THE deepfake is a Artificial Intelligence (AI), which uses machine learning algorithms to create videos or images that appear to be real but are actually fakeThe technique involves using a machine learning algorithm to analyze and learn from a large number of existing images and videos, then create a digital representation of a person's face or body. This model can then be used to create an image or video that appears authentic but is actually a fake.
There are several ways to create a deepfake, but most methods involve the use of an artificial neural network known as a generative adversarial network (GAN). A GAN is composed of two parts: the generator and the discriminator. The generator creates the fake image or video, while the discriminator evaluates whether the image or video is real or fake.
The process of creating a deepfake typically involves training a GAN with images or videos of a real person, so it can learn to accurately replicate their facial features and expressions. Once the GAN has been trained, it can be used to create images or videos that appear authentic but are actually fake.

How are deepfakes being used?
This technique can be used in a variety of ways, whether for positive purposes such as creation of special effects in films, and other times for negative purposes, such as dissemination of fake news.
The technology for generating deepfakes is increasingly advanced, and this also includes the field of computer graphics. Recently, researchers developed software that can map faces, synchronize facial expressions, and even switch identities in a virtually seamless manner. This may seem like science fiction, but it's pure reality! The technology, which uses artificial intelligence to replace people's faces and synchronize facial expressions, makes the final content look as natural as possible.
In the past, it was already possible to do this, but not with such precision. Today, face mapping programs are becoming more and more accurate, which can be dangerousNow, with the advancement of AI techniques, it is possible to make this exchange practically imperceptibly. This is a breakthrough that raises a warning, as malicious people can use this technology for illicit purposes.
A worldwide phenomenon, but a dangerous one.
The program has become a success, its nature is ambiguous and can have different uses and consequences. On the one hand, the Deepfakes have the potential to be used in areas such as entertainment, advertising and cinema, allowing the creation of more engaging and realistic content.. Additionally, they can also have positive uses in fields such as medicine, where they can be used to simulate surgical procedures and train doctors.
On the other hand, deepfakes also can be used maliciously to spread misinformation, defame people, cyber fraud and even to commit crimes such as pedophilia, blackmail and extortion.
Therefore, it is important that measures are implemented to prevent the malicious use of deepfakes, such as creating laws and regulations for the use of this technology, as well as raising public awareness of the risks associated with deepfakes.
