Support Verifiable Credentials
The iSHARE Framework supports Verifiable Credentials (VCs) to enhance trust, interoperability, and portability within and across data spaces.
This capability aligns iSHARE with global standards defined by the W3C Verifiable Credentials Data Model 2.0, enabling participants to exchange digitally verifiable and privacy-preserving claims in a secure, standardised manner.
Integrating VCs as a global standard enhances decentralised identity and trust, already a foundation in iSHARE, to ensure digital credentials can be verified cryptographically without depending on a central authority.
Benefits
Interoperable trust: Credentials issued once can be used across multiple ecosystems as they are all based on the common standard.
Decentralised verification: As has always been the case with iSHARE with VCs as well, no central authority is required for validation.
Privacy: Using VCs could potentially be more privacy-preserving, as no real-time checks are necessary. Also, it supports the sharing of only relevant attributes via the means of Verifiable Presentations
Hybrid compatibility: Works alongside current API-based mechanisms
Example Scenario
A Service Consumer wants to access a dataset from a Service Provider in a mobility data space.
The Participant Registry issues the Service Consumer a Participant Credential confirming it is an iSHARE-adhering organisation.
The Authorisation Registry, on behalf of an Entitled Party, issues the Service Consumer a Data Rights Credential that states it can read specific transport data.
The Service Consumer stores both credentials in its wallet.
When requesting data, the Service Consumer presents these Verifiable Credentials to the Service Provider.
The Service Provider verifies the credentials and grants access if the rights are valid.
This entire process remains secure and verifiable, ensuring that both sides trust each other without prior arrangements or manual validation in line with iSHARE's principles.
