Know where data came from.

A signal, a photo or an emissions figure is only useful if the next party knows who created it and that nobody changed it. mintBlue signs it at the source; the record stays with its holder and no central database is needed.

Know where data came from.

Organisations we have built with

Belastingdienst
Dockflow
Ministry of Justice and Security
VISMA
National Office for Identity Data
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!

How it connects

From signal to proof in three steps

Each organisation keeps its own data. Only the signal travels, signed by whoever shared it.

  • 01

    A connector in your own environment

    It runs next to the systems where your fraud cases are handled today, picks up the signals you choose to share and signs them at the source.

  • 02

    An event stream between organisations

    Signals travel peer-to-peer to the organisations entitled to them, encrypted for them, with no broker or hub you have to trust.

  • 03

    Certainty for every decision

    The receiver acts on a signal it can trust: it knows who sent it and that nobody changed it. The tamper-evident audit trail lets a supervisor check the exchange afterwards.

Why neither a central database nor manual sharing works

Manual sharing keeps data private, but each organisation only sees its own piece. A central platform sees everything, but every participant has to hand its data to one operator. mintBlue lets signals flow between organisations as they happen, with proof of who shared what, when and on which mandate. Organisations can also learn that they hold the same case by matching on blinded tokens, without exchanging lists.

Sharing signals with proof of origin removes that trade-off.

Manual Processes & Centralised Platforms

  • Each organisation sees only its own fraud signals
  • Either nothing is shared, or one operator sees everything
  • Who shared what, and on which mandate, is hard to reconstruct afterwards.
  • Does not scale. More authorities means more bilateral agreements and more overhead.

mintBlue

  • Signals shared between organisations, each signed by the organisation that shared it.
  • Only the signal travels; the case file stays at the source.
  • A tamper-evident audit trail of who shared what, when and on which mandate.
  • Scales with the number of participating organisations.
