Decentralized Phr Application

Abstract

Patients face challenges such as a lack of trust in the healthcare system, difficulties in securely storing and accessing their data, as well as fragmentation of health records across multiple providers. This paper presents a detailed overview of the design of a decentralized Personal Health Record (PHR) application. Additionally, the paper includes a detailed description of creating B2C smart contracts using the Solidity programming language. Through a review of existing PHR applications based on blockchain, we introduce our innovative decentralized PHR application, highlighting its ability to effectively integrate patient data from various sources while preserving privacy and data security. Furthermore, we discuss the business model of our application and its contribution to enhancing the healthcare ecosystem, emphasizing the benefits it provides to both users and healthcare providers.
