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.
Keywords
