Web Technologies for Decentralised Identity
摘要
This chapter analyses technologies that support decentralised identity on the Web. The World Wide Web Consortium, which maintains the technical specifications of the Web, has consistently advocated for decentralised models for sharing information. Some of their latest recommendations include the specification of a Decentralised Identifier (DID) and a Verifiable Credential (VC) following the Semantic Web principles. The claims contained in these credentials can be algorithmically verified without the intervention of authorities. These technologies are often associated with implementing the Self-Sovereign Identity paradigm, and this chapter evaluates whether this will happen in practice, particularly in the context of the financial sector. Whereas some privacy concerns are identified, the integrated use of DID, VC and Open Digital Rights Language ODRL will present clear benefits in at least some commercial settings.
