How DeepFake actually works

 DeepFake is the process where a program swaps faces with anyone in any video. This A.I. Technology is extremely powerful, it goes through millions of frames to swap faces. Every frame is accurate. The outcome video is very realistic and anyone can be easily fooled by it. These programs use not just one, but two different A.I.s working together at the same time. The first A.I. will go through and scan many images of the subject who is to be faked and then create new faked images. The second A.I. will then examine those faked images and compare them to the real images, and if the second A.I. spots a difference between them, the second A.I. will mark the image as an obvious fake and will pass this information to the first A.I. So the first A.I. takes this information and continuously adjusts the fake images based on the second A.I.’s feedback. Then the new faked images are again passed to the second A.I. for comparison, then again, if the second A.I. spots errors it will share that information with the first A.I. and then again the cycle continues till the point that the second A.I. cannot spot the difference. In simple words; the first A.I. creates fake images, then it shares those faked images to the second A.I. And the second A.I. gives feedback to the first A.I. telling it to redo this image as it is an obvious fake, or telling it to move on to the next image as the second A.I. can't spot the difference.

This system is called Generative Adversarial Network and although the idea behind it is fairly simple, with the ongoing growth of hardware and processing power, it has become a very powerful tool for producing convincing looking fakes. DeepFake also features lots of cool applications. An A.I. network like this can analyse lots of people with a similar look to create a fake model for advertising purposes. It’s way cheaper than to hire an actual person as a model and paying them for a photo shoot. DeepFake could also help with age progression photos to help find missing people, or even to upscale old school pixelated video games so they fit in with the modern displays. But this was simply the tip of the ice-berg. Majority of DeepFake videos right now are pornographic in nature, with the idea of being to swap in a celebrity's face without their consent. Resulting in several actresses falling witness to this activity. Something which also raises a bright red flag is DeepFake’s terrifying ability to match even accurately match up lip movements which raises a concern that it might be used to spread fake videos of politicians saying… well… anything that might get them to the unpleasant side of the public opinion. And when it comes to politics, people often tend to blindly believe almost anything they see.
