Record what you have.
Submit the exact text of your work. The service encrypts it and records a digital fingerprint in a linked ledger.
EVIDENCE BEFORE CLAIMS
Original thinking.
A verifiable record.
Give your research or invention a clear digital record. Seal the exact text, keep its unique fingerprint, and look for related work — without publishing your content.
For researchers, inventors & patent professionals.

You keep creating. Keep the evidence organized alongside it.
Keep your evidence.
Save your receipt and one-time reveal key immediately. Your key is not recoverable through the platform.
Check. Compare. Review.
Look up a fingerprint, inspect the public ledger, or opt in to monitoring for potentially related research.
01 / CONFIDENTIAL RECORD
Document the work.
Keep the details sealed.
A private text deposit, a SHA-256 fingerprint, and a downloadable receipt. Public author and title fields are your choice, not the default.
02 / RESEARCH MONITORING
Follow related work.
Review what matters.
Compare opt-in deposits and search Crossref scholarly metadata. Similarity scores are leads for careful review, never infringement verdicts.
CLARITY IS PART OF THE SERVICE
Know what your
record establishes.
Useful evidence starts with precise boundaries. A deposit does not grant a patent, establish ownership, or decide infringement.
- A content fingerprint
- Lets you check whether exact text or file bytes match a recorded hash. It does not identify who created the work.
- An independent time bound
- A verified third-party RFC 3161 checkpoint supports existence by the TSA’s signed time. An earlier server timestamp is not independently attested. How to verify it.
- A similarity result
- Points to potentially related material within the sources searched. It is not proof of copying or a legal conclusion.
BEFORE YOU BEGIN
A few important details.
Does a deposit make my invention public?
Not by default. The public ledger shows the fingerprint and event information, while the deposited text is encrypted at rest. Publishing your author and title is optional. A later reveal makes the exact text public and is irreversible. Public metadata, content length, and guessable hashes can still disclose information.
Where does encryption happen?
On the server, after you submit text over HTTPS in a correctly configured deployment. This is not client-side or zero-knowledge encryption. The deposited text is encrypted at rest; private titles and account metadata are stored separately. Only the local fingerprint calculator keeps your selected file or text entirely on your device.
Is the timestamp independently verified?
Only after a valid external RFC 3161 checkpoint covers your deposit. The deployment uses a third-party RFC 3161 time-stamp authority chosen by the operator, and a background worker; until a request and its signature are successfully verified, your record remains pending. The signed TSA time is an upper bound on existence, not an attestation of the earlier server-clock time. Download and independently verify your inclusion proof.
What does research monitoring cover?
Crossref scholarly titles and abstracts where available, and deposited works whose owners opted in to comparison. It does not search every patent, repository, or website. MinHash is a text-similarity method and can miss related ideas or flag unrelated work. Scheduled scanning requires the optional worker service.

Inspect linked events and content fingerprints without accessing sealed text. Public metadata is shown only when the depositor chooses to share it.

INDEPENDENT TIME EVIDENCE
External timestamp receipts
The TSA-signed time is separate from server capture time. Export receipts, or use public lookup for a deposit inclusion proof. Verify independently with OpenSSL.
Loading recorded receipts…
Local integrity is not independent proof of time. An operator can rewrite an entirely unanchored history. Check exported third-party receipts independently.
PUBLIC VERIFICATION · NO ACCOUNT NEEDED
Verify a fingerprint.
Have a SHA-256 hash? Look it up in the public ledger. Have the original file or text? Calculate its fingerprint on your device first.
Search the public ledger
Only the fingerprint is sent for lookup, not your source content.
Ready when you are.
Matching events and their external-anchor coverage will appear here.
OPTIONAL FIRST STEP
Calculate on your device
Your selected file or pasted text is not uploaded by this calculator.
Calculates the hash of the file’s exact bytes. A file takes precedence over pasted text.
or use exact text
Whitespace and line breaks affect the result. For a text deposit, use the exact text you submitted, not a formatted document file.
Calculated fingerprint
The result also fills the lookup field. Choose “Verify in ledger” to search.
INTERPRET THE RESULT CAREFULLY
A match is not an ownership claim.
Matching a content hash supports byte-for-byte equality, not authorship, ownership, patent rights, or infringement. A local audit alone cannot prevent an operator from rewriting an entire unanchored history. Independently verify any third-party time receipts.
