CES 2024: Will the Coolest New AI Gadgets Protect Your Privacy?

Phones and computers host some of the most private information about us — our financial information, photos, text histories, etc. Hardly any of it compares, though, with the kind of data that'd be gathered by your future, AI-integrated bathroom mirror.

Amid all of the other latest and greatest innovations at CES 2024 in Las Vegas this week, the Bmind Smart Mirror stands out. It combines natural language processing (NLP), generative AI, and computer vision to interpret your expressions, gestures, and speech. Marketed as a mental health product, it promises to reduce stress and even insomnia by providing you with words of encouragement, light therapy, guided meditations, and mood-boosting exercises.

All that, purportedly, plus the promise that your morning hair, blackheads, and most unflattering angles will be kept secure.

In today's world of consumer electronics, privacy and security are increasingly a selling point. But that may not be enough to counterbalance the troves of new data your AI-enabled car, robot, and now mirror have to collect about you to function properly, and all the bad actors (including some vendors themselves) who'd like to get their hands on it.

Even prior to the AI revolution, companies were facing challenges in building adequate data protections into their gadgets. Now it's even harder, and the dearth of relevant laws and regulations in the US means that there's little authorities can do to force the issue.

Handling Privacy in AI-Enabled Gadgets

"Stealing private data, we know, has been a threat to devices for a long time," says Sylvain Guilley, co-founder and CTO at Secure-IC. Data-heavy AI products are particularly attractive to bad actors, "and, of course, they house threats like [the potential to build] botnets with other AI devices, to turn them into a spying network."

Meanwhile, there are plenty of good reasons why consumer electronics manufacturers struggle with meeting modern standards for data protection (beyond all of the known, cynical reasons). There are resource constraints — many of these devices are built on "lighter" components than your average PC — that are accentuated by the demands of AI, and variation in what customers expect by way of protections.

"You have to be super careful about even enabling people to utilize AI," warns Nick Amundsen, head of product for Keeper Security, "because the model is, of course, trained on everything you're putting into it. That's not something people think about when they start using it."

To assuage its half-naked users' concerns, Baracoda explained in a promotional blog post on Jan. 6 that its smart mirror "gathers information without any invasive technology," and that its underlying operating system — aptly named "CareOS" — "is a privacy-by-design platform that stores health and personal data locally, and never shares it with any party without the user's explicit request and consent."

Dark Reading reached out to Baracoda for more detailed information about CareOS, but hasn't received a reply.

However, not all gadgets on display at this year's event are promising "privacy-by-design." The fact is they simply don't have to, as legal experts are quick to point out.

Few US Laws Apply to Privacy and Security in CE

In the US, there are privacy laws for health data (HIPAA); financial data (GLBA); and government data (the Privacy Act of 1974). But "there is no direct statute that regulates the general consumer Internet of Things (IoT) or AI," points out Charlotte Tschider, associate professor Loyola University Chicago School of Law, and author of multiple papers exploring what such guardrails might look like.

Instead, there's a patchwork of semi-related and state-level laws, as well as actions from regulators which, in the gestalt, might start to look like a guidebook for consumer devices.

Last July, for one thing, the White House announced a cybersecurity labeling program for smart devices. Though far from mandatory, its aim is to encourage manufacturers to build better security into their gadgets from the outset.

The IoT Cybersecurity Improvement Act of 2020, and Senate Bill 327 in California set a course for security in connected devices, and Illinois' Biometric Information Privacy Act (BIPA) takes direct aim at your average iPhone or smart mirror. And, perhaps most relevant of all is the Children's Online Privacy Protection Act (COPPA).

COPPA was designed to help parents control what information companies can gather about their children. "COPPA's a big one," Amundsen says. "Companies might not realize that they're entering into the scope of that law when they're releasing some of these products and some of these AI capabilities, but certainly they'll be held accountable to it."

The first IoT electronics company to learn that lesson was VTech, a Hong Kong-based consumer electronics manufacturer. For the crime of "collecting personal information from children without providing direct notice and obtaining their parent's consent, and failing to take reasonable steps to secure the data it collected" in its Kid Connect app, the Federal Trade Commission (FTC) ordered VTech to pay a fine of $650,000 in 2018.

The fine was a drop in the bucket for the $1.5 billion company, but it sent a message that this quarter-century-old law is America's most effective tool for regulating data privacy in modern consumer devices. Of course, it's only relevant for consumers under the age of 13, and it's far from flawless.

Where Consumer Electronics Law Needs to Improve

As Tschider points out, "COPPA doesn’t have any cybersecurity requirements to actually reinforce its privacy obligations. This issue is only magnified in contemporary AI-enabled IoT because compromising a large number of devices simultaneously only requires pwning the cloud or the AI model driving function of hundreds or thousands of devices. Many products don't have the kind of robust protections they actually need."

She adds, "Additionally, it relies primarily on a consent model. Because most consumers don't read privacy notices (and it would take well over a hundred days a year to read every privacy notice presented to you), this model is not really ideal."

For Tschider, a superior legal framework for consumer electronics might take bits of inspiration from HIPAA, or New York State's cybersecurity law for financial services. But really, one need only look across the water for an off-the-shelf model of how to do it right. 

For cybersecurity, the NIS 2 Directive out of the EU is broadly useful," Tschider says, adding that "there are many good takeaways both from the General Data Protection Regulation and the AI Act in the EU."

However, she laments, "they likely will not work as well for the US. The US legal system is in part based on freedom to contract and the ability of companies to negotiate the terms of their relationship directly with consumers. Regulations designed like the EU's laws place substantial restrictions on business operation, which would likely be heavily opposed by many lawmakers and could interfere with profit maximization."
