Abstract: A watermarking system comprises an encoding data processor operable to generate at least one marked version of an original item of material by introducing one of a predetermined set of code words into a copy of the original material item. The encoding processor comprises a code word generator operable to form the code word by generating a plurality of code word coefficients, and an encoder operable to combine the code word coefficients with the material item, and an adaptation processor. The adaptation processor is operable to adapt the strength of the code word coefficients or the material item samples in accordance with a relative sensitivity of the material item samples to carry the code word coefficients. The strength of the watermark is therefore adapted in accordance with the sensitivity of the material item to carry watermark code word coefficients. As a result there is a reduced likelihood of an attacker identifying parts of the material item to which the watermark code word has been added. A likelihood of a successful attack is thereby reduced whilst maintaining a desired false negative detection probability.The watermarking system finds particular application in identifying a point of distribution of pirate copies of video material generated by capturing the watermarked image, using, for example, a camcorder in a cinema.

Abstract: An encoding data processing apparatus generates at least one water marked version of an original item of material formed by introducing one of a predetermined set of code words into a copy of the original material item. The apparatus has a bandwidth adaptation processor configured to adapt a bandwidth of the code word to at least part of a bandwidth of the original material item, and an encoder configured to combine the bandwidth adapted code word with a copy of the original material item. The probability of correctly detecting a code word is improved by combining the code word with a part of the bandwidth of the material item. As a result, if the material is transformed in some way the code word may still be detected.

Abstract: An encoding data processor generates a video material item marked copy by representing a payload data word as a code word and embedding the code word into a copy of the video material item. A preprocessor divides the payload word into plural parts, forms plural initial values from the plural parts, each initial value formed by adding parts of the payload data word to each initial value successively starting with the first part added to the first initial value, and adds the first and second to the second initial value so each subsequent initial value includes all parts of the payload data word of the previous initial values and a new part of the payload data word. An encryption processor receives each initial value and generates an encrypted data stream using a payload encryption key. A combiner combines the encrypted payload data word with the video material item.

Abstract: An encoding data processing apparatus generates a video material item marked copy by embedding a payload data word into the video material item. The video material item includes plural video frames. A code word generator generates a water mark code word from the payload data word and reads data representing the water mark code word into a shuffle data store. A shuffle processor generates pseudo randomly at least one address within an address space of the shuffle data store for each video frame and reads data representing part or parts of the water mark code word out from the data store at locations identified by the pseudo randomly generated address. A data embedding processor receives the video material item and embeds the data representing the part or parts of the water mark code word read out from the shuffle data store for each frame into a corresponding frame of the video material item.

Abstract: According to the present invention there is provided an encoding data processing apparatus for generating a marked copy of an item of material by introducing code words into a copy of the material item. The code words are arranged to identify a data word from a set of data words having at least two fields. The apparatus comprises a code word generator operable to generate at least two code words having a plurality of code word coefficients, each of the code words being independently generated from a different code word seed, and an encoding processor operable to combine the code word coefficients with the material item. One of the code words is selected from a first set in dependence upon a value of a first of the data fields and one of the code words is selected from a second set in dependence upon a value of a second of the data fields. The values of the first data field are associated with the first set of code words and values of the second data field are associated with the second set of code words, the second set of code words being selected in dependence upon the value of the first data field. By arranging for a value of a second or subsequent data field to be selected in dependence upon a value of the first or a previous data field, then a detecting complexity for unambiguously identifying the data word can be substantially reduced.

Abstract: A recording system for applying access control processing to input data content and for recording access-controlled data content on a computer readable storage medium. The recording system includes an encryption apparatus for encrypting portions of the input data content and an access control memory device which securely stores information from which a private key of a public key/private key pair associated with a data content recording user or user group is derivable. The encryption apparatus and the access control memory device co-operate to provide access control data including content recorder access control data and default access control data. The default content access control data provides the same level of access to the input data content as the level of access available to the data content recording user/user group. A recorder is provided for recording the encrypted input data content and the content access control data on the computer readable storage medium.

Abstract: An audio/video generation apparatus comprises an audio and/or video generation device operable to generate audio and/or video material, and a metadata generation processor. The metadata generation processor is operable to generate metadata describing the content and/or attributes of the audio/video material. The metadata generation processor is operable to generate a reference value providing a quasi-unique reference to the audio/video material with a reduced amount of data with respect to the audio/video material itself, the reference value being generated from data values representing the audio/video material in accordance with a predetermined relationship. The quasi-unique reference may be stored in association with the metadata describing the audio/video material from which the quasi-unique reference was generated.Generating a quasi-unique reference from the information material provides a facility for identifying the audio/video material. In one embodiment the quasi-unique reference is a hash value. The hash value provides a quasi-unique reference, which can be efficiently searched in order to identify, the audio/video material. Accordingly, metadata, which describes the content or attributes of the audio/video material, may be uniquely or quasi uniquely associated with the information material.

Abstract: A water marking system generates a water marked image frame for conveying a payload data word by combining at least one image frame with a two-dimensional water mark pattern. The water mark pattern includes plural regions each associated with one of symbols of the payload data word. Each region includes a two dimensional water mark block selected from a predetermined set of possible water mark blocks to represent the value of the payload data symbol associated with that region. A detecting data processing apparatus detects the payload data from a received water marked image frame, which has been encoded by utilizing a block match prior probability calculator operable to correlate each region of the water marked image frame with each of the water mark blocks from the set of water marked blocks) to form for each region a set of probability surfaces.
