Among the changes is a new identity proofing option that doesn’t use biometrics like facial recognition.
NIST has a new draft out of a long-awaited update to its digital identity guidelines.
Published Wednesday, the standards contain “foundational process and technical requirements” for digital identity, Ryan Galluzzo, the digital identity program lead for NIST’s Applied Cybersecurity Division, told Nextgov/FCW. That means verifying that someone is who they say they are online.
The new draft features changes to make room for passkeys and mobile drivers licenses, new options for identifying people without using biometrics like facial recognition and a more detailed focus on metrics and continuous evaluation of systems.
The Office of Management and Budget directs agencies to follow these guidelines, meaning that changes may be felt by millions of Americans that log in online to access government benefits and services. The current iteration dates to 2017.
NIST published a draft update in late 2022 and subsequently received about 4,000 line items of feedback, said Galluzzo. NIST is accepting comments on this latest iteration through October 7.
The hope is to get the final version out sometime next year, although that timeline is dependent on the amount of feedback the agency receives, he said.
Among the changes are new details about how to leverage user-controlled digital wallets that store mobile drivers licenses to prove identity online. NIST also added an existing supplement around synchable authenticators, or passkeys, issued earlier this year into the digital identity guidelines.
The latest draft also features more changes around facial recognition and biometrics, which have often been the subject of debate and controversy in government services bound to these guidelines.
Changes meant to offer an identity proofing option that doesn’t involve biometrics for low-risk situations comprised a big focus of the 2022 draft update.
NIST tinkered with that baseline further in the latest draft after it got feedback that the standard still had “a lot of friction for lower- to moderate-risk applications,” said Galluzzo.
NIST also added a new way to reach identity assurance level 2 — an identity proofing baseline that is currently met commonly online using tools like facial recognition — without those biometrics.
Instead, organizations could now send an enrollment code to a physical postal address that can be verified with an authoritative source, said Galluzzo, who added that the authors also tried to streamline the section to make it clear what the options are, with and without biometrics.
The latest draft also has an updated section explaining four ways to do identity proofing, including remote and in-person options with or without supervision or help from an employee.
Other changes in the latest draft include specific recommended metrics for agencies to use for the continuous evaluation of their systems.
That focus aligns with the addition of performance requirements for biometrics added in the 2022 draft, as well as a push for agencies to look at the potential impact of their identity systems on the communities and individuals using them, as well as their agencies’ mission delivery.
“Our assurance levels are baselines, and you should be… focusing on the effectiveness of the controls you have in place because you might need to modify things to support your risk threats profile or to support your user groups,” he said.
The latest draft also features new redress requirements for when things go wrong.
“You can’t simply say, ‘Look, that’s a problem with our third-party vendor,’” said Galluzzo.
Big-picture, weighing the views of stakeholders that prioritize security and others focused on accessibility is difficult, he said.
“Being able to take those two points of view and balance those into something that is viable, realistic and implementable is where the biggest challenge is with identity across the board,” said Galluzzo.
That tension came into the forefront during the pandemic, when many government services were pushed online.
In the unemployment insurance system, for example, many states installed identity proofing reliant on facial recognition when they faced schemes from fraudsters.
The existing NIST guidance doesn’t offer many alternatives to biometrics for digital identity proofing, but facial recognition has increasingly come under scrutiny in regards to equity, privacy and other concerns.
The Labor Department’s own Inspector General warned of “urgent equity and security concerns” around the use of facial recognition in a 2023 memo, pointing to testing done by NIST in 2019 that found “nearly all” algorithms have performance disparities based on demographics like race and gender, as a NIST official told lawmakers last year. That varies depending on the algorithm, and the technology has also generally improved since 2019.
Jason Miller, deputy director for management at the Office of Management and Budget, said in a statement that “NIST has developed strong and fair draft guidelines that, when finalized, will help federal agencies better defend against evolving threats while providing critical benefits and services to the American people, particularly those that need them most.”
The White House itself has also been handling these tensions as it’s been crafting a long-awaited executive ordermeant to address fraud in public benefits.
“Everyone should be able to lawfully access government services, regardless of their chosen methods of identification,” said NIST Director Laurie Locascio in a statement. “These improved guidelines are intended to help organizations of all kinds manage risk and prevent fraud while ensuring that digital services are lawfully accessible to all.”
