Microsoft launches a deepfake detector tool ahead of US election [techcrunch.com]
Microsoft has added to the slowly growing pile of technologies aimed at spotting synthetic media (aka deepfakes) with the launch of a tool for analyzing videos and still photos to generate a manipulation score.
The tool, called Video Authenticator, provides what Microsoft calls "a percentage chance, or confidence score" that the media has been artificially manipulated.
"In the case of a video, it can provide this percentage in real-time on each frame as the video plays," it writes in a blog post [microsoft.com] announcing the tech. "It works by detecting the blending boundary of the deepfake and subtle fading or greyscale elements that might not be detectable by the human eye."
