The chaos sequence proliferation(CSP) algorithm is constructed to address the problem that the limited computational accuracy of computers can lead to periodicity in long chaotic sequences, making them unsuitable for encrypting objects with large amounts of data. By combining the Chaos-LSTM model and CSP algorithm, a geographic information encryption system is proposed. First, the Chaos-LSTM model is used to output chaotic sequences with high spectral entropy(SE) complexity. Then, a shorter chaotic sequence is selected and proliferated using the CSP algorithm to generate chaotic proliferation sequences that match the encrypted object;a randomness analysis is conducted and testing is performed on it. Finally, using geographic images as encryption objects, the chaotic proliferation sequence, along with the scrambling and diffusion algorithms, are combined to form the encryption system, which is implemented on the ZYNQ platform. The system's excellent confidentiality performance and scalability are proved by software testing and hardware experiments, making it suitable for the confidentiality peers of various encryption objects with outstanding application value.展开更多

There are two parts: creating and embedding the electronic watermark. The approach is to hide the watermark which is formed by chaos sequence used logistic algorithms into a color image, using the theory of visual sensitivity difference towards concolorous light. The other is the intellectualizing electronic watermark test device, which contains charge coupled device array and digital signal processing processor. This low cost test device together with electronic watermark printed on press products formed a sophisticated technical system of anti-imitation on presswork. The method and application system have been tested and the Anti-imitation effect is good.展开更多
