    Abstract: The present invention relate generally to digital watermarking. One claim recites a method including: obtaining first data representing a first chrominance channel of a color image or video, where the first data comprises a watermark signal embedded therein; obtaining second data representing a second chrominance channel of the color image or video, the second data comprising the watermark signal embedded therein but with a signal polarity that is inversely related to the polarity of the watermark signal in the first data; combining the second data with the first data in a manner that reduces image or video interference relative to the watermark signal, said act of combining yielding third data; using at least a processor or electronic processing circuitry, processing the third data to obtain the watermark signal; and once obtained, providing information associated with the watermark signal. Of course, additional combinations and claims are provided as well.

    Abstract: The application provides a method for partitioning a watermark image with western language characters, comprising: partitioning a western language characters image along rows and columns to form a plurality of character image blocks; identifying valid character image blocks from the formed character image blocks; counting sizes of the valid character image blocks to determine if the image corresponds to a document with a large font size or a document with a small font size; dividing words in the image into a plurality of groups, wherein each divided group in the document with large font size has different numbers of words from that with small font size; and dividing equally the divided word groups into multiple portions corresponding to watermark image blocks. The application further provides a device for partitioning a watermark image with western language characters. The operability of watermark embedding process can be ensured through the above technical solution.

    Abstract: A digital watermark embedding apparatus includes an interface circuit which acquires video data and digital watermark information, and a processor which embeds the digital watermark information into the video data. The processor is adapted to, for each symbol contained in the digital watermark information, set a time segment, cause the area of a watermark pattern formed by a plurality of pixels having a prescribed value, and superimposed on each image contained in the video data, to vary in periodic fashion over time in the time segment according to the value of the symbol contained in the digital watermark information, and correct, using the prescribed value, the value of each pixel contained in a region where each image in the video data and the watermark pattern corresponding to that image overlap each other.
