What is proof of existence?
Proof of existence is evidence that a specific digital fingerprint existed at a specific time. OriginProof creates that record with a SHA256 hash, timestamp, Proof ID, certificate, and verification page.
How does SHA256 work?
SHA256 turns file or text input into a fixed fingerprint. The same input produces the same hash. If the input changes, the hash changes, which makes it useful for verification.
Do you store files?
No. Files are fingerprinted locally in your browser, so in modern browsers the file itself is never uploaded to OriginProof. Only proof metadata is stored: the SHA256 hash, timestamp, Proof ID, source context, creator metadata, and visibility settings.
Can OriginProof verify ownership?
No. OriginProof records proof of existence. It does not verify ownership, authorship, copyright, legal rights, or who created the content first in a legal sense.
How does verification work?
A verification page displays the Proof ID, timestamp, SHA256 fingerprint, status, and related metadata. A file can be compared against the stored fingerprint to check whether it matches.
What is a Proof ID?
A Proof ID is the public reference for a proof record, such as PR-8F3A2D71. It is used in verification links, certificates, badges, and creator profiles.
Can I register text instead of a file?
Yes. You can paste text directly, such as an idea, prompt, code snippet, concept note, or specification, and register a proof from that text.
What happens if the same content is registered twice?
OriginProof can show duplicate registration context. The earliest timestamp for the same fingerprint is the strongest proof of existence record in the registry.
