基于LSB的图像中数据加密隐藏算法程序 图像的组成无非是一些字符串或者一些字节组成的字符串，然而，每一个字节数据位的重要度并不是一样的，两个相邻字节往往只有低位是不一样的。例如：00100110和00100111代表了两个不同渐变度的红色，但是就人眼是分辨不出来的。最低有效位LSB算法，就是利用这一点，达到图像压缩，或者数字水印的功能。 信息隐藏,即将信息嵌入某些载体,而使信息窃取者注意不到信息的存在。由于人眼的视觉的冗余及图像文件本身的数据量很大,数字图像文件是信息隐藏很好的载体,将需要保密的信… 包括的文件有： findtext.m, hidetext.m, main.bmp, new2.bmp, message.txt, output.txt, gui.fig, new.bmp, gui.asv, gui.p, secret.bmp, read me.txt, screenshot.bmp, screenshot.jpg-err

ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map - In this paper, a novel block digital image encryp- tion scheme based on a chaotic coupled map lattices (CML) is reported. Within this scheme, an original image is decomposed into sub-blocks with a given size, and an external secret key with 192-bit is used and mapped to the system parameters, which are employed to generate a spatiotemporal chaotic binary sequence matrix to encrypt the block original image. Besides, the former sub-block encrypted result will be acted as a feedback to the following sub-block encryption proc- ess. The proposed scheme is described in detail, along with the security analyses such as key space analysis, sensitivity analysis, information entropy analysis and correlation coefficients analysis of adjacent pixels. The computer simulation results indicate that the suggested image encryption scheme has some properties desir- able in a good security
