已经提出了加密然后压缩(ETC)系统来通过不可信的通道提供商安全地传输图像。在这项研究中，ETC系统被应用于Twitter等进行图像处理的社交媒体。评估了ETC系统中使用的基于块置乱的加密方案对社交媒体上图像篡改的稳健性。其目的是调查Facebook、Twitter、Google+、Tumblr和Flickr这五家社交网络服务(SNS)提供商是如何操纵图片的，并确定上传到SNS提供商的加密图片是否可以避免被此类操纵扭曲。在一项实验中，加密和未加密的JPEG图像被上传到不同的SNS提供商。结果表明，ETC系统适用于这五家SNS提供商。
Encryption-then-Compression (EtC) systems have been proposed to securely transmit images through an untrusted channel provider. In this study, EtC systems were applied to social media like Twitter that carry out image manipulations. The block scrambling-based encryption schemes used in EtC systems were evaluated in terms of their robustness against image manipulation on social media. The aim was to investigate how five social networking service (SNS) providers, Facebook, Twitter, Google+, Tumblr and Flickr, manipulate images and to determine whether the encrypted images uploaded to SNS providers can avoid being distorted by such manipulations. In an experiment, encrypted and nonencrypted JPEG images were uploaded to various SNS providers. The results show that EtC systems are applicable to the five SNS providers.
