Boxfin Case Study: Blockchain Data Storage for Health Custodial Records

This case study examines how Seal Storage Technology’s blockchain-based immutable cloud storage, built on DeStor’s decentralized storage network, is the perfect solution for retaining and storing health-related custodial records for audit purposes and empowers organizations like Boxfin Inc. and its affiliate Common Care division with cloud storage for DR/Backup purposes. 


1. Introduction



This technical use case document outlines the implementation of blockchain data storage technology for retaining health-related custodial records. It describes the problem statement, proposed solution, technical implementation details, benefits, and a practical use case scenario.


Healthcare custodial records, including patient information, medical history, and treatment data, are highly sensitive and require secure storage. The conventional methods of storing these records face challenges related to security, privacy, data integrity, and accessibility. To address these issues, blockchain technology presents a promising solution.


2. Problem Statement


Challenges in Custodial Record Storage

Traditional methods of storing health-related custodial records have limitations, including:

  • Security vulnerabilities leading to data breaches.

  • Privacy concerns and unauthorized access.

  • Risk of data tampering and loss of data integrity.

  • Limited accessibility and inefficient record sharing.


3. Proposed Solution


Blockchain Technology for Data Storage

Blockchain technology is well-suited for solving these challenges. It offers decentralized, secure, and transparent data storage. The proposed solution involves:

  • Storing custodial records on a permissioned blockchain.

  • Utilizing cryptographic encryption to protect data.

  • Implementing smart contracts to manage record access.

  • Establishing access control mechanisms for authorized users.


4. Technical Implementation


Blockchain Architecture

  • A permissioned blockchain network for custodial record storage.

  • Consensus mechanisms like Proof of Stake or Proof of Authority for validating transactions.

Data Encryption

  • Utilization of strong cryptographic algorithms to encrypt patient data.

  • Decentralized key management for enhanced security.

Smart Contracts

  • Creation of smart contracts for managing access permissions.

  • Rules for data access and sharing defined in smart contracts.

 Access Control Mechanisms

  • Role-based access control for healthcare providers, patients, and administrators.

  • Immutable logs to track data access and modifications.


5. Benefits


Security and Privacy

  • Cryptographic encryption ensures data privacy.

  • Decentralization reduces the risk of data breaches.

 Data Integrity

  • Immutable records on the blockchain guarantee data integrity.

  • Tamper-resistant data storage.


  • Authorized personnel can access records securely and efficiently.

  • Improved data sharing and collaboration among healthcare providers.


6. Use Case Scenario

Consider a healthcare institution that implements blockchain technology for custodial record storage. When a patient undergoes a medical procedure, their records are securely stored on the blockchain. Authorized healthcare providers and the patient can access and share these records using smart contracts, ensuring data privacy and integrity. All access and modifications to records are transparently logged on the blockchain.


7. Conclusion

The utilization of blockchain data storage technology for health-related custodial records addresses critical challenges in healthcare data management. It enhances security, privacy, data integrity, and accessibility, ensuring that patient data is stored and shared efficiently and securely. This use case demonstrates the potential of blockchain to revolutionize healthcare data storage and management practices.
