Andrew Hughes, director of Identity Standards and Pink Identity historical figure in the identity industry, discusses the implementation and challenges of mobile driving licenses, the standards and features of the mobile driving license spec, the PKI and synergies with OpenID Connect, and the future of mobile driving licenses including general purpose wallets, identity verification, privacy concerns, and standardization efforts.
The Mobile Driving License (MDL) is an ISO standard that enables government issuers to provision official driving licenses to a person's mobile device, making digital licenses equivalent to plastic licenses.
The MDL allows individuals to selectively present their identification attributes to different parties, opening up new possibilities for user-centric control and potentially impacting the identity verification industry.
Deep dives
Overview of the Mobile Driving License
The podcast episode discusses the Mobile Driving License (MDL), an ISO standard that has the potential to impact the daily life of everyone. The MDL is a family of standards that enables government issuers, such as departments of motor vehicles, to provision official driving licenses to a person's mobile device in app form. By conforming to these standards, mobile driver's licenses can become equivalent to plastic driver's licenses, recognized by law. The MDL standard is supported by international associations of motor vehicle administrators and is expected to become a dominant structure used by government issuers worldwide. Actual production deployments of MDL apps and issuance services are already taking place in various states.
Functionality and Future Potential of MDL
The MDL represents both an entitlement to drive and a general purpose identification card. As the MDL evolves and integrates into the identity ecosystem, it opens up new possibilities for user-centric control. With MDL, individuals can selectively present their identification attributes, such as name, address, or age, to different parties, unlocking a range of use cases. While plastic cards will likely coexist with digital formats in the foreseeable future, the utility and convenience of digital credentials will drive adoption. The MDL also raises questions about the future of identity proofing services, as government-issued identification credentials could provide high-confidence proofs of identity, potentially impacting the identity verification industry.
Standards and Privacy Considerations
The ISO 18013 part 5 standard covers the data structure, integrity mechanisms, secure session establishment, and data transfer protocols for MDL. The standards are designed to allow the data to be provisioned with signatures to the device itself, ensuring privacy and offline usability. Trust levels, security levels, data attributes, and potential attestation processes are being considered by the ISO workgroups. The MDL standard does not require the credentials to call home for data, but verification software may need to perform revocation checks. MDL represents an opportunity to unlock a new set of use cases while maintaining security and privacy as top priorities, ultimately reshaping how identification credentials are used.
In this episode, we discussed the mobile driving license, an ISO standard that has the potential to have a direct impact on the daily life of everyone. And to do that, I enlisted my old friend Andrew Hughes, director of Identity Standards and Pink Identity historical figure in the identity industry
