IPFS-based Blockchain Enabled System for Secure Data Storage and Access in Healthcare

Abstract

Healthcare is among the industries that are very interested in blockchain technology due to its potential. Blockchain and the interplanetary file system are emerging technologies that include distributed fault tolerance, decentralization, flexible security features, and effective data management. By providing a decentralized solution, the blockchain and Interplanetary file system integration addresses the issues of data security, integrity, and accessibility in healthcare systems. The healthcare industry electronically maintains medical data, including prescriptions, diagnostic results, and personal patient information. When there is a risk of a data breach or loss, many healthcare institutions store patient data utilizing centralized models and third-party applications. The current centralized system has a 75% accuracy rate. To guarantee the integrity and security of medical data, the suggested system would demonstrate the qualities of blockchain technology, including immutability, transparency, and decentralization. The suggested system's methodology stores and hashes data using Ethereum smart contracts and consensus mechanisms. Approaches based on consensus algorithms are used to combine data upload and storage authentication and validation. Following data mining, the uploaded data will be verified and saved in the Interplanetary File System with unique content identifiers. Only those who have registered are able to access the saved data. The risk of unwanted tampering or data breaches is decreased because all transactions pertaining to the storage and access of data are recorded in an unchangeable and transparent manner. The suggested distributed and decentralized system has a 90% accuracy rate. Moreover, the decentralized nature of blockchain eliminates the necessity for a central authority, so reducing the likelihood of a single point of failure and enhancing data resilience.
