Wearable computing is technology worn on the body that interacts with digital systems, such as smart glasses, watches, rings, or health bands. These devices are designed for hands-free use, continuous sensing, and quick access to services. Because they stay close to the user and often contain cameras, microphones, GPS, or biometric sensors, they create a larger privacy and security surface than many traditional gadgets.
In cyber security, wearables matter because they can collect sensitive data about the wearer and nearby people, then share it through apps, cloud services, or paired phones. Defenders focus on secure pairing, strong authentication, narrow permissions, clear recording indicators, and minimal data retention. Attackers may target weak Bluetooth connections, poorly protected companion apps, or cloud accounts to steal data or hijack device functions. Wearable computing is therefore not just a hardware category; it is a security and privacy problem that depends on how sensing, storage, and sharing are controlled.
