An additive-attack-proof watermarking mechanism for databases' copyrights protection using image
Xiang Zhou, Min Huang, Zhiyong Peng · 2007
This paper discusses the feasibility of embedding a bit map image (BMP file) into the relational databases for protecting data's copyrights and the term of WDI (Watermarking Databases using Image) is proposed. An error correction approach of BCH (Bose-Chaudhuri-Hocquenhem) coding is used for enhancing the robustness of the algorithms. And a Trusted Third Party (TTP), which can trigger watermarking mobile agents to insert and detect watermark, is introduced to resist the additive attack and invertibility attack. Further more, we also analyze the resilience of the algorithm theoretically based on the principles of statistics in detail. Experiments showed that the approach proposed in this paper is robust to many kinds of attacks so that the copyrights can be effectively protected.
