摘要:

在调查犯罪活动时,如果有证据,目前的问题是确定录像的可信度,并确定录像是真实的。如今,验证录像的一种方法是识别用于捕获有问题的图像或视频的相机。虽然一种非常常见的方法是使用图像元数据,但这些数据可以通过更改视频内容甚至将来自两个不同摄像机的内容拼接在一起来轻松伪造。鉴于对这一问题提出了许多解决办法,它尚未得到充分解决。我们项目的目的是建立一个算法,该算法使用图像中固有的信息痕迹来识别哪台相机用于捕获图像,使用过滤器,然后在这些过滤器上使用深度神经网络。解决这个问题将对刑事和民事审判甚至新闻报道中使用的证据的核实产生重大影响。

英文摘要:

During the investigation of criminal activity when evidence is available, the issue at hand is determining the credibility of the video and ascertaining that the video is real. Today, one way to authenticate the footage is to identify the camera that was used to capture the image or video in question. While a very common way to do this is by using image meta-data, this data can easily be falsified by changing the video content or even splicing together content from two different cameras. Given the multitude of solutions proposed to this problem, it is yet to be sufficiently solved. The aim of our project is to build an algorithm that identifies which camera was used to capture an image using traces of information left intrinsically in the image, using filters, followed by a deep neural network on these filters. Solving this problem would have a big impact on the verification of evidence used in criminal and civil trials and even news reporting.
