authenticity
Definition
The quality of having an objectively verifiable origin ; contrast veracity. When a newspaper publishes a story about an event, every faithful reproduction of that story may be authentic — but that does not mean the story was true (has veracity).
Authenticity is strongly related to digital security. Ideally it should be verifiable (to a root-of-trust). The future picture therein is the Authentic Web.
