Description: 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。 -LSB of the image-based data encryption to hide the image composition algorithm procedure is nothing more than some number of bytes or string composed of string, however, one byte for each data bit is not an important degree of the same, and two adjacent words section, usually only low level is not the same. For example: 00100110 and 00100111 represent the gradient of two different degrees of red, but on the human eye is not out to tell. Least significant bit LSB algorithm, is to take advantage of this point, to achieve image compression, or digital watermark feature. Platform: |

Description: Firstly, research on robust image watermarking. A digital watermarking scheme based on wavelet transform was proposed. It realizes the watermarking extract without the original image using 64×64×8 bit gray image as the watermark signal. In order to enhancing the security of the watermark, we employ an encryption technology based on chaos and bit plan. Simulation results show that our scheme have good invisibility and can survive low-quality JPEG compression, median filtering and so on. In addition, the analysis of the extracted watermark can help us to detect and localize tampers.-Firstly, research on robust image watermarking.
