Security in wearable devices

Updated: Jul 11, 2023

Wearable devices have revolutionized the way we interact with technology, allowing it to seamlessly integrate into our modern lifestyles, offering a wide range of features and functionality in a compact, portable form factor. However, as we become more dependent on these technologies, it is essential to consider the security of wearable devices.


What are those devices?


Wearable devices are electronic devices designed to be worn on the body, incorporated into clothing or accessories. They provide specific functionalities, in addition to monitoring and collecting data about the user. These devices are usually connected to smartphones, tablets or computers, with free communication and data transmission.

Device Types


Wearable devices can have a variety of forms and functions. Some common examples include:

  • Smartwatches: Smartwatches that go beyond just telling the time. They may offer features such as message notifications, heart rate monitoring, fitness tracking, and integration with smartphone apps.

  • Fitness trackers: Small devices worn on the wrist or elsewhere on the body that track physical activity and health. They usually track data such as steps, distance traveled, calories burned and sleep quality.

  • Smart Glasses: Glasses that display digital information such as messages, maps and notifications directly in the wearer's field of vision. They are used for augmented reality, navigation assistance and other applications.

  • Health monitoring devices: These include sensors that monitor physiological parameters such as heart rate, blood pressure, blood oxygen levels and sleep quality. They help users keep track of their health and make useful data available to medical professionals.

  • Virtual reality devices: These are devices that provide an immersive experience in virtual environments. They can be helmets or glasses that track the movement of the user's head and display 3D images to create a feeling of being in a virtual environment.

Wearable devices have become more popular due to their convenience and diverse uses. They enhance productivity, health, fitness and the overall user experience by providing quick access to real-time personal information and data.


The importance of security in wearable devices


Security on wearable devices is of utmost importance due to the increasing popularity and use of these devices in our daily lives. A wide variety of personal data is collected, such as health information, location, activity patterns and even biometric data.

The following are some of the reasons why security on wearable devices is crucial:

  1. Physical threats: Because they are directly attached to the user's body, may be more vulnerable to physical threats such as theft or loss. Security includes features such as remote locking or data encryption to prevent unauthorized access to data stored on devices in case of existing threats.

  2. Wireless Connections: Nearly all wearable devices are connected to other devices, such as smartphones, through wireless connections such as Bluetooth or Wi-Fi. These connections may be vulnerable to cyberattacks such as data interception or spoofing. Ensuring the security of these connections is critical to protecting data transmitted between devices.

  3. Personal data protection: Wearable devices collect and store a large amount of personal data, including medical information, sleep habits, location and much more. Proper security is essential to ensure that this data is preserved from unauthorized access or misuse.

  4. Risks of Hacking and Data Theft: Like other Internet-connected devices, wearable devices are susceptible to cyberattacks. Hackers exploit vulnerabilities in devices with the intention of stealing data belonging to users, performing espionage or even taking control of devices. Effective security is critical to preventing these attacks.

  5. Health and Safety: Some wearable devices, such as heart rate monitors or medical devices, have an immediate impact on the health and safety of the user. If these devices are not secure, they can provide incorrect information or even cause physical harm to the user. It is essential that manufacturers ensure the safety of these devices to protect the health and safety of users.

Security on wearable devices is essential to protect users' privacy, the data they hold and also their health information. It is the responsibility of manufacturers and developers to implement security measures on devices so that they offer reliability and protection against the actions of cybercriminals. Users, in turn, must be aware of the risks associated with wearable devices and put in place the means that will protect them, if necessary..


How to minimize the risks


Below we have some points that users should have criteria that bring more security and minimize risks. see below:

  1. Keep your device up to date: Always install software updates provided by the wearable device manufacturer. These updates include important security fixes that protect against known vulnerabilities.

  2. Use strong passwords: Set up strong, unique passwords for the device and any related apps. Obvious passwords such as dates of birth or simple number sequences should be avoided. Therefore, it is recommended to use long passwords, which have combinations of uppercase and lowercase letters, numbers and special characters.

  3. Be aware of privacy settings: Check the privacy settings of the wearable and associated apps. Some devices may collect private data and still track location, so make sure your settings align with your privacy preferences.

  4. Enable two-factor authentication (2FA): If the wearable device or associated apps support two-factor authentication, enable this function. 2FA adds an extra layer of security by requiring a second form of authentication, such as a code sent via text message or an authentication app.

  5. Protect the physical device: In addition to online forms of security, remember to physically protect the wearable device. Keep it safe on your wrist or stored in a safe place when not in use.

  6. Manage App Permissions: Analyze which permissions are requested by the apps associated with the wearable device and grant only the necessary ones. Some apps ask for access to personal data or device functions that are not essential for their operation.

  7. Be careful when downloading apps: When installing new apps on the wearable device, make sure you only do so from trusted sources such as official app stores. Read the reviews and carefully review the required permissions before downloading.

  8. Use encryption: If the wearable device supports it, enable encryption of data stored on the device. It will help ensure that personal information is protected in the event that your device is lost or stolen.

  9. Monitor your activity and notifications: Pay attention to any unusual activity on your wearable device, such as suspicious notifications or unauthorized access. Report any issues to the device manufacturer or service provider.

  10. Connect to secure Wi-Fi networks: When connecting your wearable device to Wi-Fi networks, do not use public or unsecured networks. Prefer well-known, password-protected networks, such as your home network or trusted business networks.

These are the ways that will ensure the security of wearable devices. However, it's important to remember that security is an ongoing effort and being constantly up-to-date on security best practices is critical. Security on wearable devices is of utmost importance in preserving users' privacy and confidential data.
