Use of blockchain in health sensor networks to secure information integrity and accountability

Abstract

Accountability and integrity are likely to play a key role in emerging health sensor network environments. Since health sensor devices are low capability devices, they are particularly susceptible to modern cyber threats. Blockchain technology is an emerging security technology that was explored by researchers in the past few years. Blockchain technology has been designed to protect information integrity and accountability. In a distributed manner making forgery and destruction of data can be very difficult. In this survey paper, we are specifically focused on how blockchain platforms adopt to the healthcare industry and achieve data integrity and accountability. Also, we will discuss the benefits and challenges of blockchain technology, and future blockchain research directions. Blockchain technology can be used to prevent unauthorized information access and enhance the security of sensor data. The use of blockchain technology in health sensor networks may address many of the integrity and accountability concerns of health sensor networks.
