Deepfake: What It Is, How It's Created, and Why You Should Be Cautious

December 20, 2023

Imagine being able to see a video of your favorite actor saying something they never said, or a politician admitting to a crime they never committed. Fascinating and terrifying at the same time, right? Welcome to the intriguing world of deepfakes, a technology that is blurring the lines between reality and fiction. On this digital labyrinth journey, we'll unravel the mystery behind deepfakes: how a mix of artificial intelligence and digital creativity is creating a new era of audiovisual content.

Deepfakes, deriving their name from the combination of deep learning and fake, are more than mere audiovisual manipulations; they are a testament to the exponential advancement of technology and a reminder of the fragility of our perception.

Throughout this post, you'll not only discover how these impressive digital works are created, but also why it's essential to develop a critical mindset and an interrogative attitude in this digital information era.

What is a deepfake?

Deepfakes are an advanced form of digital manipulation using artificial intelligence and machine learning to create or alter audiovisual content. At their core, a deepfake can make it seem as if someone has said or done something that never actually happened, producing videos or audios that are incredibly difficult to distinguish from the real ones.

This technology, though it may seem like something out of a science fiction movie, is surprisingly accessible and has gained popularity in recent years. Deepfakes have been used in a variety of contexts, from meme creation to manipulation in political environments, to advertising, like the award-winning Cruzcampo (Spanish beer) commercial with Lola Flores, underscoring the need for critical analysis and a detailed understanding of their nature.

The origin of deepfakes

The term deepfake originated around 2017, when an internet forum user with the alias deepfake began posting manipulated videos using artificial intelligence software. These early deepfakes often superimposed celebrity faces onto other people's bodies in videos, quickly generating a mix of awe and concern over their ethical and legal implications.

Since then, the technology has evolved rapidly. What began as a novelty in online forums has transformed into a tool with the potential to create significant changes in the way we consume and trust audiovisual content.

Deepfakes and artificial intelligence

Creating a deepfake is a complex process that relies on the use of artificial intelligence algorithms, specifically those focused on deep learning. These algorithms analyze thousands of images and videos to learn how to mimic a person's facial expressions, movements, and voice. This information is then used to synthesize new images or video sequences that appear real but are completely fabricated.

This ability of AI to replicate and alter reality raises significant questions about authenticity and trust in digital media. While deepfakes can have creative and entertaining applications, they also represent a serious challenge in terms of security, privacy, and ethics in the digital age.

How are deepfakes created?

Creating a deepfake is a fascinating process that combines advanced technology and creative skills. At first glance, it might seem like digital magic, but behind each deepfake is a detailed set of technical steps and artistic decisions.

Deepfake creation process

The process begins with the collection of a large amount of data, specifically images and videos of the person to be replicated. The more material collected, the more realistic and convincing the final result will be. This data is fed into an artificial intelligence system, which uses deep learning techniques to analyze and understand the person's facial features, movements, and expressions.

Then, a second dataset is used, which usually consists of the material in which the person's image or voice is to be inserted. The AI system, through complex algorithms, merges these two datasets, creating a representation that looks natural and realistic.

This fusion is not a straightforward process and requires meticulous adjustments. The synchronization of lip movements, facial expressions, and lighting are essential for the deepfake to be convincing. Additionally, it's necessary to adjust the audio, especially if creating a video where the person appears to be speaking.

Technology behind deepfakes

The key technology behind deepfakes is deep learning, a branch of artificial intelligence. Specifically, convolutional neural networks (CNN) and generative adversarial networks (GAN) are used to process and generate the images and videos.

CNNs are effective in recognizing and replicating patterns in images, such as facial features. GANs, on the other hand, are a set of two neural networks that work together: one generates the image, while the other evaluates its authenticity, in a continuous improvement process until achieving a result that is difficult to distinguish from reality.

This sophisticated use of AI not only demonstrates the power of modern technology but also highlights the need for deep understanding and careful regulation, given the potential for misuse of these tools.

The impact of deepfakes on society

Deepfakes are not just a technological feat; their impact extends far beyond the digital realm, affecting fundamental aspects of our society. These digital creations have the potential to influence public opinion, alter the perception of reality, and challenge the authenticity of information.

Deepfakes in politics and media

In the political and media arena, deepfakes represent a powerful tool for disinformation and manipulation. A notable case was the deepfake of Ukrainian President Volodymyr Zelensky, where he supposedly asked Ukrainian forces to surrender to the Russian army. Discussions have also centered on deepfakes related to Russian President Vladimir Putin, highlighting the sophistication and political manipulation potential of this technology.

Identity impersonation with deepfakes

Beyond politics, deepfakes pose a serious risk of identity impersonation. In entertainment, the TikTok account "deeptomcruise" created deepfakes of actor Tom Cruise, deceiving millions. In the business world, a deepfake was used to impersonate the head of communications at Binance, aiming to deceive representatives of other companies in cryptocurrency transactions. These cases demonstrate the threat deepfakes pose in terms of security and privacy.

How to Detect and Protect Yourself from Deepfakes

Knowing how to identify and protect yourself from deepfakes is crucial, especially as the technology advances and becomes even more sophisticated. Here are some key tips for spotting these forgeries:

  • Inconsistencies in audio and video: Pay attention to mismatches in lip movement or facial expressions that do not match the audio.
  • Quality and resolution: Deepfakes often have flaws in image quality or resolution, particularly around the eyes and mouth.
  • Lighting and shadows: Check if the shadows and lighting on the person's face do not align with the environment.
  • Blinking and natural movements: People in deepfakes may not blink naturally or have unusual facial movements.

Prevention against the Threat of Deepfakes

To prevent the impact of deepfakes, it's essential to adopt a critical and questioning stance towards the information we consume:

  • Source verification: Always verify the source of a video, especially if the content is surprising or provocative.
  • Education and awareness: Stay informed about deepfake technologies and teach others to be critical of the content they consume.

Tools for Deepfake Detection

Various tools and software have been developed to help identify deepfakes. Here are some of the most well-known:
