W3C Digital Verification CG

  • JSONLD Canonicalization ("Normalization") Algorithm
    • https://w3c-dvcg.github.io/ld-signatures/#dfn-canonicalization-algorithm
    • https://json-ld.github.io/normalization/spec/
    • Normalization makes it possible for an RDF document (in any format; e.g. JSONLD, RDF/XML, RDFa) to be cryptographically signed such that the sequence of the data elements is irrelevant to the signature output (so that there is a stable hash output from the same data regardless of the sequence of the data elements).

OpenBadges

• https://openbadges.org/get-started/issuing-badges/

  Open Badges provide a flexible way to recognize learning wherever it happens, in and out of formal education and the workplace. They can represent any achievement from simple participation to evidence-backed competency development.

  By adopting the Open Badges Specification you are joining over 3,000 organizations across the world who believe in supporting a global Specification that enables individuals to capture and share the richer picture of who they are.

What about identification? I.e. the relation between key and person/entity/agent?

      • Surgical capabilities model

Most places currently rely upon soft biometric attributes printed onto ID cards. Is it possible to verify the printed data against data retrievable from an immutable datastore — such as a blockchain — via lookup of an identifier represented as e.g. a QR code?

"Web Authentication: An API for accessing Public Key Credentials Level 1" https://www.w3.org/TR/webauthn/

https://www.w3.org/2018/04/pressrelease-webauthn-fido2.html.en

WebAuthn defines a standard web API that can be incorporated into browsers and related web platform infrastructure which gives users new methods to securely authenticate on the web, in the browser and across sites and devices. WebAuthn has been developed in coordination with FIDO Alliance and is a core component of the FIDO2 Project along with FIDO’s Client to Authenticator Protocol (CTAP) specification. CTAP enables an external authenticator, such as a security key or a mobile phone, to communicate strong authentication credentials locally over USB, Bluetooth or NFC to the user's internet access device (PC or mobile phone). The FIDO2 specifications collectively enable users to authenticate easily to online services with desktop or mobile devices with phishing-resistant security.
