定向测量与加权算法的信息隐藏技术
Information Hiding Technology Based on Directional Measurement and Weighted Algorithm
摘要
Abstract
The observation values of the compressed sensing (compressed sensing, CS) technique exist certain redundancy, it can be used to write secret information. In order to improve hiding algorithm of perceptual and computational speed, this paper presents a directional measurement algorithm, which only let the important part of the carrier image sparse and measure, while select hide location by using the idea of weighted algorithm and provide the information hiding and extraction method. Simulation result shows, the method in imperceptibility and calculation time losses are superior to the traditional algorithm and has certain robustness and extraction resistance.关键词
