Because neural network is much more advanced,compared with the traditional pattern recognition,so we introduce the method to the training of reservoir data.

Secure data hiding algorithm based on simulated annealing;

Complementary matrix–based algorithm for data hiding;

A method of data hiding of high capacity based on the information divided-storage using integer wavelet transform

With analyzing the characteristics of media data and the technique of information hiding algorithm, an approach to achieve this aim by data embedding is proposed, in which the key is transmitted and managed on application layer, and is embedded into media stream.

It introduces the principle and mechanism of the model, and discusses the data mines and influence domain of the model and the relationship between them.

But as the presence of some masked datain system-level data,we have to calculate the failure probability of components conditioned on system-level testi.
