Article 49: the EU database for high-risk systems

The Act keeps a public register of high-risk systems. For most businesses this is the provider's job, with one exception for public bodies.

What the database is

The Act sets up an EU-level database where high-risk Annex III systems are registered, so authorities and the public can see what high-risk AI is in use across the Union. It is one of the ways the Act stays transparent about the systems that can most affect people.

The database is largely public, which is part of the point: it lets people and watchdogs see where high-risk AI is deployed, rather than having to trust that someone, somewhere, is keeping track.

Who registers what

The provider registers the high-risk system itself, before placing it on the market, with an entry describing the system and its intended purpose.

Deployers that are public authorities, agencies, or bodies also register their use of such a system. Private businesses generally do not register; they rely on the provider's entry rather than making one of their own.

What it means for you

If you are an ordinary company deploying high-risk AI, registration is mostly the provider's job, so this is background. It is still worth checking that a high-risk system you rely on is properly registered, as a sign the provider has done their part.

If you are a public body deploying high-risk AI, registering your use is one of your own steps. In Veillo it shows up as an external action you confirm once it is done, so it stays on your roadmap until handled.
