About Klayth project WhereCamFrom
The video content of CCTV cameras is very often used as the main evidence for the study of criminal and accidents. However, video content only makes sense when it is original. In addition, recently, Deep Fake videos can generate fake news and cause a lot of social confusion.
When a user uploads a video file to the server, the service gives an integrity check result: for example, "This video file is original and made on iPhone 6" or "This video file was edited by Sony Vegas".
