Microsoft launches a deepfake detector tool ahead of US election
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 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."

Two possibilities. One, it doesn't work reliably, in which case it's useless. Two, it works reliably, in which case it will be used to train systems to produce better, undetectable deepfakes.
