Privacy-preserving healthcare data management system using blockchain technology

Abstract

In recent years, blockchain technology has gotten plenty of attention, with rising interest in an exceedingly type of way resembling as-Banking, Telecommunication, IoT, aid etc. Each different sector, Blockchain has additionally completed a massive task in medical aid specialties. Antecedently the standard EHR- based mostly systems were aggravated by several knowledge loss hazards, security and unchangeableness accord for the aid records, there was a niche between communications among varied brought about hospitals and what is more the reclamation of the data was thus uncomfortable. Blockchain has lessened these issues. Varied beginning points for Blockchain technology within the aid trade area unit the main target of this report. A redistributed info that is ever delayed thus far presents several benefits to the aid industry. These benefits get particularly overwhelming, once many alternative parties want access to identical data. Through a shared network infrastructure, totally different aid specialists will enter identical data. This can additionally allow the event of a brand-new category of Blockchain- grounded exercises in aid that may loosen wasted coffers and break vital useful issues with extra secured infrastructure. Either with the assistance of good contracts it’s going to be potential to alter a time- overwhelming method properly. This text describes a patient- doctor-centric construct for a redistributed aid management system that has a blockchain- based mostly on EHR and good contracts written in JavaScript. An acting epitome supported Hyperledger cloth and melodist technology has additionally been developed, guaranteeing the planned model’s security. Cyber criminals have been increasingly interested in healthcare data. Decentralization could help to lessen the annihilating effects of healthcare data. A peer-to-peer (P2P) network allows for decentralization, allowing multiple parties to store and conduct computation while keeping sensitive health data private. Blockchain technology is based on a decentralized or distributed method, which assures that its use is transparent and trustworthy. This study describes a patient-centric healthcare data management system that employs Blockchain as a storage medium to ensure anonymity. The use of cryptographic methods to safeguard patient data ensures pseudonymity. Healthcare providers are increasingly using Internet of Things (IoT)-based wearable technologies to speed up diagnosis and treatment. Hundreds of billions of sensors, devices, and vehicles have been connected to the Internet in recent years. Remote patient monitoring is one such technology that is now widely used in the treatment and care of patients. These technologies, on the other hand, pose serious privacy and security problems when it comes to data transfer and logging. These medical data security and privacy issues could cause a delay in treatment, possibly putting the patient’s life in jeopardy. We propose using a blockchain to manage and analyze healthcare large data in a secure manner. Blockchains, on the other hand, are computationally expensive, necessitate high bandwidth, and require additional computational capacity, making them unsuitable for most resource-constrained IoT devices aimed for smart cities. In this paper, we attempt to address the aforementioned concerns with blockchain and IoT devices. We offer a new framework of modified blockchain models that are ideal for IoT devices and rely on the network’s distributed nature as well as other privacy and security features. Our model’s added privacy and security features are based on advanced cryptographic primitives.
