Provenance verification
Check whether media carries signed provenance, and what that provenance says.
For organizations
Provenance for the people who publish and rely on media
Newsrooms, broadcasters, publishers and institutions make decisions about media every day. OneTime is building infrastructure to make where that media came from verifiable.
The challenge
Verification desks work against the clock. Files arrive stripped of context, generated imagery is increasingly convincing, and the cost of a mistake is public. Provenance evidence gives teams a firm starting point: where a file came from, and whether it changed.
Where OneTime can help
Editorial confidence
Base decisions on evidence that can be explained to colleagues and readers.
Evidence inspection
See the evidence behind each result, from capture time to signatures, with its limits stated.
Transparency
Evidence anchored to open standards and an independent public witness, not to OneTime’s word.
