Apparat’s disclosure register

About this register

This register records verified facts about Apparat itself: its legal entity (Der Apparat, a French SASU), its architecture, its data policies, and the EU AI Act framework it is built for. Every fact is drawn from a public source — the INPI and INSEE company registries, the EU AI Act text, and Apparat’s own published pages.

How it works

Each fact is kept with its source, its verbatim context, and a cryptographic seal computed over six fields: label, value, context, source URL, unit, and time period. The seals are combined into a single commitment, anchored with a timestamp in a public Sigstore Rekor log. Any later change to an entry breaks its seal, so the record is tamper-evident and can be checked by anyone.

Apparat runs this register on itself as a working example of what it builds for its clients. The format and its reference verifier are open, so anyone can inspect how a Data Fidelity Register is structured and verified.

Open source

The reference verifier for the Data Fidelity Register format is open and MIT-licensed. It independently checks each entry seal and the RFC 6962 release commitment: github.com/data-fidelity-register/verifier.
