An Image Based Algorithm for Watermarking Relational Databases
As a tool for interests in both storing and managing data, relational database is widely used in many information systems. This paper studies an improved algorithm to watermark numeric attributes in relational databases for copyright protection. We propose a novel watermarking method, which embeds an image watermark into relational results verify the effectiveness of the database. Experimental results show that the proposed scheme is robust against various forms of attacks.
