Further Information

"Self-Sovereign Identity" (SSI) refers to digital identities that are under full control of the users and are managed in a decentralised fashion.

Typically based on Decentralised Identifiers (DIDs) on Distributed Ledger Technologies (DLTs), these identities are issued so-called Verifiable Credentials (VCs), a digitally signed document that certifies specified properties of some identity. For such Verifiable Credentials to be useful at all, they need to be useable for some purpose, for example, to gain access to some website on the Web. For example, a student receives a Verifiable Credential from its University that certifies that the student is enrolled in some course on the Web. Then, access to the course material, which is available on the Web, is granted if the student can provide such a credential of enrollment.

For the Web-side of things, we use Solid (, which aims to re-decentralise the Web by empowering the user to take over control again. The Solid Protocol connects mature Web technologies like the Resource Description Framework (RDF) and RESTful HTTPS APIs: Users store data in personal online data storages (Pods) and define access control on their resources as desired.

In this thesis, you will investigate how different DLT-based implementations of SSI can be made seamlessly interoperable with a Web where the user has regained control.
