Sagar V . Watermark based Copyright Protection for Relational Database. International Journal of Computer Applications. 78, 2 ( September 2013), 22-28. DOI=10.5120/13462-0713
As information hiding, the digital watermark techniques have been attracting more interests in both research and industrial fields. Relational database is widely used in many information systems, as a tool for storing and managing a data. Major issue to protect the copyright of relational data. In order to make watermarking information more intuitive and easier to identify and to give authorization to the database this idea has been proposed. Ownership verification of a database by inserting an imperceptive watermark in such a way to provide robustness and security against attempts to remove the watermark. To prove ownership of the database watermarking is done using image. Image is converted into the row bits and row bits is encrypted using MD5 security algorithm . This row bits will be embed into the database attribute in terms of watermark. To check the performance of this scheme will be tested based on different types of attacks on the database which shows the robustness of this scheme.
