A Framework for Secure Logging in Precision Healthcare Cloud-based Services

Cloud-based precision health care services will soon be integrated with existing health care systems. Since health care data is sensitive, it is crucial to maintain the integrity of audit logs that allow organizations to track system usage, protect patient privacy, and provide forensic evidence. In this paper, we develop a secure logging framework for precision healthcare services. We implement the framework using blockchain and show that our logging system is tamper-resistant and can ensure integrity.
