Abstract: Health-Ledger model (HLM) is proposed to complete personal health history based on blockchain technologies and IoT devices. In HLM, all users' physiological signals and medical records are measured and recorded through IoT devices. Blockchain technologies are adopted into HLM; each health record is transferred into a meaningless content composed of serial number and alphabets in order to protect user's privacy. All records are uploaded into personal health blockchain automatically and stored permanently. Owing to decentralised data storage, users have privilege to access their personal blockchain for checking their own health records arbitrarily. HLM is built based on the functions of automatic data collection and alarm system which are achieved by IoT devices in a well wireless network environment, and the blockchain technologies of encryption, hash, peer-to-peer storage forming a personal health blockchain.

Keywords: blockchain; internet of things; IoT; secure mechanism; decentralised; health ledger; peer-to-peer; P2P; cryptography; hash algorithm; permanent data storage; digital certification.
