Abstract

The proposed work integrates a smart embedded health monitoring system with IoT. The data that are sensed and analyzed from the system are secured using blockchain technology and are transmitted and further analyzed. Blockchains are used in various sectors. Mainly they are welcomed for their secure transactions and the privacy that we can ensure through it. In this paper, our proposed system explored its uses in the healthcare sector. The health sector is where information is of privacy concern for patients and needed information for doctors treating them. Blockchain is the best-suited solution for Identity and Access Management (IAM) needed in the healthcare sector. As blockchains have different types named public and private blockchains, we recommend private blockchains be implemented where no anyone can make transactions and mine the transactions. Patients, doctors, and hospital organizations care for their privacy, and authorized access to others’ data, is the reason for the choice of the private blockchain. Adding to the IAM, blockchain also accounts for flexibility, decentralization, and an immutable ledger. Those operations are authenticated and authorized by a blockchain admin who has no relationship with the entities that exist in the network. The owner of the data is given the sole control of permitting access to their data. Our system asks patients for permission to be given to any doctor who is requesting access to those data. Also, patients can permit a doctor they want within the network. Hyperledger uses no online currencies and hence no miners to wait for. This is important as it reduces the waiting time for a transaction to be verified. REST API is used for collecting information requested from the blockchain and presenting it to the end-users. The proposed system is very unique to the date in which a dedicated smart embedded system is developed to monitor the vital parameters of the patient; once the abnormality is sensed, it will be spontaneously alerted and the connected recording system is activated after the sensors read the deviations very accurately and are unique than conventional methods. Our system provides a secure, reliable, and IAM-included network in a webpage that can be accessed across all devices.
