摘要： Disclosed is a method for identifying content within a received information signal. The method comprises receiving (S6) an information signal; generating (S8) a first data set by selecting a sub-set of data (7) using filter data; and processing (S9) said information signal with reference to said first data set to determine whether said information signal comprises particular content. Advantageously, the method further comprises processing (S 12) the information signal with reference to a second data set (6) to determine whether said information signal comprises particular content. The invention allows content sharing sites such as YouTube to check whether uploaded files violate copyright rules in case the upload includes contents that was previously downloaded by the client. By keeping a list of contents that clients have downloaded, the server has an indication of a subset of contents that will likely be included in the next upload by the same client. As this subset is relatively small, a finer fingerprint resolution may be applied to this subset.
摘要翻译：公开了一种用于识别接收的信息信号内的内容的方法。该方法包括：接收（S6）信息信号; 通过使用过滤数据选择数据（7）的子集来生成（S8）第一数据集; 以及参考所述第一数据集处理（S9）所述信息信号，以确定所述信息信号是否包含特定内容。有利地，该方法还包括参考第二数据集（6）处理（S12）信息信号，以确定所述信息信号是否包含特定内容。本发明允许诸如YouTube之类的内容共享站点检查上传的文件是否违反版权规则，以防上载包含客户端先前下载的内容。通过保留客户端下载的内容列表，服务器具有可能被同一客户端下次上传的内容的子集的指示。由于该子集相对较小，因此可以将更精细的指纹分辨率应用于该子集。

摘要： A method of watermarking a video signal comprises encoding the video signal using a plurality of encoding parameters and, during said encoding, varying a value of at least a selected one of said parameters with time according to a watermarking pattern, the selected parameter being a parameter that affects at least a type or an amount of information lost in encoding the signal. An example of a suitable parameter is a quantization factor used to encode the video signal. The quantization factor may correspond to a particular coefficient of a transform used to encode the video signal, and may, for example, be an element of a quantization matrix corresponding to a particular coefficient in a block DCT transform. The method may conveniently be implemented in devices with limited processing resources, such as existing DVRs, by means of a software update, yet enables those devices to imprint a signal they encode with a robust watermark which may survive subsequent decompression and recompression. In another aspect, a video signal is watermarked by modifying a magnitude of at least one selected non-dc spatial frequency component in a manner which varies with time according to a watermarking pattern. Corresponding watermark detection methods and watermarking devices are disclosed.
摘要翻译：一种对视频信号加水印的方法包括使用多个编码参数对视频信号进行编码，并且在所述编码期间根据水印使时间上的至少一个所选参数的值随时间变化模式，所选参数是至少影响编码信号时丢失的信息的类型或量的参数。合适参数的例子是用于编码视频信号的量化因子。量化因子可以对应于用于编码视频信号的变换的特定系数，并且可以例如是对应于块DCT变换中的特定系数的量化矩阵的元素。该方法可以通过软件更新方便地在具有有限处理资源的设备（例如现有DVR）中实现，并且使得这些设备能够用可以在后续解压缩和再压缩中生存的鲁棒水印来压印它们编码的信号。在另一方面，通过根据水印图案以随时间变化的方式修改至少一个选择的非dc空间频率分量的幅度来对视频信号加水印。公开了相应的水印检测方法和水印设备。

摘要： The invention relates to embedding auxiliary data in the form of a multibit payload in a host signal, and encrypting the associated detection key. Moreover, the invention relates to extracting the auxiliary data in the form of the multibit payload from a data signal. Auxiliary data is embedded in a host signal by the following steps. First a reference watermark is provided, subsequently an encrypted detection key associated only with the reference watermark is generated. The encrypted detection key may be a scrambled version of the watermark. In a further step, the multibit watermark is generated and a multibit payload is encoded into the reference watermark. Finally, the multibit watermark is embedded into the host signal.

摘要： The present invention relates to a method and a unit for securely providing watermarking data for watermarking a content. Watermarking data consists of cipher texts that are generated based on the content, a watermark and a number of encryption parameters. The invention also provides a method and a unit for securely watermarking a content at an untrusted location, such as at the location of a content consumer. The watermarking unit receives a number of cipher texts provided for instance by a watermarking data unit in accordance with the invention, and calculates the watermarked signal based on the cipher texts.

摘要： The invention relates to embedding a spread spectrum watermark in a data signal as well as to detection of the embedded watermark. A data signal (4) is encrypted (15) or received in the form of an encrypted data signal (9), the signal being encrypted by modifying (3) it in accordance with one or more entries of a look-up-table (2) in which an encryption table (6) is stored. The encryption is carried out by a first computing device (15) such as a server device. The watermark is actually embedded while decrypting (13) the signal. This takes place in a second computing device (16), possibly in a client device, in a similar manner. The client device employs a decryption table (8), which is a modified (i.e. watermarked) version of the encryption table (6). The decryption table may generated by the server and securely communicated to the client. The data signal is decrypted in accordance with entries of a look-up-table (12). The look-up-tables (2,12) in server and client are addressed by the same sequence of pointers generated by respective index generators (1). The mismatch between encryption table (6) and decryption table (8) causes the decrypted signal (14) to have an embedded watermark.
摘要翻译：本发明涉及在数据信号中嵌入扩频水印以及嵌入水印的检测。数据信号（4）被加密（15）或以加密数据信号（9）的形式接收，该信号通过根据查找表（的一个或多个条目）修改（3） 2），其中存储加密表（6）。加密由诸如服务器设备的第一计算设备（15）执行。在解密（13）信号时实际嵌入水印。这以类似的方式发生在可能在客户端设备中的第二计算设备（16）中。客户端设备采用解密表（8），其是加密表（6）的修改（即加水印）版本。解密表可以由服务器生成并且安全地传送给客户机。数据信号根据查找表（12）的条目解密。服务器和客户机中的查找表（2,12）由相应的索引生成器（1）生成的相同的指针序列进行寻址。加密表（6）与解密表（8）之间的不匹配导致解密信号（14）具有嵌入的水印。

摘要： The present invention relates to methods and apparatus for transfer of digital content. A method of transferring digital content from a first entity (60) to a second entity (70) includes a transfer control entity (50) transmitting a transmission key k 1 [n] to the first entity. The first entity applies the transmission key to digital content, to encrypt the digital content. The first entity transmits the encrypted digital content to the second entity. The transfer control entity transmits a receive key k 2 [n] for receipt by the second entity. The second entity applies the receive key to the encrypted digital content to generate decrypted data comprising the decrypted digital content embedded with a watermark w[n]. The transfer control entity transmits a degraded version w'[n] of the watermark to an entity for watermark detection.

摘要： The invention relates to extracting and embedding auxiliary data from and to a host signal. In an embodiment, the auxiliary data relates to remotely control of an application or a device, such as an interactive toy. Auxiliary data are extracted from a host signal, by periodically (32A-32C) with a predetermined first period searching a first section (33A-33C) of the host signal for a first watermark (34); and, upon detection of the first watermark, searching the host signal for a second watermark (35). In embodiments, information relating to timing and type of action to be performed by a remotely controlled device may be conveyed by the watermarks.
