These days we can see tons of images and videos of celebrities, such as A video in which Tom Cruise is talking about Politics and Trump is talking about Hollywood movies. Before diving into how this is possible, let's talk about What is Deepfake and How do deepfakes work? Deepfake is a portmanteau of "deep learning" and "fake". It means using artificial intelligence (AI) techniques to make fake audio, video, or image content that looks and sounds real. Machine learning algorithms are used to make these very realistic fakes.

Artificial intelligence and machine learning can do wonders, from making art to automating admin jobs. But they're also a risk as they can empower bad actors with tricks like deepfake. As this particular technology evolves, it's a good idea to learn how deepfakes actually work and who would even want to use them--both legitimately and illegally. Mainstream applications of deepfake technology mainly revolve around funny, pornographic, or cinematic materials, but a study proved that deepfakes can fool facial recognition. This alone is a reason to worry and put your guard up.
