Protection of Clinical Records using Blockchain with Proof of Stake as Consensus Algorithm

Abstract

The security of a patient’s clinical records and their confidentiality is a crucial responsibility for any medical orga- nization seeking to operate optimally and protect the privacy of its patients. The loss of a patient’s clinical record in a data breach can have disastrous consequences. According to the 2022 Data Breaches Investigations Report by Verizon, human error contributed to 82% of data breaches. To address this issue, this research paper proposes a system that integrates user- side inspection software and blockchain technology to prevent data breaches by leveraging blockchain’s transparency and immutability. Our proposed system can prevent data breaches by protecting sensitive files from unauthorized access within the organization as well as outside the organization while also ensuring the secure transmission of cryptographically-secured files. The system utilizes a Proof of Stake (PoS) consensus algorithm to enhance security, scalability, and efficiency so that it can even be used by organizations without considerable computer architecture.
