Full Title or Meme
Mobile Driver's License Presentation maps ISO 18013-5 wallet presentation to DIF Presentation Exchange.
Context
- The DIF Presentation Exchange is looking for test cases. This is such a test case (ie a use case with teeth).
- This use case looks at the wallet as the source of Presentation Statements, which is not necessarily the full scope of the DIF WG.
Actors
- Holder = The entity that submits proofs to a Verifier to satisfy the requirements described in a Presentation Definition (may or may not be the subject)
- mDL holder = individual to whom an mDL is issued = legitimate holder of the driving privileges reflected on an mDL = subject of the mDL
- Verifier = The entity that defines what proofs they require from a Holder (via a Presentation Definition) in order to proceed with an interaction.
- mDL verifier = entity using an mDL reader to verify an mDL
- Issuing Authority = trusted signer of data elements
Transaction
- The holder and verifier establish a session
- The verifier asks for mDL data
- mDL send data by value or by reference
- The verifier may or may not request other data
- Transport can be by various NFC or QR code.
- Format is CBOR - represented here as json.
