Abstract :
The author has applied a guided scrambling (GS) technique, usually used for a recording channel, to digital watermarking (Kunisa, A., Proc. SPIE: Security and Watermarking of Multimedia Contents, V, 2003). The paper modifies the GS-based watermarking algorithm to a block-wise watermarking system. It is well suited for compression processing, such as JPEG or JPEG2000, and is readily applied to digital cameras.
