When I was in New York a couple of months ago I had to visit a couple of different buildings for various meetings. At the first building, I was asked for identification. As I am English and not North Korean, I don’t carry identification papers with me when I walk down the street and my British passport and British driving licence (neither of which the security guard could have verified even if I had shown them to him) were locked up securely back in the hotel safe. I presented my standard US identification document. This an old building pass from the previous Consult Hyperion office in midtown. It expired a couple of years ago, but it has my picture on it and it says “David Birch”. It was accepted without question and I was allowed in.
When I went into a second building on that same day, I was asked to scan my driver’s license! They had a scanner on the counter to read the barcode on the back of US driver’s licenses. Obviously I don’t have a US driver’s license, so I showed them my expired building pass again, I was given entry to the building.
If I did have the US driver’s license, then there’s no way I would have let them scan it.
Apart from the obvious fact that my ability to drive is unrelated to whether I have been invited to a meeting or not, nothing that is on my driving licence (except perhaps my name, which had already told the guy on the desk) is any of their business and by handing over my personal information to yet another random database held by yet another random company, I was vastly increasing the chance of my licence data and my personal details being being stolen.
It’s amazing how the driving licence has become an identity document and how machine-readable driving licences have become a vector for collecting personal information. One of my favourite stories about this relates to an experiment done in Washington state, in which researchers hooked up the driving licence scanner to a display over the door. As patrons entered the bar, their personal data was displayed above them for all to see! I imagine having your name, date of birth, address, height and weight displayed the moment you enter any establishment.
Why is this still going on? We live in a world of laser beams and robots on Mars, a world of digital signatures and blockchains. Why are we displaying data to people who don’t need it (or deserve it) instead of
The first steps are already being taken. Consider this example taken from the IEEE Spectrum magazine: “A young woman sits at a bar on Bourbon Street in New Orleans and orders a beer. The bartender asks for identification. The bar patron pulls out her phone, clicks on an app, and displays a digital version of her driver’s license showing she is over 21. In response, the bartender pulls out her own phone, clicks on the same app, uses it to scan the woman’s digital license, and verifies that her information is legit”.
(I was beyond excited to discover than Louisiana is implementing a version of the “psychic ID” that I set out back in 2005!. [Here’s a paper about it from 2009.])
All of which explains why I am very interested in machine-readable driving licences (mDLs) and how we might use them to deliver population-scale identity. The ISO standard for mDLs is ISO 18013. It creates a common basis for general use and mutual recognition of the IDL without impeding individual countries/states in applying their privacy rules and national/community/regional motor vehicle authorities in taking care of their specific needs. and it is five parts as follows:
-
Guidelines for the design format and data content of an ISO-compliant driving licence (IDL) with regard to human-readable features.
-
Machine-readable technologies.
-
Access control, authentication and integrity validation.
-
Associated test methods.
-
Global interoperability.
So, ISO 18013-5 is the new global interoperability standard. Could digital driving licenses evolve into one form of global identity? Actually, I think the answer to this is yes, because ISO 18013-5 includes provisions for extensions to the data model to permit specific “regional” additions to the standard data (e.g., REAL ID across just the USA).

The American Association of Motor Vehicle Administrators (AAMVA) published a useful white paper on “Mobile Drivers’ License Functional Needs” a couple of years ago.

AAMVA Director of Identity Management Geoff Slagle said he does not believe there will be wide scale adoption of the digital licenses by either states or citizens anytime soon because:
· No standards are currently in place for the actual DDL and how it will be used on the smartphone.
· Equipment capability for law enforcement to use during traffic stops needs to be standardized.
· Consumer apprehension over technology and privacy concerns will continue.
