NHDM Blockchain Application - README

Problem Statement

Compared with traditional paper-based medical records, electronic health records (EHRs) are widely used because of their efficiency, security, and reducing data redundancy. However, interoperability of data and privacy are two big challenges. The Government of India has attempted to create NHDM (National Health Data Management) to define interoperability.

A distributed ledger protocol composed of encrypted blocks of data organized in chains, blockchain represents a potential tool to solve the shortcomings of EHRs in terms of interoperability and privacy.

GRiD Blockchain Application

As participants of the GRiD (Government's Research in Distributed Ledger) initiative, you are expected to build an application that allows users to:

Set up a Blockchain Infrastructure

Identity Management
Medical Records Management

User Interface for Various Stakeholders

Clinic
Hospital
Individual Doctors
Diagnostics
Patient

Integration of Blockchain Infrastructure with Health Stack

The application should seamlessly integrate with the existing Health Stack system to ensure efficient data flow and interoperability.

Leverage Abha ID and Aadhar for Identity Management

Utilize Abha ID and Aadhar systems for robust and secure identity management across stakeholders.

Quick Search and Identification of Relevant Documents

The application should allow users to search for medical documents based on various parameters, including:

Date
Doctor
Document Type
Hospital Name
Patient Name

Secure Document Sharing in Different Formats

Users should be able to securely share medical documents in different formats, such as:

Image
PDF

Digitization of Personal Health Records (PHRs)

Facilitate the digitization of personal health records, eliminating the need for physical paperwork and enhancing data accessibility and portability.

How to Use the Application

To use the NHDM Blockchain Application, follow these steps:

Set up a user account and log in securely using Abha ID and Aadhar authentication.
Select your role among Clinic, Hospital, Individual Doctor, Diagnostics, or Patient.
Navigate the user-friendly interface to manage medical records, access patient data, and upload documents.
Utilize the quick search feature to find relevant medical documents based on various parameters.
Share medical records securely with other authorized stakeholders, enhancing collaboration and patient care.
Experience the seamless integration of the blockchain infrastructure with the existing Health Stack system, ensuring data interoperability.

Technologies Used

The NHDM Blockchain Application utilizes the following technologies:

Blockchain Protocol for secure and tamper-proof data management.
Abha ID and Aadhar for robust identity management and authentication.
User-Friendly Interfaces for easy navigation and adoption by stakeholders.
Data Encryption for enhanced data privacy and security.
