Public auditing for real-time medical sensor data in cloud-assisted HealthIIoT system

Abstract

With the advancement of industrial internet of things (IIoT), wireless medical sensor networks (WMSNs) have been widely introduced in modern healthcare systems to collect real-time medical data from patients, which is known as HealthIIoT. Considering the limited computing and storage capabilities of lightweight HealthIIoT devices, it is necessary to upload these data to remote cloud servers for storage and maintenance. However, there are still some serious security issues within outsourcing medical sensor data to the cloud. One of the most significant challenges is how to ensure the integrity of these data, which is a prerequisite for providing precise medical diagnosis and treatment. To meet this challenge, we propose a novel and efficient public auditing scheme, which is suitable for cloud-assisted HealthIIoT system. Specifically, to address the contradiction between the high real-time requirement of medical sensor data and the limited computing power of HealthIIoT devices, a new online/offline tag generation algorithm is designed to improve preprocessing efficiency; to protect medical data privacy, a secure hash function is employed to blind the data proof. We formally prove the security of the presented scheme, and evaluate the performance through detailed experimental comparisons with the state-of-the-art ones. The results show that the presented scheme can greatly improve the efficiency of tag generation, while achieving better auditing performance than previous schemes. Graphical abstract

Certificateless Public Auditing for Cloud-Based Medical Data in Healthcare Industry 4.0

“…Te vision of Industry 4.0 creates great potential for optimizing production and services in many industrial sectors, improving productivity, reliability, and fexibility [1]. Tis is especially true for healthcare, where cyber-physical systems, big data analytics, and cloud computing are revolutionizing the entire healthcare ecosystem and moving it toward Healthcare Industry 4.0 [2,3]. Te fundamental principle of Healthcare Industry 4.0 is to provide better services to patients and improve the efectiveness of the healthcare industry by connecting all medical components, including hospitals, medical professionals, and patients [1][2][3].…”
