Contactless Authentication for Wearable Devices Using RFID

Technological advancements are strongly integrated into our daily lives and an increasing trend prompts the usage of smart healthcare devices for health management. Health providers are beginning to use wearable devices as equipment that can support remote care services. As a result, an accurate, robust, lightweight, and convenient authentication system for smart healthcare devices is urgently required. Considering RFID technology, we present a contactless authentication mechanism that secures a smartwatch at the hardware level. When the authorized person uses the smartwatch, then power is "ON" otherwise "OFF". Thanks to our method the answer to the question "Am I authorized to use the wearable medical sensor?" and "Am I really the person who is proceeding?" is directly enforced by the system. This study significantly improved the usability and security of the authentication process.
