CLOUD-DRIVEN SMART HEALTHCARE SYSTEM WITH PUBLICLY VERIFIABLE INTERNET OF MEDICAL THINGS SECURITY

Abstract

The advent of Internet-of-Medical-Things (IoMT) technology has significantly elevated the quality of life by seamlessly interconnecting biomedical sensors in the realm of e-health. Concurrently, another noteworthy technological advancement in the field of e-healthcare involves the outsourcing of medical data to the cloud. While these innovations hold immense promise, their adoption comes with challenges, most notably concerning the privacy of medical data and the resource constraints inherent in sensor devices. This article introduces a cutting-edge, secure, and efficient cloud- centric IoMT-enabled smart healthcare system with a focus on public verifiability.
A key innovation of this system is the implementation of an escrow-free identity- based aggregate signcryption (EF-IDASC) scheme, introduced within the context of this article, to fortify data transmission security. The proposed smart healthcare system seamlessly retrieves medical data from multiple sensors embedded on a patient's body, utilizes signcryption to secure and aggregate this data under the novel EF-IDASC scheme, and subsequently outsources the aggregated information to a medical cloud server through a smartphone. Notably, the system ensures the utmost privacy by safeguarding the identity and medical data of the patient, thereby addressing a critical concern in the integration of IoMT and cloud technologies for healthcare applications.

To provide a comprehensive understanding of its functionality, this article conducts an in-depth analysis of the proposed smart healthcare system's performance, specifically focusing on energy consumption. Additionally, a comparative assessment is conducted, benchmarking the performance of the proposed EF-IDASC scheme against other related schemes. Through these evaluations, this research aims to underscore the practical viability, security, and efficiency of the presented cloud- centric IoMT-enabled smart healthcare system in meeting the complex demands of contemporary e-healthcare scenarios.
