Using Blockchain to Achieve Decentralized Privacy in IoT Healthcare

With the advent of Internet Things (IoT), e-health has become one main topics research. Due to sensitivity patient information, privacy seems challenging. Nowadays, data is usually stored in cloud healthcare programs, making it difficult for users have enough control over their data. The recent increment announced cases security and surveillance breaches compromising patients' call into question conventional model, which third-parties gather immense amounts Healthcare In this work, we try resolve issues mentioned above by using blockchain technology. We propose a blockchain-based protocol suitable applications that does not require trust third party provides an efficient privacy-preserving access mechanism. Transactions our proposed system, unlike Bitcoin, are entirely financial, do use methods consensus operations like Proof Work (PoW). It IoT because devices resources-constraints. Usage appropriate method helps us increase network efficiency, as well reducing cost, i.e., bandwidth processor usage. Finally, provide analysis protocol.
