  • Patent number: 7106882
    Abstract: The invention provides methods, apparatus and systems for providing robustness relative to data compression and conversion for additional information embedded into digital content. Before predetermined additional information is embedded into digital content, the state following the embedding of additional information is set for the feature values that are used for the embedding of the additional information, so that the distribution of the feature values obtained following the embedding conforms to a predetermined function. Then, based on the setting contents, the feature values of the digital content are changed. In the information detection process, when the digital content in which the additional information is embedded is compressed, a predetermined distribution of the feature values of the digital content is employed to reproduce the distribution of the digital content feature values in the state preceding the conversion.

  • Patent number: 6983264
    Abstract: The present invention provides methods and apparatus to stably separate and extract an original signal from multiple signals by a few calculation steps when multiple signals have been observed in a mixed state. In an example embodiment, signals are separated by introducing a function having a monotonously increasing characteristic like an exponential type function as a cost function, and applying an adaptive algorithm that minimizes that cost function in terms of a signal separation matrix. Then, an error signal e(t) is calculated based on y(t) formed by this nonlinear function, the estimated separation matrix W(t?1) estimated at the previous cycle, and the observed signal x(t) at that time. Then, based on the calculated error signal e(t), the update of the separation matrix W(t) at that time is performed such that consideration weight is increased when estimation errors are large using the cost function having a monotonously increasing characteristic.
