摘要： This disclosure describes methods for using embedded auxiliary signals in documents for copy detection and other applications. In on application, the auxiliary signal is formed as an array of elements selected from a set of print structures with properties that change differently in response to copy operations. These changes in properties of the print structures that carry the embedded auxiliary signal are automatically detectable. For example, the changes make the embedded auxiliary signal more or less detectable. The extent to which the auxiliary data is detected forms a detection metric used in combination with one or more other metrics to differentiate copies from originals. Examples of sets of properties of the print structures that change differently in response to copy operations include sets of colors (including different types of inks), sets of screens or dot structures that have varying dot gain, sets of structures with different aliasing effects, etc. Robust and fragile watermarks are used in Image Replacement Documents for a variety of applications. Digital watermarks act as on-board mediators in authentication of a variety of printed documents. Finally, digital watermarks are used to help manage quality of the scanners used in imaging systems.
摘要翻译：本公开描述了在用于复制检测和其他应用的文档中使用嵌入式辅助信号的方法。在应用中，辅助信号被形成为从一组打印结构中选择的元素的阵列，其具有响应于复制操作而改变的属性。携带嵌入式辅助信号的打印结构的这些属性变化可以自动检测。例如，这些改变使得嵌入式辅助信号或多或少被检测出来。检测辅助数据的程度形成与一个或多个其他度量结合使用的检测度量，以区分副本与原件。对于复制操作而改变不同的打印结构的属性集合的示例包括具有不同的点增益的颜色（包括不同类型的墨水），屏幕或点结构的集合，具有不同混叠效果的结构集合等图像替换文档中使用了强大而脆弱的水印，用于各种应用。数字水印作为各种印刷文件认证中的板载介质。最后，数字水印用于帮助管理成像系统中使用的扫描仪的质量。

摘要： A method for tracking media signals in multimedia content is provided by uniquely identifying the multimedia content with a digital watermark identifier. A video channel is preferably embedded with a first watermark identifier. The first identifier uniquely identifies the multimedia content or the content family. A second digital watermark is embedded in an audio channel of the multimedia content. The second digital watermark uniquely identifies a user or user device. When the multimedia content is found in an unauthorized or unexpected channel, the content can be traced back to its misappropriating source via the user identifier.

摘要： The present invention relates to steganographic encoding for multimedia content. In one combination, a method is provided including: encoding first information in a first component of a multimedia signal, the first component comprising audio, the first information being encoded though subtle changes to data representing the first component; encoding second information in a second component of the multimedia signal, the second component comprising video, the first information being encoded though subtle changes to data representing the first component, the first information and the second information are associated. Of course, other combinations are provided as well.

摘要： The presently claimed invention relates generally to steganography and fingerprinting or hashing. In one embodiment, a method includes: obtaining a first set of plural-bit data, the first set of plural-bit data corresponding to at least a portion of steganographically encoded data in a media signal in the form of a digital watermark; obtaining a second set of plural-bit data, the second set of pural-bit data corresponding to a fingerprint or hash of the media signal. THe fingerprint or hash includes a reduced-bit representation of the media signal, and the first set of plural-bit data is not dependent on information in the second set of plural-bit data. The method further includes carrying out a first action associated with the first set of plural-bit data; and carrying out a second action associated with the second set of plural-bit data. Other embodiments are described and claimed as well.

摘要： Identification of media content, such as audio, can be performed through use of watermarking or fingerprinting (aka content signature) technologies. Aspects of these technologies may be combined to advantageous effect. For example, in dealing with the problem of fingerprint errors arising from object distortion, operations known from digital watermarking systems can be employed.
