A Watermarking Algorithm for Relational Database Based on Image

Abstract:

According to the particularity of relational databases, a new watermarking relational database based on image is proposed combined with the existing digital watermarking technique. Watermark image is scrambled using Arnold transform first, and then numeric attributes satisfying the requirement of the effective bits in relational database are partitioned using the K-Means algorithm, at last the binary 3-bit-set sequences of watermark image are embedded into the clusters. Experiment indicates that the algorithm possesses better robustness and invisibility and better practical value.
