Deepfake

Deepfake, a portmanteau of "deep learning" and "fake", is an artificial intelligence-based human image synthesis technique. It is used to combine and superimpose existing images and videos onto source images or videos.

Deepfakes may be used to create fake celebrity pornographic videos or revenge porn. Deepfake pornography surfaced on the Internet in 2017, particularly on Reddit, and has been banned by sites including Reddit, Twitter, and Pornhub. Deepfakes can be used to create fake news and malicious hoaxes.

Non-pornographic deepfakes can be easily found on popular online video streaming sites such as Youtube or Vimeo. A popular program is FakeApp, which makes use of TensorFlow.

Techniques to faking facial gestures and rendering onto the target video as look-alike of the target person were presented in 2016 and allow near real-time counterfeiting of facial expressions in existing 2D video.
