mintBlue is event streaming with privacy-enhancing technologies built in. Connect the systems you already run, inside and between organisations.
Each field has its own key.
Tax, fraud, identity and supply-chain data, for government and industry.
Real-time VAT verification, built with the Belastingdienst.
“mintBlue turned our nightmare of invoice exchanges into a dream of automation. Now we strive to make taxation less of a headache for everyone involved.”
A bank, a payment provider, a webshop, a parcel carrier and the police share fraud signals, and the origin of every signal can be proven.
Passport photo origin, from the studio's device to the municipal counter, with no central collection of photos.
A blueprint for warm referrals: fraud victims report once, and with their consent the story travels to each organisation that helps next.
“We have wanted to share data between our fraud portals for a long time. I did not think it could be done, but with mintBlue it simply can!”
Emissions data across a multi-party supply chain, with each partner keeping its own data.
“This partnership with mintBlue accelerates our vision of making maritime logistics more efficient and environmentally responsible. Together, we set new standards for sustainability and transparency in the supply chain.”
How it connects
Your systems keep doing their job. mintBlue runs next to them, shares what other departments and organisations need, and proves every exchange.
It runs next to the databases and business systems you already have, picks up the changes you choose to share and signs them at the source.
Encrypted per field, changes travel peer-to-peer to whoever is entitled to them, with no broker or hub you have to trust.
Who shared what, with whom, when and on which mandate is recorded in a tamper-evident audit trail that an auditor or supervisor can check afterwards without opening the data.
The same event stream carries all three. Start with selective disclosure, give auditors and supervisors their own view, and compute across organisations without pooling data.
01
Share only what is needed. With a key per field, each department or organisation opens only the facts it is entitled to, such as a yes or a no.
02
Prove what happened. Every exchange lands in a tamper-evident audit trail that auditors and supervisors can check in real time, without opening the data.
03
Compute together without pooling data. Organisations learn whether they hold the same case, and a match only shows when enough of them hold it.
For data that moves between departments and organisations and has to stay private and provable.
Built in Europe, for Europe
mintBlue is built on open protocols that anyone can adopt and nobody owns, ourselves included. That is how a country keeps its data under its own law, a company stays in control of its own systems, and a person can decide what is shared about them.
Most of the Western world's data sits on American infrastructure, exposed to CLOUD Act subpoenas, and a European cloud only moves that dependency. mintBlue removes it: your systems and keys can stay with you, and we are a European company with no parent company outside Europe.
Under European law
