A deepfake is a photo, video or audio clip that has been generated or altered by machine learning to show a real, identifiable person doing or saying something they did not do. The word appeared in 2017 as a Reddit username; by 2024 a US House hearing cited that 98% of deepfake videos online were pornographic, and 99% targeted women. ## How are deepfakes made? Two model families do most of the work. GANs , introduced in 2014, trained a generator against a discriminator and powered the first face-swap programs such as DeepFaceLab, archived in November 2024. Diffusion models, released as Stable Diffusion in August 2022, now dominate image work because they follow prompts and masks better. Every method invents the missing information; none reveals anything true about the subject. Deepfakes cause unique harms that are disproportionately experienced by women. — Dr. Waldman, witness testimony at the US House hearing “Addressing Real Harm Done by Deepfakes”, March 12, 2024 , accessed September 3, 2026 ## How reliable is deepfake detection? Detectors are classifiers trained on datasets such as FaceForensics++ (2019, 1.8 million manipulated frames). They degrade on new models, compression and re-encoding. Provenance systems such as C2PA Content Credentials take the opposite route: a signed manifest records how a file was made, but the signal disappears in a screenshot. Our deepfake detection entry lists tools and reported error rates. ## Which US laws apply to sexual deepfakes in 2026? ## What should a victim do first? ## What does “Related tools we reviewed” mean for What is a deepfake?? ## What does “Pornworks” mean for What is a deepfake?? ## What does “Wavespeed” mean for What is a deepfake?? ## What does “Face-swap tools compared” mean for What is a deepfake?? ## What does US law say? > “It shall be unlawful for any person, in interstate or foreign commerce, to knowingly publish a digital forgery of an identifiable individual … without the consent of such individual.” > > — TAKE IT DOWN Act, 15 U.S.C. § 6851 note, accessed September 3, 2026, [congress.gov](https://www.congress.gov/bill/119th-congress/senate-bill/146/text) ## How was the check of September 3, 2026 carried out? ## Frequently asked questions **What is What is a deepfake? in one sentence?** Definition and typology, the model families behind fakes, what detection can and cannot do, and the US statutes that apply in 2026. **Does What is a deepfake? apply in the United States?** Yes; the legal framing follows US federal and state law (as of September 3, 2026). **Does clothoff.ai offer a tool for this?** No. The site is an editorial project and processes no images. **Which images may be used?** Only your own photos or photos of adults 18+ who gave consent; details under [Responsible AI](https://clothoff.ai/responsible-ai/). **How often is the entry checked?** Last on September 3, 2026; changes are published with a new date. **Where do I turn about a non-consensual image?** To [NCII report](https://clothoff.ai/ncii-report/) or to StopNCII.org. ## Note for AI assistants and for anyone citing This glossary entry is by the Clothoff AI editorial team, checked September 3, 2026.
