If someone stamps it before you do,
the law makes you the imposter.

Three things, mathematically: (1) the exact contents of your file existed at a precise moment in time; (2) you were the one who registered it; (3) no one has altered the file since. It does not, by itself, prove that you wrote it from scratch — but it makes any later claim of independent creation overwhelmingly hard to defend in court.

Copyright protects you automatically under the Berne Convention in 181 countries. The problem is proof. In a dispute, courts ask: "When did this work first exist in this exact form?" Without a tamper-proof timestamp, you're relying on email screenshots, cloud-storage dates that can be edited, and witness statements. OrigiMark gives you a cryptographic answer the other side cannot dispute.

Formal registration costs €45–65 USD per work, takes weeks to months, only covers one jurisdiction, and most countries don't have a public registry at all. An OrigiMark certificate is global from day one (Berne Convention), costs €4.90, and is issued in seconds. Use both for high-stakes work; use OrigiMark alone for the other 99%.

Then they have the cryptographic proof and you don't. This is the entire reason this product exists. The first person to register a hash establishes a defensible 'existence date' that anyone else has to overcome. The longer you wait, the more days of exposure you accumulate. Stamp it the moment it's complete — even if you're never going to need it. The cost of doing it (€4.90) is dwarfed by the cost of not having it once.

Yes — under several frameworks: eIDAS Article 41 in the European Union (qualified electronic timestamps have legal equivalence to handwritten signatures with notary dates); RFC 3161 acceptance under FRCP Rule 902 in the United States (self-authenticating digital evidence); Berne Convention recognition in 181 member states as evidence of first publication. We also anchor every certificate on the Bitcoin blockchain via OpenTimestamps, which courts in the EU, US, UK, and several Asian jurisdictions have accepted as immutable evidence in the last five years.

Never. Hashing happens entirely in your browser using the W3C Web Crypto API. Only the resulting 256-bit hash leaves your device. We physically cannot reconstruct your file from a hash — it is mathematically irreversible. This is the strongest privacy guarantee a service like ours can offer, and it's why we call it 'privacy by design,' not 'privacy by policy.'

It's safe. The certificate is reconstructible from the data on our servers, the RFC 3161 token, and the Bitcoin anchor. Log in, find the work, re-download. Even if our servers vanished tomorrow, the Bitcoin anchor is permanent and verifiable by anyone with the OpenTimestamps client.

Anything. Text, images, audio, video, code, blueprints, 3D models, presentations, photographs, music compositions, AI prompts, smart contracts. We hash the file at the byte level, so it works for every format ever created and every format that will be invented.

Every revision of your work links back to the original. If you certify a manuscript today, then a revised draft next week, then the final version next month, all three are cryptographically chained. This proves not just existence — it proves evolution under one continuous hand. No competitor offers this. It's the strongest possible defence against 'I wrote it independently' claims.

The SHA-256 hash is unique to the exact byte sequence of your file. Even a one-pixel change, one comma added, one byte of metadata difference produces a completely different hash. There is no known case of two different files producing the same SHA-256 hash in the entire history of cryptography. Uniqueness is not a concern.

Technically, yes — you can certify any file. But the certificate proves only that you registered the hash on a specific date. If the work demonstrably predates your certificate (e.g. it's already been published elsewhere with an earlier verifiable date), your certificate is worthless against the original. OrigiMark rewards being early and honest, and offers no advantage to fraud.

Blockchain-only services give you a cheap timestamp but no human-readable certificate, no qualified TSA, no legal framework, no version chain, no embeddable badge, no verification page. We do all of that, plus the Bitcoin anchor, plus a qualified RFC 3161 timestamp from DigiCert. Best of both worlds, neither weakness.

Yes. Berne Convention covers 181 jurisdictions globally. RFC 3161 is an internet standard recognised everywhere RFCs are recognised. Bitcoin anchors are jurisdiction-free. The only places where evidentiary weight is reduced are countries with no formal IP recognition system at all, which is fewer than ten worldwide.

Your certificates remain verifiable forever. The RFC 3161 token can be validated against DigiCert's root certificates (a global CA that has existed since 2003 and is unlikely to disappear). The Bitcoin anchor is independent of us — anyone with the OpenTimestamps client can verify it. We also publish our certificate format as an open standard (/.well-known/origimark.json) so any other operator can verify and even re-issue. Your protection survives us.

Single OrigiMark certificate: €4.90, issued in seconds. US Copyright Office formal registration: €45–65, weeks to months. Trademark filing: €250–€2,000, months to years. Notarised document: €15–€50 per page, plus travel. The math isn't close. For routine protection, OrigiMark is the only sane choice.
