Enhancing Healthcare Data Confidentiality through Decentralized TEE Attestation

The integration of digital technologies like the Internet of Medical Things (IoMT) and Electronic Health Records (EHRs) in healthcare has significantly improved patient care. However, this digital transformation brings challenges, particularly regarding the secure computation, privacy and security of sensitive health information. This paper presents a potential solution to these challenges by combining Trusted Execution Environments (TEEs) with a decentralized attestation mechanism. Unlike traditional centralized attestation, the proposed approach leverages blockchain technology to ensure transparency, immutability, and enhanced security. This research outlines the benefits, discusses potential threats to validity, and suggests future work to further secure healthcare data processing, ultimately aiming to create a more robust and resilient system for protecting sensitive patient information.
