Abstract:
In recent years, Internet of Things (IoT) technology is recognized as a technological revolution used in different sectors, especially those with the emerged automation concept. It has many applications in various fields, for instance, smart cities, retail, healthcare, etc. However, many issues are yet to be fully addressed, such as scalability, connectivity, privacy and security. Blockchain technology has emerged as a promising solution for privacy and security challenges. It uses a decentralized distributed ledger, which records digital assets’ information and keeps these records immutable and then reduces fraud risk. This paper proposes a Blockchain-based medical data protection system that enables users to control over their sensitive data collected from wearable sensors. Patients can upload medical records and healthcare providers can retrieve data while preserving sensitive health information against potential threats. We present a prototype implementation based on Quorum Blockchain and evaluate its memory and CPU time overheads using quorum profiling tool. The empirical results show that the integration of Blockchain technology with existing IoT systems is feasible and provides effective performance and security.
