Secure Patient Data Management on Public Blockchain with Private Nodes (POC)

Project Overview

This repository documents a Proof of Concept (POC) exploring the feasibility of using private nodes on a public blockchain, along with OpSec technology, for secure and privacy-preserving patient data management in healthcare.

Objective

The primary objective is to evaluate the effectiveness of this approach in achieving:

• Enhanced security for sensitive patient data
• Improved patient privacy control
• Streamlined data sharing between authorized healthcare providers
• Transparent and auditable data management processes

Technology Stack

• Public Blockchain: (to be determined - Hyperledger Fabric or Ethereum with Consortium Mode)
• Private Nodes: Operated by authorized healthcare organizations within the consortium network.
• OpSec Technology: Leverages AI-powered security features for threat detection, vulnerability management, and potential secure enclave utilization.
• Encryption: Industry-standard encryption (e.g., AES-256) for data at rest and in transit.
• Smart Contracts: Govern patient consent, data access control, and audit trails.

Scenario

The POC focuses on a healthcare setting (e.g., hospital) and demonstrates functionalities for:

1. Patient Registration: Secure storage of encrypted basic demographic data and patient consent management.
2. Medical Records Creation: Secure storage of anonymized and encrypted EMR data with access control based on healthcare professional roles.
3. Data Sharing: Secure and permissioned sharing of specific data points with authorized providers upon patient consent.
4. Immutable Audit Trail: Recording all data interactions on the blockchain ledger for transparency and compliance.

POC Activities

1. Network Setup and Security: Deploying the blockchain network with private nodes, OpSec integration, and security testing.
2. Smart Contract Development: Implementing smart contracts for data management functionalities.
3. Data Management and Security: Developing functionalities for secure data encryption, anonymization, and key management.
4. User Interface Prototyping: Building a basic prototype interface for healthcare professionals to interact with the system.

Evaluation Criteria

• Security: Effectiveness of OpSec integration and overall security posture.
• Performance: Scalability and transaction processing times for real-world healthcare data volumes.
• Usability: User-friendliness of the prototype interface for healthcare professionals.
• Compliance: Alignment with relevant healthcare data privacy regulations (e.g., HIPAA).

Benefits

• Stronger security for patient data through private nodes and OpSec technology.
• Increased patient control over data through consent management.
• Efficient and secure data sharing between authorized healthcare providers.
• Transparent and auditable data management processes for regulatory compliance.

Limitations

• Technical complexity of setting up and maintaining a private blockchain network.
• Scalability challenges of public blockchains with consortium mode for high data volumes.
• Evolving regulatory landscape surrounding blockchain use in healthcare.

Next Steps

Based on the POC results, further development could involve:

• Expanding functionalities for managing different healthcare data types.
• Integrating the system with existing healthcare information systems.
• Pilot testing with a broader group of users.
• Addressing regulatory considerations for wider adoption.

Getting Started

This repository is currently under development for the POC. Further technical details and code will be added as the project progresses.

Documentation and User Experience Improvement

Project Overview

This project aims to improve the documentation and user experience of OpSec components and applications. The goal is to enhance user understanding and adoption of OpSec by providing clear, concise, and up-to-date documentation, as well as by identifying and addressing usability issues.

Tasks Completed

Documentation Enhancement Initiative

• Reviewed and updated outdated documentation for OpSec components, including tutorials, API references, and troubleshooting guides.
• Added clarifications and explanations to complex concepts and procedures.
• Incorporated user feedback to improve the accuracy and completeness of documentation.

User Experience Optimization

• Identified usability issues in OpSec applications and services, such as installation processes, configuration interfaces, and user interfaces.
• Proposed enhancements to streamline usability and accessibility for all users.
• Implemented some of the proposed enhancements, such as simplifying the installation process and adding more user-friendly features to the configuration interface.

Project Outcomes

The project resulted in the following outcomes:

• Improved documentation: The documentation for OpSec components is now more clear, concise, and up-to-date. This will make it easier for users to understand and use OpSec.
• Enhanced user experience: The usability of OpSec applications and services has been improved. This will make OpSec more accessible to a wider range of users.
