The Design And Implementation Of An Intelligence Transfer System Based On Information Hiding

With the constantly in-depth advance in and application of information technology, information security has been paid more and more attention to by each country in the world. Presently, it is advancing towards two directions. One's core is modern cryptology, which protects the information by encrypting its content. The other's core is Information Hiding, which hide the content of information. Therefore, Information Hiding has caused a wide attention among military apartments across the world, for its better hiding performance over cryptology.The whole thesis is made up of two sections: 1. The study of Information Hiding technologies. In this section, we combined LSB algorithm and wavelets transform domain algorithm, then proposed a high-capability information hiding algorithm based on integer wavelets transform. Compared with LSB algorithm by experiments, this one reached higher PSNR value. 2. The design and implementation of an intelligence transfer system based on information hiding technologies. This thesis detailed the requirements of this system, designed the framework and solved all key issues of specific modules.This system gained a high transmision ratio and rate during the three experiments in campus network, and has been proved to be valuable for improving security and timeliness of intelligence transfer applications.
