PRIVACY PRESERVING SECURITY MECHANISM FOR IOT BASED DISTRIBUTED SMART HEALTHCARE SYSTEM

Abstract

Data security and privacy are one of the key concerns in the Internet of Things (IoT). Usage of IOT is increasing in the society day-by-day, and security challenges are becoming more and more severe. From a data perspective, IOT data security plays a major role. Some of the sensitive data such as criminal record, military information, the medical record of the patients, etc. Due to the size and other features of IOT, it is almost impossible to create an efficient centralized authentication system. The proposed system focused on IoT security for distributed medical record to provide perimeter security to the patient. Building trust in distributed environments without the need for authorities is a technological advance that has the potential to change many industries, the IOT is one among them. Furthermore, it protects data integrity and availability. It improves the accessibility of data by using the indexing method along with the blockchain. Moreover, it facilitate the utility of tracking the previous history of the patient record using the hyper ledger with authorization.
