Abstract

The use of IoT devices in patient care systems is witnessing a surge. However, there are new security and privacy concerns. This paper addresses these challenges by assessing the security and privacy risks posed by healthcare IoT devices. It also offers a comprehensive framework to enhance their security. The emphasis here is placed on critical elements of security: data management, the secure transmission of data, the protection of privacy, and integrity within systems in healthcare IoT environments. The proposed solutions in the paper include some very practical measures such as data encryption, secure communication protocols, lightweight authentication, role-based access control, two-factor authentication, intrusion detection systems, and privacy-preserving data analytics. The paper also talks about how blockchain technology could help keep data safe and make it easier to verify things without a central authority. We include a case study on remote patient monitoring (RPM) to demonstrate the practical application of the framework. This case study shows how to protect patient information effectively. The paper discusses ethical concerns regarding patient consent and the proper utilization of data, aiming to reassure the reader about the responsible management of patient information and restore confidence in patients' control over their health data. Finally, the paper discusses limitations of IoT in healthcare, like interoperability issues and resource constraints. In general, this study provides intriguing thoughts and applicable options to ensure IoT healthcare devices’ security and safeguard patients’ private information within the changing environment of smart healthcare.
