摘要

本文开发了一种用于Facebook社交网络图像保护的隐写方法。该方法隐藏其他信息，如徽标或序列号。将图片上传到社交网络会导致原始图片的图像退化。基于对这种攻击的分析，我们开发了一种基于离散余弦变换- DCT的方法，通过修改余弦域中的系数来隐藏附加信息。对该方法进行了测试，结果表明，该方法对不同攻击的误码率均在1%以下。

In this paper we developed a steganographic method for image protection on Facebook social network. The method hides additional information such as a logo or serial number. Uploading the images on the social network has induced image degradation on the original images. Based on the analysis of this attack we developed a method based on the discrete cosine transform - DCT where additional information is hidden by modifying the coefficients in the cosine domain. The method was evaluated and it is shown that bit error rate (BER) for different attacks was below 1%.
