Deepfake detection is a field of research and a set of technical methodologies focused on identifying digitally manipulated media, such as videos, audio recordings, and images, generated using artificial intelligence techniques, particularly deep learning. It investigates subtle inconsistencies, artifacts, or anomalies introduced during the synthetic media generation process, employing computational techniques from machine learning, computer vision, and audio analysis to distinguish authentic content from fabricated material. Its significance lies in safeguarding information integrity, combating the spread of disinformation, and mitigating the potential societal harms associated with increasingly realistic synthetic media.
