一种基于混沌变换的关系数据库水印算法

Abstract

Abstract:

An algorithm based on chaos transform for relational database watermarking is proposed in this paper,which uses the encrypted images sequence as watermarks and embeds them into the database according to the weight of attributes.The combination of the watermarking technology with the chaos theory improves the invisibility of watermarks.And watermark detection is blind.Experimental results show that the proposed scheme has good invisibility and robustness against various forms of attacks.

Key words: relational database watermarks;chaos transform;copyright protection;robustness
