    摘要: An improved method of watermarking picture identification documents (IDs) such as passports, driver's licenses, identification cards and the like which combines biometric information with digital watermarking to provide an improved secure picture ID document and authentication of same. A facial image—that is part of the identification document—is processed such that particular facial features are extracted from the overall facial image. The extracted features are used to generate a watermark key that is subsequently used to embed a unique watermark into the facial image or other location on the identification document.

    摘要: A Discrete Fourier Transform watermark for use with digital images/video. A Y component of a Y, U(Cb), V(Cr) digital data stream representing color components of digital video is extracted as the digital data for embedding the watermark. The digital data is then scaled to a standard size. A Discrete Fourier Transform (DFT) is performed on the digital data, and a magnitude domain of the Discrete Fourier Transform is computed. The watermark is embedded into selected frequency bands of the computed magnitude domain of the Discrete Fourier Transform, thereby creating a watermarked magnitude domain. The selected frequency bands comprise one or more middle frequency bands, and the middle frequency bands comprise a band of circular rings of the magnitude domain. An inverse Discrete Fourier Transform is performed on the watermarked magnitude domain to reconstruct the digital data with the embedded watermark.

    摘要: An encryption-enabled entropy coder for a multimedia codec is disclosed. The entropy coder implements a randomized Huffman coding scheme without storing multiple sets of Huffman tables in a ROM. The entropy coder includes a ROM storing a single set of code tables, a table lookup section coupled to the ROM which converts symbols to original codewords and vice versa by performing table lookup, and a table randomizer section for converting original Huffman codewords to randomized Huffman codewords and vice versa using an isomorphic code generator algorithm. The table randomizer section performs the conversion based on a key hopping sequence generated by a pseudorandom bit generator using an encryption/decryption key.

    摘要: A system for creating non-repudiation (undeniable) watermarks, wherein a content provider uses outside distribution entities to distribute media content supplied by the content provider. Content watermarked by a distribution entity using this system is undeniably recognizable by the content provider as originating with that particular distribution entity. In other words, given N distribution entities, the content provider is able to tell which particular distribution entity watermarked the media content. The system does not allow any distribution entity to watermark media content so that would appear to have been watermarked by another distribution entity and the system does also not allow the content provider to watermark media content so that would appear to have been watermarked by a particular distribution entity. Consequently, this allows the content provider to place a high degree of trust in the identification of the distribution entity by means of the watermark.
