Cornerstones of a Future Solid B2B Ecosystem: Authorization App and Rights Delegation Proxy

The Solid framework for decentralized and self-sovereign data management proposed by Berners-Lee enables dynamically binding an identity to a Solid application and a user-specific Solid data store, thus enabling interoperability within the Solid ecosystem. We evaluated Solid in the context of a typical B2B use case, the granting of a loan between a bank and a receiving company, and thereby identified two business functionalities that are particularly relevant in the B2B context: The need to provide secure and easy access to internal data between companies and the need for employees to be able to take on different roles in business processes depending on whether they are acting internally or externally (i.e., on behalf of the company). We transferred these business requirements into two separate applications, the “Authorization App” and the “Rights Delegation Proxy”, and evaluated them based on our use case.
