A Comprehensive Survey on the IoT - Based Electronic Healthcare Records Security, Privacy Issues, and Countermeasures Using Blockchain Technology

The Internet of Things (IoT) is currently a widespread developing technology. Nowadays many fields are increasing their usage of IoT environments, for example, implementing it in agriculture, space, healthcare, manufacturing, construction, mining, smart homes, surveillance, and in almost every field. A great amount of data will be produced, transmitted, collected, stored, and processed in the cloud. Consequently, several threats and attacks will be increased. Security and Privacy issues have been the main cause of concern. To make it harder for attackers, IoT devices must be heavily secured. Privacy and security for everything to manage personalized data to make personalization. The IoT effectively communicates data using sensing data from remote locations to communicate to share private information. The main problem is that unauthorized users or attackers may affect the data at the time of Personal health care records, leading to the stealing of data. This paper presents a detailed survey of IoT Security, Privacy issues and countermeasures in the healthcare industry, and how to protect sensitive data. This review study intends to identify and evaluate research studies that have either been conceptualized or executed into action for EHRs management by utilizing blockchain technology. The survey looked at different research papers taken from a variety of different types of publications. The accessibility, privacy, and scalability of publications are the primary objectives of the in-depth analysis.
