How is re:claimID different from<insert other identity provider service here> ?
Unlike most other identity provider services, re:claimID is not operated by a single service provider or even a federated consortium of service providers. Instead, it is a fully decentralised service operated implicitly by its users. Consequently, large-scale data monetisation, mass-surveillance and other (ab)use of personal data is inherently mitigated.
How much does re:claimID cost?
re:claimID is Free Software. We argue that in order for an identity system to be a credible solution for self-sovereign citizens to exercise their right to digital self determination, open and free software as well as services are indispensible.
How does re:claimID work?
re:claimID uses the GNU Name System as identity and attribute directory service. In order to allow the user to enforce access control decisions, we use a cryptographic access control layer. However, the user is not required to manage any cryptographic keys or manage zones in a namespace. This is done under the hood by re:claimID.
How does a website know the attribute data share via re:claimID is correct?
Short answer: It doesn't.
Long answer: Identities are initially self-asserted by the user. re:claimID could, however, also be used to share third party attested attributes (e.g. X.509 certificates). Further, have integrated Privacy-ABCs for this use case.
Who is behind re:claimID?
re:claimID was initially developed at Fraunhofer AISEC and is part of GNUnet.
