Wearable gadgets are becoming an integral part of our daily lives, much like smartphones did a decade ago. These devices include smartwatches, smart glasses, hearables, fitness and health trackers, smart jewelry, and smart clothing. Their growing popularity stems from their convenience and multifunctionality—users can receive notifications, control media, use virtual assistants, track workouts, and check emails directly from their wearables.

Some well-known devices include the Apple Watch, Fitbit, Pebble Watch, Microsoft Band, Jawbone Up, Nike+ Sportband, and Motiv Ring. Medical wearables like iHealth’s wireless pulse oximeter and Withings' blood pressure monitor have also gained traction.

Wearable technology relies on microprocessors, sensors, and wireless communication protocols such as Bluetooth, Wi-Fi, and NFC. These devices typically connect to a smartphone, which acts as a base station for processing and transmitting collected data. Despite this, many users wrongly assume that coupling with a smartphone automatically ensures security—an assumption that leaves them vulnerable to cyber threats.
