A secure software copy avoidance system using chaos synchronization

摘要

An object of the present invention is to provide a software piracy prevention system using the chaos principle.; According to the present invention, there is provided a software piracy prevention system comprising a computer side of the encryption module and a decryption module of the user side; Encryption of the computer-side module, the first chaotic system of claim 1, a white noise generator generating white noise, receiving said first white noise input to the white noise generated by the generator for generating a chaos signal, and in the first chaotic system by mixing the information signal to be generated chaotic signal and encryption comprises an encryption of generating a scrambled signal; Of the user side decryption module, generated by the second chaotic system, and the second chaotic system of claim 2, the white noise generator for generating a white noise, receiving said second white noise input to the white noise generated by the generator for generating a chaotic signal the using the chaos signal, a software piracy prevention system, characterized in that made in comprising a decoding for extracting from the encoded information signal with a chaotic signal and the information signal is mixed only the information signal is provided.
