Deep Fake vs. Cheap Fake: Understanding the Differences and Implications
AIINNOVATIONDEEP FAKE
The rise of artificial intelligence has brought significant advancements in synthetic media creation. Among these, "deep fakes" and "cheap fakes" have garnered considerable attention for their ability to manipulate reality. While both terms refer to falsified media, they differ in complexity, technology, and potential impact.
What is a Deep Fake?
Definition: Deep fakes are highly realistic and sophisticated synthetic media generated using deep learning algorithms. These algorithms, often based on Generative Adversarial Networks (GANs), can create or alter video and audio content to make it appear authentic.
Technology: Deep fakes utilize advanced machine learning techniques, particularly GANs, which involve two neural networks: a generator and a discriminator. The generator creates fake media, while the discriminator evaluates its authenticity. Through continuous training, the generator improves its ability to produce realistic content.
Tools Used:
DeepFaceLab: A popular tool for creating deep fake videos.
Faceswap: An open-source software for deep fake creation.
GANs: The fundamental technology behind deep fakes, involving generator and discriminator networks.
Adobe Voco: A prototype tool that can edit voice recordings convincingly.
AI Improvements: AI has significantly enhanced the realism and accessibility of deep fakes. Improved algorithms allow for more accurate facial expressions, voice synthesis, and seamless integration into existing media.
Examples:
Entertainment: Deep fakes have been used to digitally resurrect deceased actors or de-age actors in films.
Misinformation: Deep fakes have the potential to spread misinformation by creating realistic videos of public figures saying or doing things they never did.
Case Study: In 2020, a deep fake video of former President Barack Obama surfaced, in which he appeared to say things he never actually said. The video, created by filmmaker Jordan Peele, was meant to highlight the dangers of deep fake technology and raise awareness about its potential misuse.

What is a Cheap Fake?
Definition: Cheap fakes, also known as shallow fakes, are manipulated media created using simple, low-tech methods. Unlike deep fakes, cheap fakes do not rely on advanced algorithms and are easier to produce.
Technology: Cheap fakes can be created using basic video and audio editing software. Techniques include slowing down, speeding up, or re-editing existing footage, as well as adding or removing audio.
Tools Used:
Adobe Premiere Pro: A widely used video editing software.
Final Cut Pro: Another popular video editing tool.
Audacity: An open-source audio editing tool.
Simple Image Editing Software: Tools like Photoshop for manipulating images.
AI Improvements: While AI's role in cheap fakes is less pronounced than in deep fakes, AI tools can still assist in automating and enhancing basic editing tasks, making the creation process faster and more efficient.
Examples:
Media Manipulation: Cheap fakes are often used to distort the context of a video or audio clip, such as selectively editing a speech to alter its meaning.
Social Media: These types of fakes frequently appear on social media platforms, where they can quickly spread and influence public opinion.
Case Study: A notable example of a cheap fake involved a video of U.S. Speaker of the House Nancy Pelosi. The video was slowed down to make it appear as though she was slurring her words, creating the false impression that she was intoxicated. This video spread rapidly on social media, misleading many viewers.
AI Tools for Deep and Cheap Fakes
AI Tools for Deep Fakes:
StyleGAN: Used for creating highly realistic images.
Recurrent Neural Networks (RNNs): Employed for realistic voice synthesis and lip-syncing.
Deep Learning Libraries: TensorFlow and PyTorch for building and training GAN models.
AI Tools for Cheap Fakes:
Image Recognition Algorithms: To automate the selection and editing of images.
Natural Language Processing (NLP): For editing and synthesizing speech in audio clips.
AI-Assisted Editing: Tools that use AI to suggest edits and improvements.
White Fake: A New Category?
Definition: White fakes refer to synthetic media created for benign or positive purposes, such as satire, education, or raising awareness. Unlike deep fakes or cheap fakes, white fakes are not intended to deceive or harm but to inform or entertain.
Example: A recent example involves President Joe Biden. In a satirical video, President Biden was depicted humorously commenting on a pop culture event. The video, clearly marked as satire, used deep fake technology to superimpose Biden's face onto another actor's body, creating a humorous yet obviously fake scenario. This type of white fake aims to entertain while making it clear that the content is not real.
Implications of Deep Fakes and Cheap Fakes
1. Misinformation and Trust: Both deep fakes and cheap fakes can undermine public trust in media. Deep fakes, with their high level of realism, can be particularly damaging, making it difficult for people to discern between real and fake content.
2. Security Threats: Deep fakes pose significant security risks, as they can be used for identity theft, blackmail, and political manipulation. Cheap fakes, while less sophisticated, can still influence public opinion and cause harm.
3. Legal and Ethical Considerations: The rise of synthetic media has prompted discussions about legal and ethical frameworks to address their creation and dissemination. Ensuring that these technologies are used responsibly is crucial to mitigate their negative impact.
4. Detection and Mitigation: Advancements in AI are also being used to develop tools for detecting deep fakes and cheap fakes. Researchers and tech companies are working on algorithms that can identify manipulated media and help prevent the spread of misinformation.
Conclusion
The advent of deep fakes and cheap fakes has introduced new challenges in the realm of digital media. While deep fakes represent a significant technological achievement, their potential for misuse is a cause for concern. Cheap fakes, although less sophisticated, can still be highly effective in spreading misinformation. As technology continues to evolve, it is essential to develop robust detection methods and establish ethical guidelines to ensure that synthetic media is used responsibly. Understanding the differences between deep fakes and cheap fakes is a crucial step in navigating the complexities of the digital age.
