    摘要： Methods, devices and computer program products enable embedding and extraction of multiple watermark messages in a coordinated fashion to improve watermark transparency, robustness against impairments, security, and computational complexity of embedding and extraction of watermarks. Coordinated watermark embedding and extraction operations take advantage of a pre-defined relationship between the symbols of two watermark messages. The improved aspects of the watermarking system provide significant value to content owners, content distributors, and consumers at a small incremental cost.

    摘要： Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. These operations can be conducted by one or more trusted devices that reside in a networked environment. Real-time access to a content can also be facilitated by utilizing existing watermark extraction records. To facilitate real-time access to the content, the extraction records may contain segmented authentication information that correspond to particular segments of the content that is being accessed. Additionally, or alternatively, new watermark extraction operations can be conducted in real-time to produce new watermark extraction records.

    摘要： Methods are provided for embedding auxiliary information in a host content signal which reduce the memory, bandwidth and computational complexity of the embedding and transmission systems. In one embodiment, a first reduced-scale signal is produced which corresponds to the host content embedded with a first logical value and producing a second reduced-scale signal corresponding to the host content embedded with a second logical value. A first set of segments from the first reduced-scale signal may be combined with a second set of segments from the second reduced-scale signal in a pre-defined manner to produce a composite embedded host content. Thus the storage and transmission requirements of the watermarking system are reduced to having to deal with only the original content plus two reduced-scale signals.

    摘要： Methods for adapting the operation of a system in response to the detection of embedded watermarks from a digital host content are provided. A digital host content is received and examined for the presence of watermarks. In response to the detection of embedded watermarks and in accordance with the value, type, density or spacing of the detected watermarks, one or more system reactions may take place. These reactions include conditionally allowing the system to resume its normal operation, prohibiting the system from resuming its normal operation, degrading the quality of the digital host content or changing the security status of the digital host content. In response to the extraction of weak watermarks that do not meet the desired system requirements, the extraction operation may be modified or extended to enable the detection of strong watermarks.

    摘要： A system for using a watermark embedded in an audio signal to remotely control a device. Various devices such as toys, computers, and appliances, equipped with an appropriate detector, detect the hidden signals, which can trigger an action, or change a state of the device. The watermarks can be used with a “time gate” device, where detection of the watermark opens a time interval within which a user is allowed to perform an action, such as pressing a button, typing in an answer, turning a key in a lock, etc. To prevent fraudulent activation of a time gate, the time gate device can be configured to react only to watermarks coming from live broadcasts, and not from replays from tapes or other storage devices. In another feature, robustness of the watermark is improved, e.g., for acoustic propagation channels, by shifting the detection time of the watermark based on a measured bit error count of the watermark. Furthermore, the watermark may be inserted before the desired action along with corresponding offset information if the audio signal is not suitable at the time of the action.

    摘要： Apparatus and methods are provided for encoding, storing and decoding auxiliary information on an analog source signal in a way which has minimal impact on the human perception of the source information when the source signal is applied to an appropriate output device, such as a speaker or a display monitor. The autocorrelation function of a host signal is modulated according to the value of an auxiliary information signal by adding a host modifying signal to the host signal. The auxiliary signal is decoded by generating the autocorrelation function of the encoded signal and extracting the auxiliary signal according to well-known signal extraction techniques.

    摘要： Methods, devices and computer program products facilitate conditional access to a content embedded with watermarks. For such a content, when copy control rules associated with an embedded watermark message prohibits unconditional access to the content, it is determined whether or not an exception to the copy control rules exists, and if an exception to the copy control rules exists, the content is conditionally accessed. Additional watermark messages can be extracted while the content is being conditionally accessed, and based on the additionally extracted watermark messages, it is verified that conditional access to the content has been fulfilled.
