Development of a Blockchain-Based Decentralized Authentication Prototype Integrated with SQL Server

2.-BULLET POINT VERSION (If it asks for key points)

You can paste this in the bullet/summary section:

Academic research prototype (not a full hospital system)

Decentralized authentication using blockchain (smart contract)

Integration with Microsoft SQL Server

Medical records stored in SQL Server (not on blockchain)

Blockchain used for authentication hash validation

Architecture documentation required

Basic performance observation (authentication response time)

Conceptual alignment with GDPR and HIPAA (no legal certification required)

Full source code and technical explanation required

3.-FULL DESCRIPTION (Complete Version to Post)

Hello,

I am working on an academic research project and I need a developer to design and implement a prototype of a decentralized authentication system based on blockchain technology, integrated with Microsoft SQL Server.

Important: This is strictly an academic prototype. I do NOT need a complete hospital management system.

Project Objective

The goal is to demonstrate how blockchain-based decentralized authentication can:

Enhance security, integrity, and confidentiality

Reduce unauthorized access risks

Integrate with SQL Server while maintaining interoperability and acceptable performance

Conceptually align with GDPR and HIPAA data protection principles

Functional Requirements

The system must:

Allow user registration (e.g., doctors and patients).

Implement authentication using a smart contract on a blockchain network.

Store authentication hashes or validation logs on blockchain (no medical data on-chain).

Store medical records exclusively in Microsoft SQL Server.

Validate authentication via blockchain before granting access to SQL Server.

Log authentication events for traceability.

Technical Requirements

Blockchain platform (Ethereum or similar test network)

Smart contract implementation

Backend (Node.js or Python preferred)

Microsoft SQL Server integration

Clear architecture diagram

Documentation explaining authentication flow and integration strategy

Deliverables

Full source code

Functional smart contract

SQL Server database schema

Architecture diagram

Installation guide

Technical documentation (I must fully understand the system for academic presentation)

Timeline

3–6 weeks.

Please include:

Your proposed technical architecture

Relevant blockchain experience

Estimated cost and timeline
