Deepfakes are a form of altered media. The term "deepfake" is a combination of "deep learning" and "fake." These AI-generated manipulations can involve altering or superimposing content onto existing images, videos, or audio recordings, creating realistic but entirely fabricated scenes.

The most common application of deepfakes involves the manipulation of videos. Using deep learning algorithms, a model can be trained to analyze and mimic a person's facial expressions, gestures, and speech patterns. This enables the creation of highly convincing videos that appear to feature individuals saying or doing things they never did.

Deepfake technology has entertainment potential, such as in the film industry for special effects but it has raised concerns due to its potential misuse. Deepfakes can be used to create misleading content, misinformation, or even to impersonate individuals, leading to ethical and security implications.
