Dezentrale Identity Hubs

Von Ralf Keuper

Dass Microsoft intensiv an einer Personal Data Bank arbeitet, war bekannt (Vgl. dazu: Projekt “Bali” – Microsoft arbeitet an einer Personal Data Bank). Nun stellt Alex Simons von Microsoft Azure in Identity Hubs as personal datastores die, wenn man so will, Weiterführung der Idee vor.

Identity Hubs are decentralized, off-chain, personal datastores that put control over personal data in the hands of users. They allow users to store their sensitive data—identity information, official documents, app data, etc.—in a way that prevents anyone from using their data without their explicit permission.

Users can use their Identity Hubs to securely share their data with other people, apps, and businesses, providing access to the minimum amount of data necessary, while retaining a record of its use.

Die personenbezogenen Daten werden dabei außerhalb der Blockchain oder Distributed Ledger – Variante gespeichert. Sie werden über Geräte und Clouds verteilt, so dass kein Single Point of Vulnerability entstehen kann:

A key property of the Hub is the ability to sync and replicate across device(s) and Cloud(s). This means that users can run their Identity Hubs anywhere, with any provider they choose, for instance on Microsoft infrastructure or anywhere else. Such Identity Hubs can sync data across instances to ensure there is no single point of vulnerability. None of the DIF compliant providers would have means to see who is sharing what data and with whom.

Durch die Unterstützung verschiedener Standards wird den App-Entwicklern ihre Arbeit erleichtert:

App developers can leverage existing industry-specific schemas, such as those described at schema.orggs1.org, and hl7.org. If desired, any user or developer can publish a custom schema that apps and services can use to collaboratively store and access data. .. This open semantic data model ensures Hubs can act as generic personal data stores that can flex to accommodate a wide range of data and use cases—including personal info, app data, medical records, etc. 

Identity Hubs in der vorliegenden Form passen womöglich besser zu den Anforderungen der Nutzer wie auch der neuen Infrastrukturen (Blockchain, Distributed Ledger, dezentrale KI, Agententechnologie) als die eher herkömmlichen Personal Data Stores wie Digi.me.
