These sorts of incidents triggered numerous campaigns to outlaw – or at least increase awareness of – deepfake technology. Viral deepfaked videos of political leaders like US House Speaker Nancy Pelosi and Russian President Vladimir Putin have shown the potential dangers of convincing, fake videos. However, more nefarious deepfakes have gained popularity in recent years. The majority of viral deepfakes are mostly harmless videos doing things like morphing Bill Hader into Tom Cruise. The most common deepfakes these days are videos where a famous movie has the lead actor replaced by someone else. In its infancy, public use of deepfake technology was exclusive to a now-banned Reddit thread, but it quickly became another way to make videos for the internet. In summation: a robot makes an image of a person's facial expressions, another one tells it if the expressions look fake, and they argue until all the images are nearly perfect. It will reject inaccurate images, causing more attempts to be generated, and the cycle continues indefinitely, inching toward a 'perfect' recreation of the person. The GAN is a system through which the images from the autoencoder are compared to real images of the targeted person. It processes how that face would blink, smile, grin, and so on. In extremely simple terms, the autoencoder is a computer's way of seeing a face and deciding all the ways it can 'animate'. There's usually an autoencoder and a generative adversarial network (GAN). The process of creating a deepfake has changed as various apps and free software make their way into the public space, but the underlying concept of the more elaborate deepfake videos follow the same principles.

The underlying technology and machine learning processes rose to popularity in the early '90s, evolving from a field of academic research. The term itself, a combination of the words 'deep learning' and 'fake', originated on Reddit in 2017. What used to be limited to only the most well-funded computer scientists and movie studios is now a tool in the hands of comedy outlets and state-run media.īy definition, deepfakes are videos in which a person's face and/or voice are replaced with someone else's by an AI.

Advancements in motion capturing and facial recognition over the past decade have been staggering – and terrifying. As coverage of deepfake technology becomes more prevalent, it's reasonable to wonder how these videos even work.
