Internet of Things: A New Personal Information Pipeline

The home used to be the most private place in a person’s life. Today it contains microphones, cameras, motion sensors, location trackers and always-on network connections, most of which were added because they were convenient, discounted or came free with something else. Collectively these devices are called the Internet of Things, and they are a new pipeline for personal information. This guide explains what connected devices collect, where that data goes, what can go wrong, and how to enjoy smart technology with fewer privacy and security costs. It builds on our series about how smart homes are huge data mines.

1. What counts as an Internet of Things device

Almost anything that connects to your Wi-Fi or Bluetooth and communicates with a service qualifies:

Smart speakers and displays
Smart televisions and streaming sticks
Cameras, video doorbells and baby monitors
Thermostats, lighting, plugs and locks
Robot vacuums with mapping sensors
Fitness trackers, watches and health devices
Connected appliances
Vehicles with telematics
Children’s toys with microphones or cameras
RFID cards and tags (see RFID and smart cards)

Each device may have its own app, its own account and its own privacy policy. The result is a patchwork where no single settings screen controls everything.

2. What these devices collect

Device	Typical data
Smart speaker	Voice recordings, requests, device usage, linked accounts
Smart TV	Viewing habits, app usage, sometimes content recognition data
Camera or doorbell	Video, audio, motion events, visitors, schedules
Thermostat	Occupancy patterns, temperatures, schedule
Robot vacuum	Floor-plan maps, usage times
Wearable	Heart rate, sleep, steps, location, health indicators
Vehicle	Location, driving behavior, connected phone data

Individually these look mundane. Together they reveal when you wake, when you leave, who visits, what you watch and what your health looks like. Our article on whether your smart TV is gathering personal data describes one example in detail.

3. Where the data goes

Most IoT devices are designed to send data to the manufacturer’s cloud. From there it may flow to:

The manufacturer, for features, analytics and product improvement.
Service partners, for voice processing, storage or content recommendations.
Advertisers and data partners, depending on the company’s policy and your settings.
Law enforcement, through lawful requests.
Attackers, if the account or device is compromised.

Policies vary, so read them. The privacy implications are not abstract: in 2023 the Federal Trade Commission announced a settlement with Amazon over its Alexa voice assistant involving children’s voice recordings, with a $25 million civil penalty and requirements to delete certain data (ftc.gov). The case illustrates that retention and deletion practices matter.

4. The security side of the pipeline

Weak defaults

Many devices ship with default passwords or easily guessed settings. Attackers scan the internet for them.

Missing updates

Cheap devices may never receive security updates, and even good ones need you to install them.

Insecure apps and accounts

A device is only as secure as the account that controls it. A reused password and no two-factor authentication make a camera feed available to anyone who guesses it.

Network exposure

A compromised smart plug can become a foothold into your home network, with access to computers and phones.

Resale and disposal

Devices sold or thrown away without a factory reset may leave data and account links behind.

These risks matter more as device counts grow. A household with a dozen connected devices has a dozen potential doors.

5. How to lock down your connected home

Take inventory

List every connected device in your home. Check your router’s connected-device list for ones you forgot. You cannot secure what you do not know exists.

Change default credentials

Replace default usernames and passwords with unique ones in a password manager. Turn on two-factor authentication for device accounts.

Update firmware

Enable automatic updates when available. Retire devices that no longer receive security fixes.

Segment your network

Put smart devices on a guest or separate network, away from computers and phones that hold sensitive data.

Disable what you do not use

Turn off microphones, cameras, remote access and voice purchasing if you do not need them. Mute smart speakers when you have private conversations.

Review privacy settings

Opt out of data sharing and ad personalization where offered. Delete voice and video history regularly. Our guide on privacy settings on your devices can help.

Buy carefully

Prefer vendors with clear privacy policies, regular updates and the ability to work offline. Avoid unknown brands with unclear support.

Reset before you sell or recycle

Perform a factory reset and remove the device from your account.

6. Special cases

Children

Connected toys and monitors may record audio or video. Read policies, disable features that are not needed and avoid devices that require unnecessary personal information.

Rental homes and shared spaces

Check for cameras and unknown devices in short-term rentals. Disclose cameras you own.

Health and wearables

Health data is sensitive. In the United States, many consumer wearables are not covered by HIPAA the way a medical provider’s records are. The HHS HIPAA guidance explains which entities are covered. Treat wearable data as sensitive regardless.

