The Datentreuhänder solution is a trusted data trustee service designed to enable the secure and compliant handling of sensitive data. It separates data storage, data processing, and identity information to ensure that data can only be used for approved purposes. The service acts as a neutral intermediary between data providers and data users, enforcing contractual, technical, and organizational rules. It is intended for scenarios where data must be shared or evaluated without exposing identities or raw data, particularly in regulated environments and public‑interest use cases.
