Introduction

This is a PHR storage and sharing system prototype that uses Blockchain, Searchable Symmetric Encryption and IPFS.

Steps to run locally (Linux)

There are six components in this system listed as follows:

1. Blockchain Node
2. IPFS Node
3. Key Distribution Server
4. Doctor Device
5. Hospital Server
6. Client Device

To run the system locally on a linux system follow the steps given below:

1. Install docker on your system, if not already installed.
2. Copy the configuration files from sample-configs directories to the root of their respective component directories.

Running Key distribution server

1. Run the key distribution server using python3 server.py.
2. By default, it will run on localhost:9005.

Running blockchain nodes

1. Replace address->kds->ip with the IP of your system in the config.yml file of the blockchain node component.
2. Run the blockchain nodes using init.sh command and supply the required parameters.
3. The gateway IP should be the IP of your system.
4. Give host-id as 0 and give the number of nodes as per your requirements (should be >= 4).

Running IPFS nodes

1. Run the IPFS nodes using init.sh command in the component directory and supply the required parameters by following the same rules as in the case of blockchain nodes.
2. Also specify the --bootstrap option.

Running Doctor Device

1. Run doctor device using python3 server.py.
2. By default, it will run on localhost:9001.

Running Hospital Server

1. Run hospital server by using python3 server.py
2. By default, it will run on localhost:9000.

Running Client Device

1. Run client device using python3 main.py.
2. You will receive a prompt through which you can interact with the system.
