For researchers, designers, inventors and R&D teams
When someone claims they had it first, show that you had it, on a date nobody can move.
A design copied, a dataset disputed, a former partner claiming an idea. The quickest way to settle it is to show the exact file was in your hands by a certain date, without having had to publish it.
- When it is tested
- A dispute with a former partner or employee; a design or copyright dispute; a trade-secret case; a question of who contributed what in a collaboration.
- What you will be asked for
- Evidence that a specific document, design, dataset or piece of code existed, unchanged, by a given date, and that it was in your possession then.
- What goes wrong today
- File dates are trivially changed, emails can be edited and forwarded, and publishing something to prove its date gives it away.
- What changes
- Seal the file’s fingerprint and keep the file private. The date rests on our signed log, two independent time-stamps and a Bitcoin anchor, not on your word.
Sealing shows that a record existed unchanged from a given moment; whether your records are enough is yours to judge. A seal is not a patent or a registered design and gives no exclusive right; it is evidence that a file existed unchanged by a date.
Try it in two minutes
- Choose a real file of your own: a notebook page, a design file or a dataset. It is read in your browser and never uploaded.
- Seal it on Seal a file. A free sandbox key is issued on the page; only a salted fingerprint reaches the log.
- Make a copy, change one character in it, and check both against the receipt at Check. The copy fails; the original passes.
