Implementatons of Health-Promotion IoT Devices for Secure Physiological Information Protection

The research implemented a set of health-promoting devices. One of the Internet-of-Things (IoT) devices is a wearable bracelet that can measure the user’s blood oxygen value of foots in real time. When abnormal values are detected, the bracelet can immediately notify the user through LINE messages, and simultaneously automatically power on another device of a foot-spa machine to preheat the water in it. Consequently, the hypoxic user can use the foot-spa machine to relieve blood hypoxia condition. Furthermore, when it is detected that the user not using the foot-spa machine, other warning messages will issue to the family members in the same LINE group, and then automatically turn-off the foot-spa machine to save power. Especially, in order to ensure personal physiological information is protected transmitting through the network, the implementation perform special encryption processing to save the computational burden of the microprocessor or to reduce the transmission latency over the network. Performance benefits for the encryption adaptions of the implemented platform are provided and discussed in the section of experimental results.
