AI algorithm detects deepfake videos with high accuracy

Artificial intelligence (AI) contributes significantly to good in the world. From reducing pollution to making roads safer with self-driving cars to enabling better healthcare through medical big-data analysis, AI still has plenty of untapped potential. Unfortunately, just like any technology in the world, AI can be used by those with less noble intentions. Such is the case with a certain AI-based technique called "deepfake" (combination of "deep learning" and "fake"), which uses deep neural networks to easily create fake videos in which the face of one person is superimposed on that of another. These tools are easy to use, even for people with no background in programming or video editing.
