A Speech Based Algorithm for Watermarking Relational Databases

This paper studies a novel scheme of watermarking relational databases for copyright protection. Speech signal is introduced as watermark to be embedded into the relations; associated novel watermark insertion algorithm and detection algorithm are proposed. Thus, the watermark signal in this method is expected to be more meaningful and has closer correlative to the copyright holder. Experimental results verify that the proposed method is feasible, effective and robust.
