Digital watermark, relational data, data security, and copyright protection


To protect the copyright of relational database is an important task. It’s a great challenge as well as has a practical application. In this paper, a novel method of watermarking is presented to protect relational databases copyright. The watermark embedding and extraction algorithms are specified, the results of the corresponding watermark experiments and the attack experiments verify that the proposed method is correct, feasible and robust.
