一种改进的DCT信息隐藏算法
A Sort of Improved Algorithm for DCT Information Hiding
摘要
Abstract
So far, the most researches about information hiding adopt the classical DTC algorithm and encode information by using chaotic algorithm and iterative algorithm to select embedding position, but the security of the method isn＇ t high. On this basis, the paper proposed an improved information hiding algorithm. First the algorithm exchanges the carrier and cryptograph, embeds the cryptograph into the carrier. The selecting processes of exchanging data and embedding position both use the thought of genetic algorithm, and display effect of the carrier doesn＇ t alter through exchanging data. Simulation experiment shows that the cryptograph extracted from the carrier encoded by the improved algorithm, and by traditional method will be messy code. The algorithm is effective in information hiding, and the security of cryptograph has been improved a lot.关键词
