Our technology

The power of math and blockchains combined

To invalidate our Digital Witnesses™, your first step would have to be to argue that math is wrong. And it's uphill from there.

The basic premise of the evidence we create is that we mathematically bind three pieces of information together: WHAT, WHEN and WHO.

The WHAT part is the content in question. It can be a file, a document, a database entry, a picture, a transaction record or any other digital datapoint. Basically, any type of digital information can be used, and even the most minute difference between two versions will be detected and logged.

The WHEN is the exact time and date the data was logged. This information is encoded in such a way that it becomes part of the evidence; had the logging happened at any other point in time, the algorithms would have generated a different result.

The WHO part is your company's name, or any other moniker that you choose to assign as a signature to the document. The signature is also encoded into the evidence, so that it's possible to prove mathematically that any other combination of data, timestamp and signature would have generated a different result when acted on by our algorithms.

Information is often sensitive, and might be subject to regulatory requirements. That's why we've built our technology in such a way that we don't even have to see your information. The information we require as the WHAT part can be calculated within your systems so that no sensitive information ever leaves your secure environment. We only see the calculated cryptographic hash – like a digital fingerprint – that's created using a one-way function, and they convey no information about the content they represent.

We have a name for the combination of these three pieces of information: a Digital Witness. We think the name is apt, because witnessing data is exactly what they do. If you have created a document and you want to prove that you did so at a certain time, a Digital Witness is precisely what you need.

The final step in our evidence creation chain is to also prove that the Digital Witness itself is valid, and that it has existed for as long as we claim it has. We do that by leveraging blockchain technology, specifically the ledger features that track all transactions that are performed on the chain.

The end result of all this is that you have a Digital Witness that binds the WHAT, the WHEN and the WHO together to prove that you had a certain document at a certain point in time. And you have an immutable blockchain transaction record that proves that the Digital Witness existed at the point in time when the transaction was made. And since it's all based on math, it's really hard to argue with.
