基于小波变换的信息隐藏算法研究

随着网络技术和多媒体技术的飞速发展，数字水印技术作为版权保护和信息安全的重要手段得到了广泛的研究和应用，通过在原始数据中嵌入秘密信息水印来证实该数据的所有权或完整性，达到版权保护和信息安全的目的。根据空间域和小波域的特点，提出了一种基于图像分割和小波变换的信息隐藏算法。对提出的算法进行了仿真实验，并对嵌入信息的图像进行各种攻击测试。实验表明，该算法对嵌入信息具有不可见性和良好的鲁棒性。

Algorithm Research of Information Hiding Based on Wavelet Transformation

Watermark technology is widely researched as an important method to safeguard copyright and information.It embeds secret information(that is watermark)into original data to confirm its copyright and integrality.According to the characteristic of spatial domain and wavelet domain,the algorithm of information hiding based on picture division and wavelet transformation information hiding algorithm were proposed.According to the algorithm the simulation experiment is carried out,and the picture embedded information undergoes various attacking testing.
