摘要： A client device for use in a system having a server, the client device including: a receiving device configured to receive information material from the server, the information material containing a reversible modification providing a visually perceptible disturbing effect having been applied to the information material by using an invertible algorithm which uses values generated from one or more keys, and to receive identifying information that distinguishes the information material from other information material available from the server and condition information which defines a predetermined condition that should be met in order for the reversible modification to be reversed.

摘要： A system for watermarking and transferring watermarked material comprises a transaction server, first and second clients, first apparatus for applying a perceptible watermark to the material and second apparatus for removing the watermark. The server, clients and first and second apparatus are linked by one or more communications networks. The system is arranged to implement the steps of: transferring from the transaction server to the first apparatus (i) data for creating a watermark, the creating data including (a) data defining an invertible algorithm and (b) data for creating at least one security key associated with the algorithm and (ii) data for creating a material identifier; using the said first apparatus to apply a material identifier to the material and applying a watermark to the material, using the said creating data; transferring from the first client to the transaction server the said material identifier and data for inverting the algorithm including the said at least one key; transferring the watermarked material to the second apparatus; deriving the said material identifier from the material; transferring the identifier from the second client to the transaction server; subject to predetermined conditions being satisfied, transferring from the transaction server to the second apparatus watermark removal data associated with the said material identifier, the removal data including at least one key and data defining an algorithm for removing the watermark in conjunction with the key; and using the second apparatus to remove the watermark using the said removal data.

摘要： In a peer-to-peer network of peers 10 which are interconnected for sharing content data, the peers 10 store content files of content data in a file structure comprising a plurality of content folders 21, 22, 23, each content folder 21, 22, 23 containing any number of content files 24 of related content data, and a description file 26 containing both unique identification information and descriptive information in XML format describing the content file or files 24 stored in the same content folder 21. Requesting peers 10 transmit search query messages which specify search criteria for passage through the network. Peers 10 receiving a search query message compare the search criteria with the descriptive information contained in the description files in each of their plurality of content folders 21, 22, 23, and in the event of there being a matching content folder transmit a hit message including the identification information to identify the matching content folder for passage back through the network to the respective requesting peer 10.
