Fake video's are getting real with this (AI) deepfake technology.

Deepfake is a new technology that utilises artificial intelligence to combine and superimpose existing images/video's into a source image or video. You can potentially use this technology to make all kind of fake video's and images that look real. Deepfake pornography is one of the most popular applications at this moment. (Doesn't surprise me :p) Where they put celebrity faces onto a porn actors body. It could also be used to make fake video's of politicians or world leaders, which makes it a potential weapon for political warfare. 

Deepfake video's still don't look 100% real at this moment but the technology is evolving very fast... In 5 years this might become an issue.
