Stamp media
Stamp it as it's taken.
Take a photo or choose a file. It is fingerprinted and signed in this browser, then registered onchain, where anyone can check it.

A device key signed this file's fingerprints and the chain recorded them at the time shown.
Nothing checked the device or the capture, so where the file came from rests on the uploader's word. It also cannot rule out a photo of a screen, a print or a staged scene.

About this browser's key
This browser holds a signing key that cannot be exported. Clearing this site's data deletes it. The next stamp then enrols a new key, and stamps made earlier stay registered.
A browser key can make up to 10 stamps per day.
