A Natural User Interface and Blockchain-Based In-Home Smart Health Monitoring System

In this paper, we propose a gesture-based secure interaction system with smart home IoT health devices to support elderly people or people with special needs. The framework uses a decentralized blockchain consensus for storing the smart home IoT health data and user identities. The framework leverages off-chain solution for storing raw multimedia IoT sensory payload and gesture data. Using our proposed health monitoring framework, a smart homeowner or service provider can create a cyber-physical space with a secure digital wallet for each human resident and authorized IoT health devices. Multiple authorized home residents can interact with the IoT-based smart home monitoring sensors, carry out user and IoT health sensory media registration, and transfer transactional values via secure tokens, as well as raw IoT health data payload through gesture. In this paper, we will present the design and implementation details of the smart home health monitoring framework in terms of gesture-based interaction with smart home IoT health devices, such as smart locks and light bulbs, which uses decentralized blockchain for security, trust, digital identity and privacy preservation.
