Secure Client-Side ST-DM Watermark Embedding - 2010

ABSTRACT:

Client-side watermark embedding systems are proposed as a potential resolution for the copyright protection in giant-scale content distribution environments. In this framework, we propose a brand new look-up-table-based secure consumer-aspect embedding scheme properly designed for the unfold transform dither modulation watermarking methodology. A theoretical analysis of the detector performance beneath the most known attack models is presented and also the agreement between theoretical and experimental results verified through several simulations. The experimental results conjointly prove that the benefits of the informed embedding technique in comparison to the spread-spectrum watermarking approach, that are well known within the classical embedding schemes, are preserved in the consumer-aspect scenario. The proposed approach permits us to successfully mix the safety of client-facet embedding with the robustness of informed embedding ways.
