What is a Deepfake?
Deepfake is a term that has gained significant attention in the realm of content moderation due to its potential for misuse and the challenges it presents in maintaining trust and safety online.
The term “Deepfake” is a portmanteau of “deep learning” and “fake.” It refers to using artificial intelligence technologies to create or alter digital content, such as deepfake videos, images, or audio – in a way intended to deceive or mislead.
Deepfakes leverage advanced machine learning algorithms to manipulate or fabricate compelling media content that is difficult to distinguish from authentic content.
The technology has been used for a variety of purposes, ranging from harmless entertainment and satire to malicious activities such as disinformation campaigns, identity theft, and deepfake pornography.
Origins of Deepfake Technology
Deepfakes originated in machine learning, specifically deep learning, a subset of artificial intelligence. Deep learning algorithms are designed to mimic the human brain’s ability to learn from experience, allowing them to improve their performance over time as they are exposed to more data.
The first known deepfake was created by a Reddit user in 2017, who used machine learning algorithms to swap the faces of celebrities onto the bodies of pornographic film actors.
Since then, the technology has rapidly evolved and become more sophisticated, increasing the quality and quantity of deepfakes.
Deep Learning and Generative Adversarial Networks (GANs)
At the heart of deepfake technology are deep learning algorithms known as Generative Adversarial Networks (GANs). GANs consist of two parts: a generator, which creates new data instances, and a discriminator, which evaluates the authenticity of the generated data.
The two parts work together, with the generator trying to create data that the discriminator cannot distinguish from actual data and the discriminator trying to determine accurate data from fake data better.
This adversarial process leads to the generation of highly realistic fake content. Over time, as the generator and discriminator learn from each other, the quality of the generated content improves, making it increasingly challenging to distinguish deepfakes from authentic content.
