    Abstract: The present invention is directed to a method of deterring the illicit copying of electronically published documents. It includes utilizing a computer system to electronically publish a plurality of copies of a document having electronically created material thereon for distribution to a plurality of subscribers and operating programming within the computer system so as to perform the identification code functions. The steps are to encode the plurality of copies each with a separate, unique identification code, the identification code being based on a unique arrangement of the electronically created material on each such copy; and, creating a codebook to correlate each such identification code to a particular subscriber. In some embodiments, decoding methods are included with the encoding capabilities. The unique arrangement of the electronically created material may be based on line-shift coding, word-shift coding, or feature enhancement coding (or combinations of these) and may be effected through bitmap alteration of document format file alteration.

    Abstract: A system for watermarking and distributing material includes a data processing apparatus, which operates as a watermark encoder. The data processing apparatus is operable to process an original material item to form a reduced-bandwidth-version of the material item, marked with a code word from a predetermined set of code words. The data processing apparatus is operable to form an impaired version of the material item from which a marked representation of the original material item can be formed. The impaired version is formed by subtracting the reduced-bandwidth-version of the material item from a copy of the original material item. As such, the impaired version can be mass distributed, but a representation of the original material item cannot be formed without the reduced-bandwidth-version of the material item. By watermarking the reduced-bandwidth-versions, a representation of the material item, formed by combining one of the marked reduced-bandwidth-versions with the impaired material item, can be uniquely identified. However, only a low bandwidth part of the material item need be watermark encoded, which is more easily distributable to individual recipients than watermarked copies of the original material item.

    Abstract: A method for detecting an embedded code which is embedded in a predetermined content and concatenates a plurality of component codes, comprising the steps of:

    dividing the embedded code into the plurality of component codes;
    decoding each of the component codes divided, thereby to obtain a plurality of residues pairs each comprising two residues, taking a plurality of integers which are predetermined and are relatively prime to each other, as moduli, the plurality of integers being inputted from a modulus storage section which stores k' different relatively prime numbers p i (i=1,2,...,k'), and
    calculating a user identification number of a colluder who made a collusion attack on the content, from the plurality of residue pairs, wherein
    the plurality of component codes are component codes that have a possibility to have a method of decoding at least one of the residues with respect to the user identification number of the colluder.
