Abstract	Ensuring that sensitive data is secure and accessible at all times is very important, especially in healthcare systems. In this research, HealthChain is proposed, a secure system that uses RBAC, combines ABE with blockchain technology and helps manage electronic health records (EHRs) by decentralization. Defining people’s roles as static and lacking strong audit controls are problems with conventional access control models that make them inefficient and easy to exploit. To address the issues above, HealthChain uses dynamic access control which ensures access is given according to who uses the system and what they are doing right now. Because of blockchain, logging remains unalterable, contracts are managed automatically by smarts and cloud services make it possible to enhance data handling. According to comparisons, using this hybrid strategy supports stronger data privacy, better operations and compliance with laws such as HIPAA and GDPR.
