Speech Algorithm for Watermarking Relational Databases Based on weighted

摘要

We enunciate the need for watermarking database relations to deter data piracy, identify the characteristics of relational data that pose unique challenges for watermarking. This paper creatively proposes a novel method for watermarking relational database, which uses speech signal as watermark embed into database according to the weight of attributes. Experimental results show that the proposed scheme is robust against various forms of attacks. Our approach is more intuitive, and it support easy watermark identification.
