Deepfake

A deepfake is a type of synthetic media that replaces a person's likeness and voice with someone else's using artificial intelligence. Key aspects:

Uses neural networks like GANs and autoencoders to create forgeries.
Can transpose faces, facial expressions, voices into target videos.
Enables creating fake suggestive photography without consent.
Poses threats of political disinformation and fraud.
Becoming more accessible through apps and open source tools.
Hard to detect as AI generation quality improves.

Defense strategies:

Digital watermarking and certification of authentic recordings.
Media forensics to analyze editing patterns.
Using cues like inconsistent backgrounds and lighting.
Limiting distribution and accessibility of source materials.

Deepfakes highlight emerging threats of AI-powered misinformation. Regulation, transparency, and public awareness are critical to mitigate potential harms. More research into detection methods remains imperative.
