What are deepfakes and how do they work?
After 2019, there has been a surge in AI usage, with people using AI for productivity and business purposes. A similar trend is seen with deepfakes, as the number of deepfake users continues to grow, along with companies and startups like Modelslab in the field.
Many creators have gained millions of subscribers on social media, showcasing their creativity using deepfake technology, as well as text-to-image, text-to-video, text-to-music, and voice cloning tools.
However, many people are still unaware of this amazing technology. Whether you are a creator, a company, or someone who simply wants to learn more about deepfakes and the technology behind them, this blog is for you.
What is Deepfake?
Deepfake is a type of artificial intelligence technology used to create highly convincing but fake images, audio, and videos. The term "deepfake" is a combination of "deep learning" (a branch of machine learning) and "fake."
Deepfake technology primarily involves manipulating existing images, audio, or video to create realistic but false representations. Deepfakes often involve swapping faces in videos or making someone appear to say or do something they never actually did.
Additionally, deepfakes can generate completely original media that falsely represent people performing actions or making statements they never made. The end result is fake content that appears very real, which can be used to entertain audiences.
How does Deepfake work?
Deepfakes use two main algorithms, a generator, and a discriminator, to create and improve fake content. The generator starts by making the initial fake content based on the desired output, while the discriminator evaluates how real or fake that content looks. This process is repeated many times, with the generator improving its fakes and the discriminator getting better at spotting flaws, which the generator then fixes.
These two algorithms form a system called a generative adversarial network (GAN). GANs use deep learning to understand patterns in real images and then apply those patterns to create fake images. When taking a deepfake photo, a GAN looks at pictures of the person from different angles to capture all the details. For deepfake videos, the GAN also analyzes the person's movements and speech patterns. The discriminator checks and refines the content multiple times to make it as realistic as possible.
There are two main methods to create deepfake videos:
Source video deepfakes: Here, a neural network-based autoencoder studies a video of the person to learn their facial expressions and body language. It then applies these traits to another video, making it look like the person is doing or saying something they didn't actually do.
Face swaps: This involves replacing one person's face with another's in a video, making it appear as though the person in the video is someone else.
Other specific deepfake techniques include:
Audio deepfakes: A GAN copies a person's voice, creating a model of their vocal patterns to make the voice say anything the creator wants. This is often used in video games.
Lip syncing: This technique matches a voice recording to a video, making it seem like the person in the video is speaking the recorded words. If the audio is also a deepfake, it adds another layer of deception. This method is supported by recurrent neural networks.
In summary, deepfakes involve advanced AI techniques to create highly realistic but fake media, using various methods to manipulate images, audio, and video.
Technology requires the development of deepfakes
Developing deepfakes involves a combination of advanced technologies that make creating highly realistic fake media easier, more accurate, and more widespread. The key technologies required include:
GAN Neural Networks: Generative Adversarial Networks (GANs) are crucial for all deepfake content. They use two algorithms: a generator to create fake content and a discriminator to evaluate its realism, iteratively improving the results.
Convolutional Neural Networks (CNNs): These networks analyze patterns in visual data, making them essential for tasks like facial recognition and movement tracking in deepfakes.
Autoencoders: Autoencoders are neural networks that identify important features of a target, such as facial expressions and body movements, and then apply these features to the source video.
Natural Language Processing (NLP): NLP algorithms are used to create deepfake audio by analyzing a person's speech patterns and generating new audio that mimics their voice.
High-Performance Computing (HPC): HPC provides the substantial computing power needed to process and generate deepfake content quickly and efficiently.
Now let's move towards the use of deepfake.
How are deepfakes commonly used?
The use of deepfakes varies significantly. Here are some of the uses of deepfake:
Art and Creativity: Deepfakes can be used to generate new music, artworks, or creative content based on an artist's existing body of work. This can lead to innovative and unique artistic expressions.
Entertainment: Hollywood movies and video games often use deepfakes to clone and manipulate actors' voices and faces for certain scenes. This can be useful for difficult-to-shoot scenes, post-production work, or when an actor is unavailable. Deepfakes are also popular in satire and parody, creating humorous content that the audience knows is not real.
Caller Response Services: Deepfakes can provide personalized responses in automated caller services, making interactions more natural and efficient.
Customer Phone Support: Using synthesized voices, deepfake technology can be used for simple customer service tasks, such as checking account balances or filing complaints.
Historical Reconstructions: Deepfakes can recreate historical figures, allowing them to "speak" in documentaries or educational videos, providing a more engaging learning experience.

How dangerous can be deepfakes?
Based on the purpose of creating deepfakes, they can be harmful in several circumstances, such as:
Blackmail and Reputation Harm: Deepfakes can be used to place individuals in compromising or illegal situations, such as lying, engaging in explicit acts, or taking drugs. These fake videos can be used for blackmail, revenge, or to ruin someone's reputation. Non Consensual deep fake porn, also known as revenge porn, is a common malicious use.
False Evidence: Fabricating false images or audio to create fake evidence that can imply guilt or innocence in legal cases, potentially leading to wrongful convictions or acquittals.
Fraud: Deepfakes can impersonate individuals to obtain personal information, such as bank accounts or credit card numbers. This can also include impersonating executives or employees to access sensitive company information, posing a significant cybersecurity threat.
Misinformation and Political Manipulation: Deepfake videos of politicians or public figures can sway public opinion and spread misinformation. For example, a deepfake of Ukrainian President Volodomyr Zelenskyy was used to create confusion during warfare.
Stock Manipulation: Fake videos or audio can be used to manipulate stock prices. For instance, a deepfake of a CEO making damaging statements about their company could lower its stock price, while a fake video of a technological breakthrough could raise it.
Blackmail and Reputation Harm: Deepfakes can be used to place individuals in compromising or illegal situations, such as lying, engaging in explicit acts, or taking drugs. These fake videos can be used for blackmail, revenge, or to ruin someone's reputation. Nonconsensual deepfake porn, also known as revenge porn, is a common malicious use.
