Real-Time ID Check is not only adept at matching photos, it’s smart enough to detect anomalies or changes in a driver’s appearance, such as whether a driver now sports a beard, even though his official Uber photo shows him without one.
“If a driver’s photo doesn’t match, Real-Time ID Check recognizes that it may be because they’re wearing glasses or a hat” in their selfie that day, says Joe Sullivan, Uber’s chief security officer. “So it will ask them to remove their sunglasses and retake the photo.”
Over the last few months, Uber did a test run of Real-Time ID Check with more than 50,000 drivers in various cities across the U.S., where the feature will be rolled out first.
Among the things Uber learned from testing: “Taking a selfie at night is really, really hard,” says Kovalev. “So we rebuilt our entire user interface (UI) so that it’s a very bright UI,” almost acting like a front-facing flash, “making it easier for partners to verify when they’re going online at night.”
And it’s important that drivers stay safe while taking their photos. That’s why the driver selfie must be verified before he or she can access the platform, preventing any picture taking while driving.
Microsoft Cognitive Services was “very responsive” to Uber’s needs, Kovalev says. The original API supported 1,000 users, “and we basically asked, ‘Hey, can we make that a million?’” and the Microsoft team working on the project “didn’t blink,” he said.
“The other part that was helpful through the API is that there wasn’t a standard requirement for the type of photo” to be sent, with drivers sending photos from cellphone cameras with different screen sizes, resolution and aspect ratios.
“There wasn’t a strict requirement to say that it had to be a certain size – there was a minimum, but it was fairly easy to meet that minimum,” Kovalev says. “It wasn’t like, ‘Hey, you have to have this kind of photo to compare only against this type of photo.’ And it didn’t really matter whether it was Android or iOS, or whatever capture device they were using to compare that photo against,” which made the API development faster, with that flexibility being “something we were definitely looking for.”
Andrew Shuman, corporate vice president of products for the Technology and Research team at Microsoft, says the API used for Real-Time ID Check is one of Microsoft Cognitive Services’ REST APIs, designed to give developers the ability to tap into high-quality technologies with just a few lines of code.
“We have expressly developed our APIs to be easy to use, regardless of which platform or language the developer chooses,” Shuman says. “The algorithms are high quality, tested and based on 25 years of Microsoft Research.”
Says Sullivan of Uber: “Excellent security is frequently almost invisible,” And Real-Time ID Check is an example of that, he says.