Vehicles

Connected cars may collect location and driving behavior. Review account permissions and opt out of data sharing where possible.

7. From devices to dossiers

Why does this matter beyond a single device? Because IoT data can be combined with other records. A broker may already know your address, age and household. Add device-derived inferences about schedules and habits, and the profile becomes more valuable and more intrusive. Public records that show your home address make the picture even more precise. Reducing broker listings therefore reduces the power of any device data that leaks. See everything you need to know about data brokers and our guide to removing yourself from people-search sites.

8. Timeline: securing a smart home

When	Action
Day 1	Inventory devices, change default passwords
Week 1	Update firmware, enable two-factor authentication
Week 2	Segment network, disable unused sensors
Month 1	Review privacy settings, delete histories
Quarterly	Check for updates, retire unsupported devices

9. A room-by-room look at the connected home

In the living room, a television reports viewing habits and a speaker listens for its wake word. In the kitchen, a connected appliance may share usage data and a display may sit on a counter with a microphone. In the hallway, a doorbell camera records visitors and schedules. In the bedroom, a wearable tracks sleep and a smart plug controls a lamp. In the garage, a connected opener and a vehicle app log arrivals and departures. Each room has its own devices, its own app and its own policy, and none of them was designed with the whole picture in mind.

Walking through your home in this way is the quickest route to an honest inventory. For each device ask three questions: does it need the internet to do its job, does it need a microphone or camera, and does the company need to keep what it collects? If the answer to all three is no, switch the feature off.

10. Questions to ask before buying

Before you buy any connected product, check how long the manufacturer promises security updates, whether the device works without an account, where data is stored and whether you can delete it. Look for clear opt-outs for advertising and data sharing. Search for the product’s history of vulnerabilities. A cheaper device that never receives patches often costs more in the long run. The Consumer Financial Protection Bureau and the FTC both publish general guidance on protecting yourself when new technology collects data.

11. Reducing the profile that devices feed

Even careful configuration cannot make a smart home invisible. What you can do is limit how well anyone can connect device data to your name and address. Remove listings from people-search sites, use separate accounts for different ecosystems and avoid linking devices to social profiles. Our look at how smartphones constantly send personal information shows the same logic applies to phones, which sit at the center of most smart homes.

12. Three scenarios and what to do

Scenario 1: You find an unfamiliar device on your network. Identify it, change your Wi-Fi password and review router settings.

Scenario 2: A camera feed shows unusual access logs. Change the password, enable two-factor authentication and update firmware.

Scenario 3: You are giving away an old speaker. Delete recordings, factory reset and remove it from your account.

13. Myths and facts

Myth	Fact
Smart devices only matter if I am a target	Automated scanners attack the weakest devices
Brand names do not ensure safety	Update support matters more than logos
Turning off an app turns off collection	Device-level settings may still collect
Voice assistants record nothing until needed	Wake-word detection involves some capture and storage
IoT data is anonymous	It is tied to accounts, addresses and households

14. Common mistakes

Leaving default passwords.
Never updating firmware.
Placing every device on the main network.
Ignoring privacy settings during setup.
Forgetting to wipe devices before disposal.
Treating device data as harmless.

15. Questions to ask yourself

Which devices in my home have microphones or cameras? Which have not been updated in a year? Which accounts use reused passwords? What does each device give me that I would miss? Remove or restrict the ones that fail the test.

18. Frequently Asked Questions

What is the Internet of Things?

It is the network of everyday devices that connect to the internet, such as speakers, TVs, cameras, thermostats, appliances, vehicles and wearables, and exchange data with services and each other.

What data do smart devices collect?

Voice recordings, video, usage patterns, location, device identifiers, schedules and sometimes health data, depending on the device and settings.

Are smart devices a security risk?

They can be. Weak default passwords, outdated firmware and poor vendor support make some devices easy targets, and a compromised device can expose your home network.

Should I put smart devices on a separate network?

Yes, if your router supports a guest or IoT network. It limits what a compromised device can reach.

Do smart speakers listen all the time?

They listen for a wake word, and some recordings are stored. Review settings, delete history and mute microphones when not needed.

Can IoT data be sold?

Policies differ. Some data may be shared with partners or used for advertising, and data brokers can combine inferred information with other records, so read privacy settings and opt out where possible.
