IoT Devices and Data Privacy – Hidden Legal Challenges for Businesses
The “Internet of Things” (IoT) has grown far beyond simple home gadgets like smart speakers. Today, businesses across all sectors use smart building sensors, connected medical tools, industrial monitors, and employee wearables.
While these devices make operations faster and more efficient, they also collect a massive amount of personal data. Many companies underestimate the legal duties that come with these devices. Then one day, a security breach or a government investigation makes the risks visible.
Why The Rapid Growth Of IoT Devices Creates Major Data Risks
The amount of data created by IoT devices is staggering. In 2023, there were roughly 16.7 billion connected devices worldwide, and that number is expected to pass 27 billion by 2025.
Every one of these devices is a data endpoint that can create legal trouble if the information it gathers is not managed correctly. The challenge is that these devices often collect info continuously and invisibly. Most people do not even expect it.
What Types Of Data Do IoT Devices Collect In Business Environments
In a business setting, most of this information is classified as sensitive personal information (SPI) under modern state laws.
Location And Biometric Data
IoT tools often collect precise GPS locations through fleet trackers or logistics monitors. They also frequently capture biometric data, such as faceprints or fingerprints, for building access and secure room entry.
Under laws like California’s CPRA, these data points require much higher levels of protection than a standard name or email address.
Audio And Health Information
Connected devices may track health data through employee wellness watches. They may also record audio through voice-activated systems in boardrooms. Because this collection is often “always-on,” it captures sensitive and private conversations or physical conditions.
Why IoT Devices Make Privacy Notice And Consent More Difficult
Standard privacy laws rely on a notice and consent model:
- You tell people what you are collecting.
- They click a button to agree.
IoT devices break this model because they usually do not have screens. A smart thermostat or a motion sensor does not present a terms of service agreement.
This collection is ambient and invisible. There is a lot of legal uncertainty about whether current privacy notices actually satisfy the law. The FTC has warned that businesses must find meaningful ways to give users a choice.
How State Privacy Laws Apply To Data Collected By IoT Devices
Several state laws now specifically target data collected by these devices. The Illinois BIPA law is a major risk for any company using fingerprint or facial recognition. Failing to get written consent can lead to massive lawsuits.
California has two major rules:
- the CCPA/CPRA, which protects GPS and biometric data,
- and SB-327, which was the first law in the U.S. to require that all connected devices have “reasonable” security features.
Other states like Virginia and Colorado have passed similar rules regarding sensitive data.
Why IoT Security Weaknesses Can Create Legal Liability
IoT devices are often the weakest link in a computer network. Many come with default passwords that are never changed, or they lack the ability to use strong encryption.
According to a 2023 report from Palo Alto Networks, 57% of IoT devices are vulnerable to medium or high-severity attacks. If a hacker enters your network through a smart lightbulb and steals customer data, your company is still legally responsible for the breach. You may face government fines and be required to notify every victim within 30 to 60 days.
IoT devices create privacy risks that many businesses have not mapped out yet. If your organization uses connected devices in the workplace, consulting with a legal or cybersecurity professional can help you!
