Description: matlab 源码,基于小波变换的语音信息隐藏的实现,对原始语音信息和水印信息都经过三层小波分解处理后,将水印信息的低频信号嵌入原始语音信号的部分高频信号部分实现隐藏.源代码不仅给出隐藏过程,并且给出的在随机噪声,重采样,信息压缩情况下的抗攻击特性.源代码清晰有注释-matlab source code, based on wavelet transform voice messages hidden realize, the original voice information and watermark information after a three-treatment, after wavelet decomposition, the watermark information embedded in the low-frequency signals of the original speech signal realize some hidden part of high-frequency signals. source code is given not only to hide the process, and given in random noise, resampling, compression of information in case of anti-attack features. source code has a clear Notes

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.

Description: The few-color images are often synthetic graphics without complicated color and texture variation, which makes the embedding of invisible digital watermark difficult. This paper proposes a data hiding method that can hide a moderate amount of data in a few-color image, such as cartoon images, binary images, without introducing noticeable artifacts.

Description: 通过在原始数据中嵌入秘密信息--水印来证实数据的所有权 。这种被嵌入的水印可以是一段文字、标识、序列号等 ，而且这种水印通常是不可见或不可察的 ，它与原始数据紧密结合并隐藏其中，并可以经历一些不破坏源数据使用价值或商用价值的操作而能保存下来 。-By secret information- the watermark is embedded in the original data to verify the ownership of the data. This embedded watermark can be a piece of text, logos, serial number, and the watermark is usually not visible or can not detect, which is closely integrated with the original data and hide, and you can experience some of the source data does not destroy the value in use or the operation of the commercial value can be preserved.

压缩包里的其他小算法是为这个提供服务的，不仔细介绍。另外还有一些测试时用到的攻击算法，用来检测性能的。
在运行程序的时候，需要在matlab上自行输入一些代码，才可运行-Scrambling Algorithm Based on Multiple Watermark hide - single watermark embedding algorithm tiqu - single watermark extraction algorithm duohide - multiple watermarking algorithm duotiqu - multiple watermark extraction algorithm compression algorithms other small bag is for the provision of services, not carefully described.

Description: The term digital watermarking was first appeared in 1993, when Tirkel presented two watermarking techniques to hide the watermark data in the images. The success of the Internet, cost-effective and popular digital recording and storage devices, and the promise of higher bandwidth and quality of service for both wired and wireless networks have made it possible to create, replicate, transmit, and distribute digital content in an effortless way.
