What Exactly Is Deepfakes AI?

Deepfake technology, often dubbed A.I. that deceives, derives its name from deep learning, a branch of artificial intelligence. Deepfake AI employs deep learning algorithms, which autonomously learn to tackle complex problems using extensive datasets to manipulate faces in videos, images, and other digital content, rendering the fabricated material eerily realistic. Creating deepfake content involves two critical algorithms in a competitive relationship.

One algorithm, known as the generator, generates counterfeit digital content. At the same time, the other, called the discriminator, assesses whether the content is genuine or synthetic. With each iteration, the discriminator provides feedback to the generator, enabling it to refine its techniques for producing more convincing Deepfakes. These two algorithms operate in a generative adversarial network (GAN) system. Through a series of algorithms, the GAN trains itself to identify patterns crucial for mimicking authentic characteristics, enhancing its ability to generate deceptive images and videos.

Usages Of Deepfakes AI


Deepfake technology poses a grave threat in the hands of those seeking to blackmail or tarnish others’ reputations. Despite its widespread use, particularly against the older generation, many are still unaware of technology capable of seamlessly replacing faces in videos. A troubling example of this misuse occurred when Raffaela Spone of Pennsylvania distributed Deepfakes videos depicting members of a cheerleading group engaging in illicit activities to sabotage her daughter’s rivals. Fortunately, the victims’ families alerted the authorities, thwarting Spone’s malicious scheme.


Politicians are frequent targets of deepfake videos, with compromising footage posing a significant risk to their reputations and electoral prospects. In 2019, media artists Francesca Panetta and Halsey Burgund of MIT produced a deepfake video featuring former U.S. president Richard Nixon. The footage depicted Nixon falsely announcing the failure of the Apollo 11 mission, claiming that none of the crew returned from the moon—a speech scenario prepared for potential use. The artists spent six months collaborating with various specialists to create deepfakes so realistic that they aimed to showcase the technology’s potential. Their website offers interactive educational resources to help users discern deepfake content and its implications.


Deepfake technology has found a niche in the art world, where it is used to animate famous portraits and bring them to life. International researchers applied this technique to Leonardo da Vinci’s iconic Mona Lisa, enabling the renowned painting to speak. Similarly, the Dali Museum in Florida utilized archival video footage to recreate Salvador Dali himself, enhancing the museum experience for visitors.


Deepfake technology is often employed in filmmaking to alter or replace actors’ faces. A notable example is seen in “Rogue One: A Star Wars Story,” where deepfake technology was utilized to recreate the likenesses of Princess Leia and Grand Moff Tarkin, preserving the continuity of the beloved franchise.


Disney Research Studios is pioneering its own deepfake visual effects technology, aiming to streamline the process of obtaining desired individuals for film projects. While this technology offers time and cost-saving benefits, its current limitation lies in producing high-quality results only in lower resolutions, requiring additional effort to achieve satisfactory outcomes. This technology mirrors the approach taken in the previously mentioned Star Wars movie.


Social media platforms have varied responses to deepfake content. While some, like Facebook and Twitter, actively combat Deepfakes by updating their policies and banning synthetic media, others embrace the technology. Snapchat introduced face-swapping camera features in 2016, while TikTok allows users to seamlessly swap faces in videos, demonstrating the diverse applications of deepfake technology in social media.


Deepfake technology extends beyond impersonating real individuals to creating entirely fictional characters. One example is Oliver Taylor, a fabricated persona created by unknown individuals. Taylor’s false social media profiles portrayed him as a Jewish student actively involved in anti-Semitic activities, attracting attention from London academic Mazen Masri. This example highlights the potential for deepfake technology to be used maliciously. In 2017, researchers and entrepreneurs established Synthesia, an AI-powered software capable of generating audiovisual content for synthetic media, enabling clients to create realistic videos featuring fictional characters.

Approaches Employed To Create Deepfakes AI

Source Video Deepfakes

This technique uses a deepfake autoencoder based on neural networks to learn essential aspects of the target, like body language and facial expressions, by analyzing attributes from a source video. The autoencoder comprises an encoder, which identifies relevant attributes, and a decoder, which applies these attributes to the original video, seamlessly integrating them.

Audio Deepfakes

In audio Deepfakes, a Generative Adversarial Network (GAN) replicates a person’s voice, constructing a model based on their vocal patterns. This model can then be manipulated to make the voice say anything the creator desires. This technique, often employed by video game developers, enables creating realistic-sounding audio content.

Lip Syncing

Lip syncing is another prevalent technique in the realm of Deepfakes, involving the synchronization of a voice recording with video footage. This process aligns the movements of the person’s lips in the video with the words spoken in the audio recording, creating the illusion that the individual is speaking the recorded words. This technique adds a layer of deceit if the audio is altered. Lip syncing is facilitated by recurrent neural networks, enhancing the accuracy and realism of the final output.

How Cybercriminals Use Deepfakes?

Impersonating high-profile individuals

Cybercriminals can create believable audio or video recordings of prominent people doing or saying things they never did using Deepfakes. These manipulated media can spread misinformation, tarnish reputations, or facilitate financial fraud.

Stealing personal information

Deepfakes facilitate the creation of realistic fake I.D.s or passports, which attackers use to perpetrate identity theft or fraud, enabling them to steal money or access sensitive information.

Infiltrating organizations

Cybercriminals leverage Deepfakes to produce videos or audio recordings simulating interactions with personnel from legitimate organizations. These fabricated communications may be used to gain unauthorized access to sensitive data or coerce individuals into making payments.

Despite being in its early stages, deepfake technology continues to advance rapidly. To reduce the risks associated with Deepfakes, it is imperative to have a vigilant and critical attitude toward information obtained from the internet.
