What are smart rings?
If you know what a smartwatch (like Apple Watch) does, then a smart ring does most of the same but in an even smaller package.
Smart rings are equipped with sensors that can measure heart rate, blood oxygen levels, and even stress. Similar to other wearable devices like fitness trackers and smart jewelry, smart rings need to be paired with an app so its users can track their progress, set goals, and even share their health stats with friends.
Smart rings can also be used to control other devices. For example, you can use gestures or voice commands to control your smart home devices through your smart ring, such as turning off the lights or adjusting the thermostat. Some smart rings also include haptic feedback, which can alert you to incoming calls or messages, so you never miss an important notification.
With the use of sensors and machine learning, these nifty devices are getting more sophisticated and accurate in tracking biometric data. However, as the ring’s processor (i.e., its core computer) gets smarter, users should stay wary of privacy and security risks.

Security and privacy challenges facing smart rings
While the idea of having all of your personal information at your fingertips (literally) may seem appealing, it could come with a few risks.
Data breaches
From your location to your heart rate and bank account details, smart rings collect a lot of personal data—and all this data is stored on servers owned by the company that made the ring. This means that if the organization’s servers were to get hacked, all that personal information could fall into the hands of cybercriminals. While companies may have strong security measures in place to protect user data, there is always some degree of risk.
Shared user data
Another risk to privacy with tech wearable rings is the potential for companies to share or sell user data. This could lead to targeted advertising—or worse, like discrimination by medical insurers based on health data.
Lack of authentication
Most smart rings have no way of authenticating or verifying that the person accessing or using them is who they claim they are. This makes them susceptible to DoS attacks and battery drain hacks, where an attacker may try to disrupt the normal functioning of the ring by overloading it with excessive requests.
Limited encryption
Some wearable tech devices are known to send and receive data to or from an app in plain text, which means it’s unencrypted and therefore unsecured. It’s possible that certain smart rings do this, too. This makes the smart ring data vulnerable to interception and theft.

Physical tracking
Because they’re worn on your body, tech wearable rings can also pose a risk to personal privacy in the physical world. For example, if a ring is equipped with a GPS, it can be tracked by utilizing the data transmitted by the GPS receiver. This data, which includes the ring’s location and movement, can be captured by a third-party device and used to create a record of the user’s location over time—subsequently, opening the door to stalking.
Surveillance
If the device maker shares data with governments or other organizations, smart rings could also be used by them to track a person’s movements and monitor their activities.
