摘要
近年来随着多媒体技术和网络技术的广泛应用,数字水印越来越重要,在此首先分析了数字水印的意义,接着阐述了m序列产生的原因,以及利用Matlab产生的m序列。由于m序列的随机性,保证了数据的安全性,最后给出了Matlab仿真实验。
In recent years, with the extensive application of multi-media technology and network technology, the digital watermarking becomes more and more important. The paper firstly analyzes the significance of digital watermark, and then elaborates on the causes of sequence m. The m that generated by the use of Matlab sequence, for the random of sequence m, ensures the security of data. Finally it gives the experiment of Matlab simulation.
