Applications

SCS is a general purpose information embedding technique which is useful in many different watermarking applications. In this chapter, some example applications are presented. First, watermarking of chemical structure sets is investigated. It turns out that for this data type synchronization of the watermark decoder can be achieved relative easily. Therefore, a a complete watermarking system can be described. Next, experimental image watermarking schemes are discussed. The robustness of ST-SCS watermarks embedded in the block-DCT domain against optimized linear filtering attacks and image compression is investigated. Finally, the usefullness of SCS watermarking for integrity-verification of image data is demonstrated.
