论文摘要
我们激励并发展了新的数字取证线。同时，我们提出了一种新颖的摄影师识别方法，这是一个很少探索的作者归因问题。我们报告了一项概念验证研究，该研究显示了我们方法的可行性。我们的贡献包括一种新的法医方法，用于摄影师去匿名化，并揭示了以前被忽略的新型隐私威胁。我们创作的成功建立在我们发现的新光学侧渠道之上，以及如何有效利用它。我们还进行了首次尝试桥接侧通道和反问题，这两个字段似乎完全彼此隔离，但具有深厚的连接。
We motivate and develop a new line of digital forensics. In the meanwhile, we propose a novel approach to photographer identification, a rarely explored authorship attribution problem. We report a proof-of-concept study, which shows the feasibility of our method. Our contributions include a new forensic method for photographer de-anonymization and revealing a novel privacy threat which had been ignored before. The success of our creation builds on top of a new optical side-channel which we have discovered, as well as on how to exploit it effectively. We also make the first attempt to bridge side channels and inverse problems, two fields that appear to be completely isolated from each other but have deep connections.
