This is a demo platform aimed to facilitate the verification of UGC image and video content posted on YouTube, Twitter and Facebook. In contrast to other approaches, which attempt to analyze the media items themselves for traces of forgery, this platform analyzes the media context: The characteristics of the poster, any relevant user comments, the local weather reports at the time of the event, and other contextual pieces of information are aggregated and presented to the user for analysis. To test the service, simply copy and paste a YouTube, Facebook* or Twitter URL for videos into the box or a Facebook or Twitter URL for images, then click "Verify"
*Right click on the Facebook video and copy the video URL
