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: This program separates the bits of a grayscale image showing the levels of each bit. The final reconstructed image with the 8 levels of gray scale image to check for loss of data and also shows the image with the four most significant bits. Dialogue is displayed in the matlab command window whether or not there is total reconstruction. Created by Oswaldo Angulo Vasquez - 2008 Platform: |

Description: 最不 重 要 位(LSB)方法DO是将秘密数据(水印数据)嵌入到载体数据中最简单的一种方法，它是在时域里隐藏数据。任何的秘密数据都可以看作是一串二进制位流，而音频文件的每一个采样数据也是以二进制数来表示。这样，可以将部分采样值的最不重要位用代表秘密数据的二进制位替换掉，以达到在音频信号中嵌入秘密数据的目的。-The most significant bits (LSB) method of DO is the secret data (watermark data) embedded into the data in the simplest way, which is hidden data in the time domain. Any secret data can be viewed as a string of binary bit stream, and audio files of data for each sample is expressed in binary numbers. This value can be part of the sample with the least bit representative of the secret bits of data and replace the audio signal to achieve the purpose of embedding the secret data. Platform: |

Description: The block maps each integer value (or stored integer when you use a fixed point input) to a group of M bits, using the selection for the Output bit order to determine the most significant bit. The resulting output vector length is M times the input vector length.-The block maps each integer value (or stored integer when you use a fixed point input) to a group of M bits, using the selection for the Output bit order to determine the most significant bit.
