Image algorithm for watermarking relational databases based on chaos

Abstract

Database watermarking is an important branch of information hiding technology, and it is chiefly used to protect copyright. This paper creatively proposes a novel method for watermarking relational database, which uses the encrypted images sequence 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. © 2010 Springer-Verlag Berlin Heidelberg.
