How deepfakes work and their impact

While this innovation has its creative uses, it also raises significant concerns about misinformation, privacy violations, and security risks. This article, based on research conducted by Slotozilla, delves into how deepfakes are created, their potential dangers, and how you can protect yourself from falling victim to digital deception.

What Are Deepfakes?

Deepfakes refer to media—videos, images, or audio—created or manipulated using artificial intelligence (AI) to alter or replace a person’s likeness, voice, or actions. The technology behind deepfakes involves Generative Adversarial Networks (GANs), where one network generates the fake content, and the other evaluates its authenticity. This process has been refined to a point where deepfakes can now be incredibly difficult to distinguish from real content, making them both fascinating and alarming.

According to a 2020 report by Sensity AI, over 14,000 deepfake videos were detected online, with a significant portion being used for malicious purposes, including misinformation and defamation. As deepfake technology continues to advance, its implications for privacy, security, and trust in media become increasingly concerning.

How Deepfakes Work

Deepfakes are created using deep learning, a subset of machine learning that teaches AI to mimic human brain functions. By analyzing large datasets of images, videos, or audio of a person, the AI learns to replicate their facial expressions, voice, and movements. Once the system is trained, it can generate new content that appears disturbingly real, such as swapping faces or mimicking speech.

The process involves several stages: data collection, model training, content generation, and refinement. The more data available for training the model, the more realistic the deepfake becomes.

The Dangers of Deepfakes

Deepfakes present several risks to society, ranging from the spread of misinformation to privacy violations. One of the most significant concerns is their potential use in political manipulation. For instance, in 2018, a deepfake video featuring President Obama, created by filmmaker Jordan Peele, went viral. The video, which depicted Obama delivering insulting remarks about then-President Trump, was created to highlight the dangers of deepfake technology and demonstrate how easily public opinion could be swayed through manipulated media.

Beyond political manipulation, deepfakes also pose a risk for identity theft and financial fraud. There have been reports of hackers using deepfake technology to impersonate CEOs and other high-level executives. In one notable case, fraudsters used a deepfake of a CEO’s voice to issue a command for a large financial transfer, resulting in significant monetary loss.

Expert Insights

A feature by WVUToday highlights growing concerns about deepfake technology and its impact on public trust.

Laurel Cook, associate professor of marketing at WVU John Chambers College of Business and Economics, emphasizes the importance of a critical approach to online content, stating: "When navigating content, particularly online, adopting a perspective that treats deepfakes and other tech-altered information akin to spam — similar to our approach with junk mail or pop-up ads — proves advantageous."

Amy Cyphert, Lecturer in Law at WVU College of Law and director of the WVU ASPIRE Office, warns about the potential dangers of deepfakes, particularly in political contexts: "Deepfakes are very concerning because we tend to trust video and the sound of people’s voices as evidence sufficient to believe what we’re hearing or seeing to be real. That’s just not the case anymore. I’ve been worried about this for years, and I’m really worried about it in terms of election interference."

Global Deepfake Statistics

Slotozilla gathered data to analyze the prevalence of deepfakes worldwide, revealing the following statistics by country:

• United States: 3,000 deepfake videos
• Philippines: 4,500 deepfake videos
• Vietnam: 3,050 deepfake videos
• Japan: 2,800 deepfake videos
• Belgium: 2,980 deepfake videos
• Romania: 1,766 deepfake videos
• Slovakia: 1,500 deepfake videos
• South Africa: 1,200 deepfake videos
• U.A.E.: 1,000 deepfake videos
• Algeria: 1,000 deepfake videos
• Canada: 477 deepfake videos
• Mexico: 700 deepfake videos
• Brazil: 828 deepfake videos
• Argentina: 766 deepfake videos

These numbers reflect the global reach of deepfake technology and highlight the growing problem of fake media that can influence public opinion and damage reputations.

Protecting Yourself from Deepfakes

As deepfake technology continues to evolve, it's essential to stay alert and well-informed. Always verify the source of any video or audio you come across online, especially if it seems unusual or controversial. Pay attention to signs of manipulation, such as unnatural facial expressions or inconsistencies in speech.
