Swiss Federal Railway Identity management POC using Blockchain
Linum recently built and implemented a working PoC for the SBB (National Swiss Railway) in Switzerland to provide their railway workers with unique digital identities live on the Ethereum blockchain.
The identities linked to their respective uPort ID’s was then anchored to an identity on the blockchain via their mobile devices. A hash of the worker’s check-in / check-out activities is published to the blockchain so that the internal database can be audited to verify which worker was present and if they were correctly certified to work on that site. The app can also connect to identity systems authorized by city administrations, like Zug ID.
A self-sovereign blockchain-based identity is well-suited for this use case because workers should be able to carry over their identity from one company to another and no specific company should own or manage it. In addition, there are multiple companies and parties issuing certificates.
