一种基于LSB的图像信息隐藏算法
An image information hiding algorithm based on LSB
摘要
Abstract
The influence of compression algorithm and LSB algorithm on images are analyzed. It is found that the compres-sion results have block differences. So after lossy compression of image,the secret information hiding in the image also has differences of extraction effects in different blocks. With these differences , a new image information hiding algorithm is proposed,which embeds the secret information in blocks that have good anti-compression performance,so as to realize the space information hiding algorithm with anti-compression performance. The simulation results show that the proposed algorithm not only embeds and extracts information easily,but also has a certain resistance to JPEG and JPEG2000. The embedding capacity of the algorithm is large enough to meet the requirements of embedding small image in large image.关键词
