Abstract: A computer is provided with an application and a printer driver. A user of the computer generates image data using the application. When the image data is for a plurality of pages, the user selects a desired watermark for each of the plurality of pages. The printer driver converts the image data into print data, and combines selected watermarks with the print data for corresponding pages, thereby generating updated print data. The updated print data is output as a single print job to the printer. The printer executes printing operations based on the print job so as to an image on a plurality of pages each formed with a corresponding watermark.

Abstract: Methods and apparatus for embedding a watermark in a multimedia signal and detecting the watermark, are described. The method comprises the steps of generating a watermark signal comprising a first sequence of values and a second sequence of values; obtaining a first signal portion corresponding to a first channel and a second signal portion corresponding to a second channel from the multimedia signal, said channels being significantly independent; generating a first host modifying signal as a mixture of the first signal portion and the first sequence; generating a second host modifying signal as a mixture of the second signal portion and the second sequence; and generating a watermarked multimedia signal by combining scaled versions of the host modifying signals with the multimedia signal.

Abstract: A data processing apparatus is operable to identify one of a plurality of code words present in a watermarked version of a material item. The marked version is formed by combining each of a plurality of parts of a code word with one of a plurality of units from which the material item is comprised. The apparatus comprises a recovery processor operable to recover at least one part of the code word from a corresponding unit of the marked material item, and a correlator. The correlator is operable to generate for the marked material unit, a dependent correlation value for the part of the code word recovered from the material unit and the corresponding part of at least one of the re-generated code words from the set. A detector is operable to determine whether at least one of the code words is present in the marked material item from the dependent correlation value for the part of the code word exceeding a predetermined threshold. The data processor may detect the presence of the code word with improved probability, in particular when parts of the material have been corrupted.

Abstract: An electronic watermark data insertion apparatus comprises an insertion information memory (39) for preliminarily storing insertion information for designating electronic watermark data to be inserted block by block and an electronic watermark data insertion unit (33) for inserting, on the basis of the insertion information, the designated electronic watermark data from an electronic watermark data table (37) in a quantized image block by block. An electronic watermark data detection apparatus comprises an electronic watermark date extracting unit (45) for extracting the image data having a biased frequency region projecting in dependency on the inserted electronic watermark data block by block and an electronic watermark data detection unit (50) for calculating a statistical similarity between the extracted data and the electronic watermark data stored in an electronic watermark data table (48). An electronic watermark data accumulator (51) accumulates the statistical similarity for a predetermined time interval to produce an accumulated addition result which is reset after the elapse of the predetermined time interval or when the accumulated addition result exceeds the a predetermined threshold value. A determining unit (52) determines that the electronic watermark data is detected when the accumulated addition result exceeds the predetermined threshold value.

Abstract: Techniques for secure distribution of digital representations that combine encryption and watermarking. When a user at a client desires to download a digital representation, the user makes a request to a server for the digital representation, which encrypts the digital representation using a first key and downloads the encrypted digital representation to the user. Before the user performs any operation on the decrypted digital representation, a secret fingerprint watermark identifying the user is added to the digital representation. The fingerprint watermark is added either at the server or at the client and a copy of the fingerprinted digital representation is kept at the server. If the user makes an impermissible use of the digital representation, the secret fingerprint watermark can be used to identify the user. The request made by the user indicates the type of use that the user wished to make of the digital representation. If the use involves storage of the digital representation at the client, the server provides a second key that the client employs to encrypt the digital representation. If the user has permission to do so, the user may modify the digital representation and return the modified digital representation to the server for further distribution. In this case, the second key is used to encrypt the digital representation when it is sent to the server. The second key also serves as the user identification in the fingerprint watermark. If the user loses the second key, it can be recovered from the copy of the fingerprinted digital representation kept at the server. The first and second keys and any decrypted copy of the digital representation are kept in secure storage in the client.

Abstract translation: 用于安全分发加密和水印的数字表示的技术。 当客户端的用户希望下载数字表示时，用户向数字表示服务器发出请求，数字表示使用第一密钥加密数字表示，并将加密的数字表示下载给用户。 在用户对解密的数字表示执行任何操作之前，将标识用户的秘密指纹水印添加到数字表示。 指纹水印在服务器或客户机中被添加，并且指纹数字表示的副本被保存在服务器上。 如果用户不允许使用数字表示，则可以使用秘密指纹水印来识别用户。 由用户作出的请求指示用户希望进行数字表示的使用类型。 如果使用涉及在客户端处存储数字表示，则服务器提供客户端用于加密数字表示的第二密钥。 如果用户具有这样做的权限，则用户可以修改数字表示并将修改的数字表示返回到服务器以进一步分发。 在这种情况下，第二个键用于在发送到服务器时对数字表示进行加密。 第二个键也用作指纹水印中的用户标识。 如果用户丢失第二个密钥，则可以从保存在服务器上的指纹数字表示的副本中恢复。 数字表示的第一个和第二个键和任何解密的副本都保存在客户端的安全存储中。

Abstract: A method and arrangement for embedding and detecting a watermark in an information signal is disclosed. The embedded watermark (Wi) is selected (13) from a plurality of watermarks (W1..WN) in dependence upon a property P of the signal. An example of such a property is the distribution of luminance values of the current video image as calculated by an analysis circuit (12). The corresponding watermark detector performs the same operation: the watermark being looked for depends on the same signal property. It is achieved with the invention that the embedded watermark changes from time to time as a function of the information signal content, so that it cannot easily be hacked.

Abstract: A watermarking procedure wherein each of a set of copies of the work has a slightly-modified form of a "baseline" watermark that is placed within a critical region of the data. The slight variations in the watermarks, however, are not perceptually visible and do not interfere with the work. If multiple persons collude to attempt to create an "illicit" copy of the work (i.e., a copy without a watermark), however, at least one of the modified watermarks is present in the copy, thereby identifying both the illicit copy and the copier.
