    We propose a watermarking scheme that is based on pixel position shifting (PPS). The proposed scheme will shift the watermark locations in the frequency domain such that the watermark locations are difficult to obtain by just using the watermarked image. To enhance the reliability of the retrieval of the watermark data, a (8,4) distance-4 Hamming code is used. The new proposed algorithm was thorou... View full abstract»

    One of the main problems in home networked systems is the wide diversity of technologies, application requirements and cost allowance for devices and systems in general. This is translated to a division into different islands of technology that goes down to single manufacturer systems, thus blocking the way to the system integration as the main reason for the existence of the network. It is widely... View full abstract»

    Because the picture quality of watermarked motion pictures must not be degraded by the watermarking, this paper describes a new module that controls watermarking processes. The module uses a new human sight model to optimize watermark strength for each frame of a motion picture, and it prevents flickering by limiting the frame-to-frame change in watermark strength. Another advantage of this module... View full abstract»
