Amazon's Latest Gimmicks Are Pushing the Limits of Privacy

At the end of September, Amazon debuted two especially futuristic products within five days of each other: a small autonomous surveillance drone, called Ring Always Home Cam, and a palm recognition scanner, called Amazon One. "Both products aim to make security and authentication more convenient -- but for privacy-conscious consumers, they also raise red flags," reports Wired. From the report: Amazon's latest data-hungry innovations are not launching in a vacuum. The company also owns Ring, whose smart doorbells have had myriad security issues and have been widely criticized for bringing unprecedented surveillance to traditionally semi-private spaces. Meanwhile, the biometric data that Amazon Go will collect is particularly sensitive, because unlike a password you can't simply change it if a hacker steals it or it gets unintentionally exposed. Amazon has a strong record for maintaining the security of its massive cloud infrastructure, but there have been lapses across the sprawling business. The stakes are already phenomenally high; the more data the company holds the more risk it takes on. "Amazon has a major genomics cloud platform, so maybe they hold your DNA and now they're going to have your palm as well? Plus all of these devices inside your house. And your purchase history on Prime. That's a lot of information. That's a lot of personal information," says Nina Alli, executive director of Defcon's Biohacking Village and a health care security researcher. "When you give away this data you're giving a company the ability to access and manage you, not the other way around."[...]Additionally, while companies like Apple and Samsung have brought biometric fingerprint and face scanners to the masses by making sure the data never leaves the device, Amazon One takes the opposite approach. Kumar writes that "palm images are never stored" on Amazon One itself. Instead they are encrypted and sent to a special high security area of Amazon's cloud to be converted into "palm signatures" based on the unique and distinctive features of a user's hand. Then the service compares that signature to the one on file in each user's account and returns a match or no match answer back down to the device. It makes sense that Amazon doesn't want to store databases of people's palm data locally on publicly accessible machines that could be manipulated. But the system could perhaps have been set up to generate a palm signature locally, delete the image of a person's hand, and send only the encrypted signature on for analysis. The fact that all of those palm images will be going for cloud processing creates a single point of failure. "I'm worried that people could read your palm vein pattern in other ways and construct an analog. It's only a matter of time," says Joseph Lorenzo Hall, a longtime security and privacy researcher and a senior vice president at the nonprofit Internet Society. "Both the home drone and the palm payment are going to rely heavily on the cloud and on the security provided by that cloud storage. That's worrying because it means all the risks -- rogue employees, government data requests, data breach, secondary uses -- associated with data collection on the server-side could be possible. I'm much more comfortable having a biometric template stored locally rather than on a server where it might be exfiltrated." An Amazon spokesperson told WIRED, "We are confident that the cloud is highly secure. In addition, Amazon One palm data is stored separately from other personal identifiers, and is uniquely encrypted with its own keys in a secure zone in the cloud."
