Yes, absolutely. The seed is only required to decrypt the encrypted metadata, which contains details like the author’s full legal name, the SHA-256 hash of their email address, and their declaration of ownership.
That metadata is what makes the proof significantly stronger in more complex or formal contexts, such as litigation, takedown requests, copyright disputes, or legal proceedings. It proves not only that the file existed at a specific time, but also that a specific individual with a full name and email address claimed authorship at that moment. In those cases, the seed enables a much richer and verifiable layer of evidence.
However, even without the seed, anyone can already prove that:
A file existed at a specific date, and
That it was registered immutably on the blockchain.
This is possible because EMOZ stores the file’s hash (fingerprint) and the hashing algorithm in clear text on-chain. So, if someone has the original file and the transaction hash, they can recompute the fingerprint and compare it to what’s recorded in the certificate.
This type of public verifiability is useful for creators who want to add a visible proof of authorship to their work, for example:
A photographer can include a link to emoz.io/verify?... in the copyright section of their gallery,
An illustrator or musician can include the verification link on their website or portfolio,
An academic can do the same when publishing preprints or research.
In short: the public certificate already proves existence and authorship, while the seed makes that proof even stronger by tying it to an individual identity, but both levels are useful depending on the context.
