Evaluate evidence in a synthetic-media environment
separate visual inspection, source context, corroboration, and technical provenance
respond to a consequential media claim without amplifying uncertain content
Terms you will use
These definitions prepare you for the reading; you do not need to memorize them.Synthetic media
Image, audio, video, or other media substantially generated or transformed through computational systems, including but not limited to deceptive uses.
Deepfake
Synthetic or manipulated media that convincingly represents a person, event, or identity in a way that can mislead about what occurred.
Content credential
Machine-readable provenance information that can record origin and transformations when participating tools preserve and verify it.
01
The visible artifact is only one part of the evidence
Generated media can be realistic, and authentic media can look strange after compression, cropping, lighting, or editing. Searching for unusual fingers, blinking, shadows, or audio rhythm may suggest questions, but no permanent list of visual defects can serve as a truth detector.
Start with the claim around the media. Who first published it? When and where was it supposedly recorded? Is the account in a position to know? Does the content match known chronology, geography, weather, language, and surrounding events?
02
Use independent context and provenance together
Find the earliest available version, reverse-search key frames or images, and seek independent reporting or primary records from the place and time. Contact the depicted person or responsible institution when appropriate. A derivative repost without context is weaker than an attributable original plus corroboration.
Content credentials can make origin and editing history more inspectable when the chain is present and valid. They do not prove that a staged scene was truthful. Missing credentials also do not prove that media is fake, because many cameras, editors, platforms, and historical files do not preserve them.
03
Your response can reduce or increase harm
Urgent outrage creates pressure to share first. Pause consequential action, save the source and timestamp without redistributing sensitive content, and describe uncertainty precisely. Ask verification organizations or qualified forensic specialists when the stakes justify it.
Be alert to the liar’s dividend: growing awareness of deepfakes can let someone dismiss authentic evidence merely by calling it AI-generated. Apply the same evidence process to claims of authenticity and claims of fabrication. Avoid treating detection software as an infallible judge.

A layered media check
Selected layerClaim and origin
Record the exact allegation, earliest known source, date, place, uploader, and chain of reposts.

Claim and originRecord the exact allegation, earliest known source, date, place, uploader, and chain of reposts.
Context and corroborationCheck surrounding events, independent witnesses, records, alternate angles, and credible reporting.
Technical signalsInspect metadata, credentials, edits, compression, and forensic indicators without treating one signal as decisive.
“A detector score or missing content credential can prove that a video is fake.”
Detection is probabilistic and context-dependent; provenance coverage is incomplete. Combine technical signals with origin, chronology, corroboration, and qualified review.

An unknown account posts a shocking video said to be from a breaking event. What should you do first?
02
A video has a valid provenance credential showing the camera and edits. What does that establish?

Write a synthetic-media verification plan
Choose a hypothetical consequential video or audio claim. List the origin, context, corroboration, technical provenance, expert escalation, and non-amplifying communication steps you would use.

Defines technical standards for recording content provenance and edits; availability and valid credentials do not establish that the depicted claim is true, and absent metadata does not prove fabrication.
