基于MATLAB仿真的LSB数字水印技术应用探析

Application of LSB digital watermarking technology based on MATLAB simulation

数字水印技术是一种标志信息所有权的手段,将特定的图形,数字等隐藏在图片中,以保护知识产权,以免大量模仿,盗版带来巨大的经济损失。因此研究数字水印技术十分必要,有利于保护知识产权和促进创新。文中结合实际经验,分析了数字水印技术的特征,对于LSB技术进行了详细分析,并给出使用方法,最终运用MATLAB软件仿真模拟和实例分析。

Digital watermarking technology is a means of ownership of mark information, specific graphics, digital and other hidden in the picture, to protect intellectual property rights, in order to avoid a lot of imitation piracy bring huge economic losses.Therefore, it is necessary to study the digital watermarking technology, which is conducive to protecting intellectual property rights and promoting innovation. In this paper, combined with practical experience, the analysis of the characteristics of the digital watermarking technology, LSB technique for the detailed analysis, and gives the use of methods, end the use of MATLAB software simulation and analysis of an example.
