What is a Deepfake?
Deepfake technology originally emerged as a means to exchange and manipulate images and videos using deep learning. Over time, the definition has expanded, and it now commonly refers to the creation of fake videos. Specifically, deep learning algorithms are employed to replace a person’s face, expressions, and voice in a video with that of another individual, enabling them to perform actions or say things they never actually did.
While image editing software like Photoshop has long allowed face-swapping in static images, recent advancements in AI have extended this capability to videos. An example of a deepfake video is the one posted on TikTok in February 2021, featuring @deeptomcruise. Many viewers initially believed the person in the video was Tom Cruise, but it was actually a deepfake with actor Miles Fisher’s face replaced by Tom Cruise’s.
Deepfake Exploit Problem:
The misuse of deepfakes has become a pressing concern. One potential issue is the impersonation of politicians. For instance, a video surfaced in which former US President Barack Obama appeared to deliver a speech flawlessly, but it was actually actor Jordan Peele imitating Obama’s voice while his lip movements were perfectly synchronized with Peele’s words. Such deepfake videos can have far-reaching consequences, including influencing public opinion and causing social unrest.
One notable incident involved a deepfake video of Ukrainian President Volodymyr Zelensky, which falsely depicted him surrendering to Russia. While Zelensky promptly denied the video’s authenticity and it was removed from social media platforms, the prevalence of deepfakes suggests that similar incidents may continue to occur.
Another alarming abuse of deepfakes involves fake pornography, where the faces of individuals in explicit videos are replaced with those of others without their consent. In 2019, a survey revealed that around 96% of the over 14,000 deepfake videos posted online were non-consensual pornographic content. This not only raises legal issues but also violates individuals’ privacy and can lead to serious repercussions for those involved in their creation and distribution.
Applications for Creating Deepfake Videos:
Various applications are available for creating deepfake videos, some of which can be easily accessed on smartphones or computers. Let’s explore a few examples:
1. Xpression (iOS):
Xpression is a smartphone application available for iOS that allows users to manipulate images and make them appear to speak. By utilizing facial movement analysis through the device’s camera, it enables real-time facial expression replacement in videos and images. This application offers creative possibilities, such as making paintings or sculptures come alive or participating in online meetings while appearing professionally dressed, even if you’re in your pajamas in reality.
2. Reface (iOS, Android):
Reface is another popular application that enables users to replace faces in videos or images with their own self-portraits. Whether it’s replacing faces in paintings, animal images, or even iconic movie scenes, this app provides a fun and entertaining way to create deepfake content.
3. Deepfakes Web (PC):
Deepfakes Web is a web-based service used on personal computers. By uploading the original video and a replacement face video, users can create blended videos. This service utilizes videos as replacement material and continuously improves over time to produce more accurate deepfake videos. It should be noted that Deepfakes Web is a paid system.
A Step-by-Step Guide to Making Deepfakes:
Creating deepfake videos involves the utilization of GAN (Generative Adversarial Networks), a deep learning method. GANs employ a generator and a discriminator network to compete with each other, ultimately producing highly realistic images and videos. The process can be summarized as follows:
1. The generator creates a deepfake video, while the discriminator analyzes it to identify any discrepancies.
2. Based on the discriminator’s feedback, the generator refines the video, aiming to make it indistinguishable from genuine footage.
3. This iterative process continues until the deepfake video achieves a high level of authenticity.
GAN has evolved into advanced forms such as DCGAN (Deep Convolutional GAN) and StyleGAN, enabling more stable and realistic image generation.
Positive Potential Uses of Deepfakes:
While the potential for misuse exists, deepfake technology also presents positive opportunities in various domains:
1. Realistic Dubbing of Movies:
Deepfake technology allows for realistic dubbing of movies into multiple languages. Unlike conventional dubbing, which involved replacing only the audio while preserving the original video, deepfakes can generate videos that appear as if the actors were speaking in different languages. This opens up new possibilities for seamless localization of movies for diverse audiences.
2. AI Caster for TV News:
Experiments are underway to explore the use of AI as TV newscasters. This innovation has the potential to revolutionize the television industry, enabling live broadcasts without human presenters, even during late-night programs.
3. Virtual Talents:
AI-generated virtual talents are becoming increasingly prevalent. Collaborations between virtual humans and real-life celebrities are emerging, blurring the boundaries between reality and virtuality in entertainment and advertising.
4. Education:
Deepfake technology can be harnessed in education, particularly in history lessons. By recreating historical figures through videos, students can engage in interactive conversations with virtual personas, providing a unique and immersive learning experience.
Summary:
Deepfakes, powered by deep learning technology, enable the replacement of faces, expressions, and voices in videos. While there are valid concerns about their potential misuse, including political impersonation and fake pornography, deepfakes also offer positive applications. These range from realistic multilingual dubbing in movies to AI casters for news broadcasts and the emergence of virtual talents. As deepfake technology continues to advance, it is crucial for individuals to navigate this landscape responsibly, utilizing its potential while preventing abuse.
Conclusion:
Deepfake videos have revolutionized the realm of AI-generated content, offering both exciting possibilities and serious concerns. While their potential applications range from movie dubbing to virtual talents, the risk of political manipulation and non-consensual pornography demands responsible use and regulation. By understanding the intricacies of deepfakes, individuals can navigate this complex landscape and ensure ethical practices prevail.
