BRON: A blockchained framework for privacy information retrieval in human resource management.

Area of Science:

• Blockchain Technology
• Human Resource Management
• Data Privacy and Security

Background:

• Current Human Resource Management (HRM) systems face challenges with data correctness, privacy compliance (e.g., GDPR), and transparency.
• Centralized HRM systems are vulnerable to internal data sabotage, threats, and organizational biases.
• Ineffective verifiable credential systems in existing HRM platforms hinder trust and data integrity.

Purpose of the Study:

• To address the limitations of traditional HRM systems by proposing a secure and privacy-preserving blockchain framework.
• To introduce a novel solution for global, privacy-assured data access in HRM.
• To enhance trust, fairness, and efficiency in human resource operations.

Main Methods:

• Development of a blockchain framework named Blockchained piR of resOurces as humaN (BRON).
• Integration of Privacy Information Retrieval (PIR) for privacy-based data retrieval.
• Utilization of Zero-Knowledge Proofs (ZKPs) for global verification and Proof-of-Authority (PoA) for anonymity.

Main Results:

• BRON successfully provides privacy-assured data access and decentralized human resource data management.
• Experimental results show BRON achieves 30% reduced latency and 35% better throughput compared to existing solutions.
• The framework ensures anonymity and unlinkability of HR operations through PoA.

Conclusions:

• BRON is the first blockchain framework offering effective, privacy-preserving global data access for HRM.
• The proposed system enhances data security, reduces operational inefficiencies, and promotes transparency in HR.
• BRON is a generic and customizable framework suitable for diverse HR requirements.
