Xuemin Zhao, Lingling Li, Qingtao Wu · Physics Procedia · 2012
As a tool for interests in both storing and managing data, relational database is widely used in many information systems. In this paper, a novel method of watermarking is presented to protect relational databases copyright. We propose a novel multiple watermarking scheme, which embeds multi-media watermarks into relational database. 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.
