一种用于图像模糊的密码图像加密技术

A cryptographic image encryption technique for facial-blurring of images

Quist-Aphetsi Kester

摘要:

在公共广播媒体和社交网络上,保护与敏感信息、行动主义、虐待案件和其他人有关的人的照片和视频中的面部是非常重要的。在YouTube、Facebook、Twitter等社交网络上,视频被用模糊技术发布,其中一些视频无法恢复。大多数使用的模糊技术可以很容易地使用现成的软件恢复。那些难以恢复的也很容易被滥用者和其他错误的人利用。本文提出了一种图像加密技术,这将使得有可能对选定的面部区域进行加密的基础上RGB像素洗牌的m*n大小的图像。这将使现成的软件难以恢复加密的图像,也使执法机构在图片或视频与虐待案件有关的情况下很容易重建面部。加密方法的实现将使用MATLAB完成。在和时,在加密和解密过程中,图像的总大小不会发生变化。

英文摘要:

Protection of faces in pictures and videos of people in connection with sensitive information, activism, abused cases and others on public broadcasting media and social net- works is very important. On social networks like YouTube,facebook, Twitter and others, videos are being posted with blurring techniques of which some of them cannot be recoverable. Most blurring techniques used can easily be recoverable using off-the-shelf software. The ones that are difficult to be recovered also can easily be used by abusers and ther wrong doers. This paper proposes an image encryption technique that will make it possible for selected facial area to be encrypted based on RGB pixel shuffling of an m*n size image. This will make it difficult for off-the-shelf software to restore the ncrypted image and also make it easy for the law enforcement agencies to reconstruct the face back in case the picture or video is related to an abuse case. The implementation of the encryption method will be done using MATLAB. At the and, there will be no change in the total size of the image during encryption and decryption process.
