![]() ![]() Over the past few years, deepfakes of celebrities and politicians have gone viral, with a deepfake of the Queen being used for Channel 4’s alternative Christmas speech.Īway from the comedic videos and celebrity morphing, deepfakes have also been used to transplant the faces of famous women like Scarlett Johansson into porn videos. This copy of a person can then be superimposed onto the body of a stand-in actor – placing a person in situations they’ve never been in and saying things they have never said. ![]() The first network then tries to generate new images to fool the second into thinking they are real. However, currently, the need of the hour is making people aware that such videos exist and how it is crucial for them to not spread such fake videos to maintain peace and harmony in society.Tom Cruise randomly pops up in Stormzy’s new music video and couldn’t look happierĭeepfake technology first emerged in 2017, resulting in highly realistic fake videos created using a kind of artificial intelligence.Ī machine-learning technique called a GAN (generative adversarial network) is used, with a person feeding one network hours of real video and images of a person to give a machine an understanding of what a person looks like from different angles, while another network is trained how to pick out the target person from a database of many different people. And there are several developers who are working on their own version of deepfake detection. Thus this calls for technology that can help find if a video is a deepfake or the real deal. Similarly, several deepfake porn videos have surfaced on popular porn sites with the faces of females swapped with those of popular female actors. While this was a harmless video, imagine the same video saying something provocative or harmful, hurting people’s feelings and causing disharmony online. For many who haven’t seen Tom Cruise that often, they would easily call the deepfake video the real deal. With deepfakes getting more and more realistic with each version, it is also causing a rise in the misuse of this technology. This was so seamlessly done that it felt almost natural, but also very creepy. In the video as soon as Bill Hader would mimic Cruise, his face would gradually transition, looking like him. Just last year, we saw another deepfake on a Bill Hader video where he was mimicking Tom Cruise. Once the training is complete you just need to fuse the encoder trained on the diverse faces with the decoder trained on Amitabh Bachchan’s face, making the actor’s face appear on someone else's seamlessly. Training for both of these faces can be done successfully by using a facial recognition algorithm to video frames to capture different poses and lighting conditions. For instance, if you had to create a deepfake for a celebrity like Amitabh Bachchan, you’d require two encoders - one trained with images of the actor’s face and one trained on images of a wide diversity of faces. VAE is designed in a way to encode images into low-dimensional representations and decode those representations back into images. According to them, the creator replaces one person’s face with another with the help of facial recognition algorithms as well as a deep learning computer network called a variational auto-encoder, often referred to as VAE. MIT Media Lab also shared how one creates a deepfake. ![]() According to MIT Media Lab it is a specific type of synthetic media where a person’s face in an image or video is swapped with another’s.ĭo you remember fun face-filters on Snapchat with one of them allowing you to add someone else’s face itself as a filter? This is the same thing, but on steroids, and with crazy realism. To the uninitiated, a deepfake is essentially a video that has been doctored using artificial intelligence to appear like the real deal. ![]()
