提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法-We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual fe

MATLAB实现的空域LSB算法，可输入密钥加密文本信息，有较好的交互界面(MATLAB implementation of the airspace LSB algorithm, you can enter key encryption, text information, there is a better interactive interface)

MATLAB实现的LSBM（LSB Matching）算法，可输入密钥加密和解密文本，有较好的交互界面(The LSB matching algorithm,coding by MATLAB. You can encrypt or decrypt the text by input an key. And it has a easy operating interactive interface.)
