Cryptography and Steganography of Video Information in Modern Communications 摘要

原文:
In this paper image cryptography and steganography performed in frequency domain using random phase mask encoding are presented. The use of random phase mask allows to deccorrelate initial image and makes it unrecognized. This property is used for proposed image encryption and for steganography to increase the security level of the encoded image and to make it less visible. Finally, two keys are needed to decrypt the image. The efficiency of the proposed approach is demonstrated by the computer modeling.

意思是說:
在這篇論文中圖像的密碼學和偽裝學實行在頻率高的領域中利用隨機階段偽裝加密呈現出來。隨機階段偽裝的使用允許沒有關聯的原始圖像讓她變成無法辨識的圖像。這所有權作為被提議的影像密碼技術和偽裝學增加被改為編碼的影像的安全水準而且讓它比較不看得見。最後,解密影像需要二把鑰匙。 提議方法的效率被電腦模型示範出來。
