DESIGN A SECURE AUTHENTICATION PROTOCOL FOR BLOCKCHAIN BASED SHARING OF ELECTRONIC HEALTH RECORDS
Etikala Aruna, Dr. Arun Sahayadhas
Abstract
The Internet has become increasingly important to our daily lives during the past decade. Modern communication technology has improved the efficiency of online services including e-banking, e-rail, and e-health. Not only the Electronic Health Record (EHR) possess immense value, but also implies a lot of privacy. One important strategy for raising the standard of medical care and lowering costs is the sharing of health data. The only way to maintain the privacy of health information is to keep it encrypted, but this compromises search usefulness and flexibility. This paper presents a Secure Authentication Protocol for BlockChain Based Sharing of Electronic Health Records. The described method provides two key advantages with the use of blockchain technology. It is truly decentralized and independent from a single point of failure since it was first free from a reliable authority. Second, as a result of the workload being split among the blockchain network's consensus nodes, it is also computationally efficient. A constant key generation execution time and a linearly increasing file size-dependent encryption time were both obtained by the described approach.
