  Protected Health Information (PHI) sharing significantly enhances patient
care quality and coordination, contributing to more accurate diagnoses,
efficient treatment plans, and a comprehensive understanding of patient
history. Compliance with strict privacy and security policies, such as those
required by laws like HIPAA, is critical to protect PHI. Blockchain technology,
which offers a decentralized and tamper-evident ledger system, hold promise in
policy compliance. This system ensures the authenticity and integrity of PHI
while facilitating patient consent management. In this work, we propose a
blockchain technology that integrates smart contracts to partially automate
consent-related processes and ensuring that PHI access and sharing follow
patient preferences and legal requirements.
