LSB替换隐写
说明： LSB(英文 least significant bit)即最低有效位。LSB加密是信息隐藏中最基本的方法。由于人们识别声音或图片的能力有限，因此我们稍微改动信息的某一位是不会影响我们识别声音或图片的。(LSB replace steganography)

SVD-based-watermarking
基于SVD的DCT域和DWT域的经典水印算法，该算法通过提取水印水印的主成分并把该主成分嵌入到奇异值矩阵，鲁邦性非常高。(the principal components of the watermark are embedded into the host image in discrete cosine transform (DCT) and for the second method, those are embedded into the host image in discrete wavelets transform (DWT). To improve the robustness, the particle swarm optimization (PSO) is used for finding the suitable scaling factors.
