Application of Chaos Theory in Information Detection

According to the characteristics of chaos system,three forms of chaos-based information detection technique are summarized.The first is using the sensitive to initial value and ergodic of chaos system,constructing chaos detecting system. The second is,presuming bac kground signals is chaotic, reconstructing phase space of the bac kground signals,then detecting useful signals from chaos bac kground signals. The third is,adding the signals detected to the parameters of the chaos system,using non-equilibrium phase transition of chaos system sensitive to system parameters and immunity to noise,detecting weak signals from strong noise.Finally,the peculiarity and the future of the chaos used in information testing are discussed.
