Free proof-of-creation certificate for your photos (SHA-256 + camera date)

Get a dated certificate for an original photo: its SHA-256 fingerprint, the camera date stored in the file, and a public record of when the fingerprint was registered. Your photo never leaves your device.

What the certificate proves

• The fingerprint (SHA-256) identifies this exact file. Any later edit changes it.
• The camera date (EXIF) is what your camera or phone wrote into the file. It's useful evidence but can be edited, so treat it as supporting detail.
• The registration date is when MakerSentry's server first recorded this fingerprint. Anyone can check it later with the verify box on this page — that's the part a copier can't backdate.

Your photo is fingerprinted in your browser; only the fingerprint and camera date are sent to us. Keep the original file safe: the certificate is only useful alongside it.

Questions

Is this legally binding?

It's evidence, not a legal registration. It shows the file existed by the registration date, which is what marketplaces usually ask about in disputes.

What if someone registers my photo before me?

They'd need your original file to produce the same fingerprint. A copy taken from a website is a different file with a different fingerprint.
