摘要
文章提出将全数字全息术应用于音频信息加密。先将一维音频数据读入并保存为二维图像数据,对此图像数据应用全数字全息术进行信息加/解密,从而最终达到音频信息的加/解密,并给出结果以及结果分析。可以看出,应用基于光学原理的全数字全息术在音频信息加/解密方面取得了比较好的效果。
It is presented here that the all-digital holography is applied tothe digital audioencryption. Thedigital audio signal named ＂way＂ is turned into one dimensional data. Then the one-dimensional data is stored in two-dimensional image data. The all-digital holography is applied to the eneryption/decryption processes of the image, which realize the cneryption/decryption of the digital audio. The results are given in this paper. The application of the alldigital holography on the digital audio eneryption gets the good results.
