The mobile camera applications for our phones and computers have become increasingly advanced. We can edit our photos and videos in less than one minute and get millions of views on the World Wide Web. One of the manipulations we can do to our recorded videos is called DeepFake. So, what is it? Image from theconversation Well, DeepFake can be designated as applying Deep Learning techniques to the video to mix two or more videos. Why use it? With DeepFake we can put a person telling something that she or he never told to anyone in is life. No, it is not a polygraph to say the truth. We simply record a video having some speech. Then, using DeepFake we "mix" our face with one from another person, and the final spectator will see the person you chose telling our speech. Imagine recording a video talking about how good you are in Artificial Intelligence and using a celebrity face to say it. In this link , you can see a youtube video showing some examples of DeepFaking. Dee
