Watermarking relational database using image
Zhihao Zhang, Xiaoming Jin, Jian-Min Wang, Deyi Li · 2005
As an embranchment of information hiding, the digital watermark techniques have been attracting more and more interests in both research and industrial fields. As a tool for storing and managing data, relational database is widely used in many information systems. It is a crucial issue to protect the copyright of relational data. In order to make watermarking information more intuitive and easier to identify, We propose a novel watermarking method, which embeds an image watermark into relational database. Experimental results verify the effectiveness of the proposed method.
