Relational Databases Watermark Technique Based on Content Characteristic

With the development of the Internet and wide applications of databases, the databases providers are worrying about their ownership of the databases. Combined with the digital watermark technique and the characteristic of relational databases, a scheme of watermarking relational databases based on content characteristic is proposed in this paper. The corresponding algorithms of watermark embedding and detection are proposed and analyzed by probability. Then some watermark embedding and detection experiments are conducted, and the results are analyzed and discussed. In additional, some attacked experiments are conducted to prove the feasibility and the robustness of the proposed algorithms
