A Blockchain based medical records management system that has been implemented on Ethereum platform

Medic@Chain

A blockchain-based Medical Records Management System

Today, doctors & health professionals are limited in the level of care they can provide because due to inability to view your complete, accurate health records. The proposed solution is a blockchain network created by the Health Department, who registers the doctors in this network. The doctors can publish patients medical records safely on blockchain network.

System Requirements

1. Operating System : Ubuntu 16.04
2. System RAM : 4GB or Above

Step by step instructions for installing / setting up the application for use

Step 1: Download the repostory using the command:

 Git Clone "https://gitlab.com/ced_b3_projects/ced-b3-g10.git"

Step 2: Install the dependecies using the command:

 npm Install  

Step 3: Use the following command to compile smart contract:

 truffle compile  

Step 4: Use one of the following commands to connect to the devchain,private or public chain:

Devchain:

1: Run the chain using following command

geth --datadir dev --networkid "4002" --rpc --rpcport 8545 --ipcpath "~/.ethereum/geth.ipc" --rpccorsdomain "*" --rpcapi "db,personal, eth, web3, net" --dev

2: In new terminal find coin base address and Copy to app.js

geth attach
> eth.accounts

3: Copy coin base address to app.js.Create 4 more accounts and pass ether to them using following comments

personal.newAccount("")//4 times
eth.sendTransaction({from:eth.accounts[0],to:eth.accounts[1],value:100000000000000000000})//pass 100 ether to each account

4: Cut the chain and rerun the chain using following comment to unlock the new accounts

geth --datadir dev --networkid "4002" --rpc --rpcport 8545 --ipcpath "~/.ethereum/geth.ipc" --rpccorsdomain "*" --rpcapi "db,personal, eth, web3, net" --dev --unlock 1,2,3,4 --allow-insecure-unlock

Password: Enter Key

Private chain:

cd geth

geth --identity "miner" --networkid 4002 --datadir data --nodiscover --mine --rpc --rpcport "8545" --port "8191" --unlock 0,1,2,3 --password password.txt --ipcpath "~/.ethereum/geth.ipc" --rpccorsdomain "*" --rpcapi "db,eth,net,web3,personal" --allow-insecure-unlock 

start mining using the following command in new terminal, before doing any transaction:

  geth attach 

  miner.start()  

Password: Enter Key

Ropsten:

1: Run the chain using following command

 geth --testnet --syncmode "light" --datadir "rop" --rpc --rpcapi "db,eth,net,web3,personal" --rpcport "8545"  --rpccorsdomain "*" --allow-insecure-unlock

2: use java script console and connect to running chain.

    geth attach http://127.0.0.1:8545

3: Wait for the node to synch fully (will take some time). use the below command to know the status

    eth.syncing

false - incase no synching happening (same for synching finished also), otherwise will show the status

4: Create a new account using the following command

    personal.newAccount("")

 The password is an enter

create 3 more accounts

3: Transfer ether to each account using metamask account

4:Cut and ReRun the chain using following command

geth --testnet --syncmode "light" --datadir "rop" --rpc --rpcapi "db,eth,net,web3,personal" --rpcport "8545"  --rpccorsdomain "*" -unlock 0,1,2,3 --allow-insecure-unlock

Step 5: Use the following command to deploy the smart contract to the connected chain:

 truffle migrate  

Step 6: Run the dapp using the command

 npm start  

Execution Flow:

Step 7: Login as admin to register the doctors. Admin has the privilege to register or delist the doctors.

Step 8: Only registered doctors can add health records of patients. The patient registration will be done at this point of time.

Step 9: Only registered patients can access the patient login portal. The registered patients can view their health records history. Also the patients can view the health records w.r.t respective doctors.

Step 10: Only patients has the privilege to grant access to doctor, so that the doctor can view the respective patients health records for a particular period. The patients can revoke the access given to doctor at any point of time.

Step 11: Registered doctors can view patient health records only when access to doctor is given by patient.
