    Abstract: PROBLEM TO BE SOLVED: To embed or extract digitized information into/from analog host signal or cover signal having minimal affection on the perception of source information, relating with an apparatus for encoding and decoding information in analog signal.
    SOLUTION: An apparatus and a method for embedding digital data into an analog host signal or cover signal are provided. The feature of distributed signal of the cover signal in a specific definition region (time, frequency or space) is calculated, and compared with the assembly of prescribed quantized value corresponding to an information symbol to be encoded. The amount of change required to change the signal feature into the determined target quantized value is calculated and the cover signal is changed accordingly over the prescribed interval so as to change the feature value. The information symbol is extracted by an opposite process. In an embodiment, the prescribed value is a short term autocorrelation value of the cover signal.

    Abstract: Methods, devices, and computer program products facilitate the application of content usage rules based on watermarks that are embedded in a content. The required content screening operations, including watermark extraction and the application of content usage enforcement actions, are organized as separate tasks. These tasks can be conducted at different times by different devices. The watermark extraction results are stored in a secure location and can be accessed by other devices at different times. These operations can be conducted by one or more trusted devices that reside in a home network. The trustworthiness of the devices can be ascertained during a device authentication process. Further, certain device capabilities can be ascertained either as part of the device authentication process, or through additional communications between the devices.

    Abstract: Methods are provided for embedding auxiliary information in a host content signal which reduces the memory, bandwidth and computational complexity of the embedding and transmission systems, m one embodiment, a first reduced-scale signal is produced [figure 2, ref. Num "230"] which corresponds to the host content embedded with a first logical value [figure 2, ref. Num "220"] and producing a second reduced-scale signal [figure 2, ref. Num "235"] corresponding to the host content embedded with a second logical value [figure 2, ref. Num "225"]. 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 [figure 2, ref. Num "230"]. 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.

    Abstract: 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.

    Abstract: A system for using a watermark embedded in an audio signal to remotely control a device (290). Various devices such as toys, computers, and appliances, equipped with an appropriate detector (292), 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.

    Abstract translation: 一种用于使用嵌入在音频信号中的水印远程控制设备的系统（290）。 配备有适当的检测器（292）的诸如玩具，计算机和电器的各种装置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。

    Abstract: Methods and apparatus for embedding digital watermarks into a digital host content are provided. A digital host content is received, e.g., at a receiver or other device incorporating a receiver. One or more watermark embedding technologies is selected. Multiple embedding opportunities are identified within the host content. A subset of the identified embedding opportunities is selected. A multiplicity of digital watermarks are then embedded into the host content in accordance with the selected subset of embedding opportunities utilizing the one or more selected watermark embedding technologies. The selecting of the subset of embedding opportunities may be adapted to provide a desired tradeoff between levels of robustness, security, and transparency of the watermark. A plurality of watermarking embedding technologies may be selected and used in the embedding step.
