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.
摘要翻译：提供了用于将辅助信息嵌入主机内容信号中的方法，其减少嵌入和传输系统的存储器，带宽和计算复杂性。在一个实施例中，产生对应于嵌入有第一逻辑值的主机内容并产生与嵌入第二逻辑值的主机内容相对应的第二缩小尺度信号的第一缩小尺度信号。来自第一缩小尺度信号的第一组片段可以与来自第二缩小尺度信号的第二组片段以预定义的方式组合以产生复合嵌入式主机内容。因此，水印系统的存储和传输要求被减少到必须仅处理原始内容加上两个缩小尺度的信号。

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.
摘要翻译：一种使用嵌入在音频信号中的水印远程控制设备的系统。配备有适当检测器的各种装置，例如玩具，计算机和电器，可以检测可触发动作的隐藏信号或改变装置的状态。水印可以与“时间门”设备一起使用，其中水印的检测打开用户被允许执行动作的时间间隔，诸如按下按钮，输入答案，将键转动到锁定中等等。为了防止时间门的欺骗性激活，时间门装置可以被配置为仅响应来自实时广播的水印，而不是来自磁带或其他存储设备的重放。在另一个特征中，通过基于水印的测量比特误差计数来移动水印的检测时间，改善了水印的鲁棒性，例如对于声传播信道。此外，如果音频信号在动作时不适合，则可以在期望的动作之前插入水印以及对应的偏移信息。

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： Apparatus and methods are provided for embedding or embedding digital data into an analog host or cover signal. A distributed signal feature of the cover signal in a particular domain (time, frequency or space) is calculated and compared with a set of predefined quantization values corresponding to an information symbol to be encoded. The amount of change required to modify the signal feature to the determined target quantization value is calculated and the cover signal is modified accordingly to so change the feature value over a predefined interval. Information symbols are extracted by the opposite process. In one embodiment, the predefined value is a short term auto correlation value of the cover signal.

摘要： A system for determining the amount of processing that has been applied to watermarked signal. A steganographic signal is provided that includes an original signal and an embedded fragile watermark. The fragile watermark is characterized by a low energy and a high redundancy in comparison to a robust watermark. The steganographic signal is communicated over a distribution channel to a decoder. At the decoder, a measure of a presence of the fragile watermark in the acquired steganographic signal is provided, along with an estimate of the fragility profile of the fragile watermark for this particular original signal. Based on these factors, a estimate is made of the amount of processing that the steganographic signal has undergone. This processing can include, for example, A/D and D/A conversions, resampling, band-limiting, perceptual compression/decompression, etc. Optionally, the fragility profile is derived prior to the distribution of the content and communicated by the steganographic signal for recovery by the decoder. Furthermore, a robust watermark may be provided in the steganographic signal that, e.g., designates the presence of the fragile watermark to a decoder.
摘要翻译：一种用于确定已应用于水印信号的处理量的系统。提供了包含原始信号和嵌入的脆弱水印的隐写信号。与鲁棒水印相比，脆弱水印的特征在于低能量和高冗余度。隐写信号通过分发信道传送到解码器。在解码器中，提供了在所获取的隐写信号中存在脆弱水印的度量以及用于该特定原始信号的脆弱水印的脆弱性分布的估计。基于这些因素，估计隐身信号已经经历的处理量。该处理可以包括例如A / D和D / A转换，重采样，频带限制，感知压缩/解压缩等。可选地，脆弱性分布是在内容分发之前导出的并通过隐写信号传送的用于由解码器恢复。此外，可以在隐写信号中提供鲁棒水印，例如，将脆弱水印的存在指定给解码器。

摘要： Methods, devices and computer program products for enabling secure and efficient extraction of embedded watermarks from digital host content are provided. Upon the reception of a multi-channel digital host content with embedded watermarks, a subset of the received channels are selected and combined together to form a composite content. The composite content is then examined to recover embedded watermarks. The particular subset of channels can be selected according to a probability value. Further, a set of new channels can be selected and combined after a particular time interval has elapsed. The number of selected channels can also be varied each time a new selection is made.
