The Internet of Things (IoT) has changed the way we gather medical data in real time. But, it also brings worries about keeping this data safe and private. Ensuring a secure system for IoT is crucial. At the same time, a new technology is emerging that can help the IoT industry a lot. It s called Blockchain technology. It keeps data secure, transparent, and unchangeable. It s like a ledger for tracking lots of connected devices and making them work together. To make IoT even safer, we can use facial recognition with Convolutional Neural Networks (CNN). This paper introduces a healthcare system that combines Blockchain and artificial intelligence in IoT. An implementation of Raspberry Pi E-Health system is presented and evaluated in terms of function s cost. Our system present low cost functions.
