Study on Blockchain-Based Healthcare Insurance Claim System

Healthcare insurance is a vital part of today's world. With the increase in the number of health issues, not everyone can afford all kinds of treatment required and the time wasted in claims. The introduction of blockchain technology is proving to be of great benefit to lower and middle-class people. Different types of blockchain are being used to provide maximum benefits to society. Permissioned and advanced blockchain provides security and transparency to sensitive information. The attribute-based signature (MA-ABS) scheme with multiple authorities is used to provide privacy to patient's data. Smart Contracts for Ethereum Blockchain are being used to automate the process of insurance claims and payments to patients. Hyperledger Fabric is used for the implementation so that RESTful APIs can be used for easy access of data on the blockchain. The healthcare insurance system implementation on blockchain will eliminate the intermediaries, causing delay, fraud, high cost, etc., and bring about a faster process of claims and treatment while maintaining the security and privacy of all medical records such as EHRs and EMRs.
