数字水印技术的基本概念

md5的加密函数 iis下运行； 用法: 1：页面包含该文件 2：调用方法MD5(sMessage,stype) 例dim md_=md5("admin"，32) *注：最高32位。-md5 encryption function running under iis Usage: 1: page 2 of the document contains: call method MD5 (sMessage, stype) were dim md_ = md5 ( " admin" , 32)* Note: maximum 32.

一个DES加密算法的实现-a DES encryption algorithm implementation

以前发的那个只实现了SHA-1, 现在补全了, sha-160, sha-224, sha-256, sha-384, sha-512-Previously issued only to realize that the SHA-1, is now a complete, sha-160, sha-224, sha-256, sha-384, sha-512

基于unix下的RSA加密实例分析-under the RSA encryption Case Analysis

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection

是我设计的在DSB中隐藏语音的例子. 用ELANIX公司的SYSTEMVIEW打开运行. 其掩护信号和隐藏信号输入输出端均需设置语音源文件,比如自己录制的声音.-I designed the DSB concealed voice example. ELANIX company with the SYSTEMVI EW open operation. their cover and concealment signal input and output signals required to set up voice source, For example, recording their voices.

基于JAVA语言的MD5编程，可以进行实验讲解，有输入输出示范-based on MD5 Java programming language, can conduct experiments to explain, input-output model
