Design And Implementation Of Medical Insurance System Based On Blockchain Smart Contract Technology

In recent years,with the continuous upgrading of block chain technology,block chain business scene is more and more.More and more practitioners begin to pay close attention to block chain technology,and actively build their own block chain project,even some industry experts predicted that block chain technology may bring about the second revolution of the Internet.For now,block chain technology with its decentralized,openness,self-contained,not tamper with the information,anonymity and other characteristics,application in the legal industry,power industry,the financial industry and so on.And in the medical insurance industry,insurance company and policy-holder disputes often occurs,the cause of the dispute may be policy-holder to provide false information insurance fraud,or insurance both sides in the process of claim for the cognizance of the disclaimer is different.With the digitalization of medical information,medical information data can be stored in a block chain,these data is reliable,cannot be tampered with,real-time synchronization.So with policy-holder and insurance company management will bring great benefits.Under the above background,in view of the field of medical treatment insurance,designed and implemented a set of medical insurance system based on intelligent block chain contracts.First,the thorough analysis of the block technique,a specific hash algorithm(SHA256 algorithm),encryption technology(mainly asymmetric encryption algorithm),distributed consensus mechanism,Merkle tree,and block chain,etc.By studying the etheric fang and intelligent contract technology involved,you can use to build private chain way to build your own block chain applications.Specific ways for private chain generates various nodes,will be deployed into the private intelligence contract chain,using block chain private chain of decentralization,data cannot be tampered with,and the characteristic of the information of traceability,make insurance as well as the storage of medical data more secure,insurance compensation is more reliable.Second,the intelligent medical insurance contracts.Specific for patients through the system to purchase the insurance contract,and can be real-time query their claims,medical institutions through the platform system to upload the patient's health information,or submit the patient's medical payment information,the insurance company through the platform to develop the patient's exclusive insurance contract,or give patients with medical claims.Finally,with intelligent contracts as the core,has developed a set of medical insurance system based on this,this system has a clear system of pay,bring a good user experience for the user,proved that the study of meaning and value.
