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 de-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。这可以以类似的方式在可能在客户端设备中的第二计算设备（16）中进行。客户端设备使用作为加密表（6）的修改（即加水印）版本的解密表（8）。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）之间的失配导致去信号（14）具有嵌入的水印。

摘要： Disclosed are a method and a system for secure watermark embedding in a server-client configuration (60,70). The method comprises encrypting (210) the data signal (x) and generating (240) a decryption key wherein a watermark (Wi) is included. The client decrypts (420) the encrypted data signal in order to obtain a watermarked data signal (xw). In accordance with the invention, the encryption mechanism and decryption key are made dependent on a perceptual mask (m1,m2) so as eventually make the embedded watermark more robust.

摘要： A lossless, reversible data embedding technique uses a generalization of least-significant-bit modification. The portions of the signal that are susceptible to embedding distortion are compressed and sent as part of the embedded payload. A prediction-based conditional entropy coder uses unaltered portions of the host signal to improve lossless data capacity.

摘要： Client terminals report an easy-to-calculate identifier such as the Internet URL or a cryptographic hash of the content to a server. The server collects and counts the reported identifiers so as to obtain preliminary statistics. By aggregating these reported identifiers into the preliminary statistics, identifiers are revealed that are likely popular content. The server selects one or more identifiers from the preliminary statistics and makes these available to at least a subset of clients. The clients that obtain these one or more identifiers then access content and compute the easy-to-calculate identifiers as usual. If the computed identifier matches one of the identifiers obtained from the server, the client will additionally extract a watermarked identifier or compute a digital fingerprint of the content in question and report this to the server. The server then uses the received identifier or fingerprint to create final statistics by aggregating the preliminary statistics.

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.

摘要： The invention relates to a method of searching for a watermark in a data signal, and to a watermark detector, such as a copy-control watermark detector. The search is conducted in order to find a watermark in content which possibly has been attacked and/or altered. The search is conducted by the steps of determining or setting a search space for the data signal, selecting a subspace of the search space, and searching for the presence of the watermark in the subspace. The subspace may be selected from a multitude of regions, the selection e.g. being based on a deterministic or probabilistic function.

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.
