What we receive
A 64-character digital fingerprint. It can't be turned back into your photo.
Verify a photo
Don't trust us. Check it.
The moment our inspector takes a photo, it gets its own digital fingerprint, sealed together with the exact time and place. That record can't be changed afterwards, so if anyone edits the image, swaps it or copies in a different one, the fingerprint won't match.
Your file never leaves your browser. We only compare fingerprints.
How it works
Three steps, and your photo stays with you
- 01
Download the original
Open any Proof chip on a factory or product page and choose "Download original". That's the untouched file our inspector captured.
- 02
Your browser fingerprints it
Drop it in above and your own browser works out its digital fingerprint. Change a single pixel and the fingerprint changes completely.
- 03
We compare it with the sealed record
We look for that fingerprint among our proof records, which were sealed with the time and place the moment each photo was taken and can't be changed.
Your privacy
