Abstract

Client side watermark embedding schemes have been proposed as a possible solution for the copyright protection in large scale content distribution environments. In this framework, we propose a lookup-table based secure embedding system, designed for the Spread Transform Dither Modulation (ST-DM) watermarking algorithm, that outperforms Spread Spectrum based systems.
