HIDEchain: A User-Centric Secure Edge Computing Architecture for Healthcare IoT Devices

Cloud-based IoT architectures are expecting a fast data transfer rate within a limited bandwidth. But achieving a fast data transfer rate is becoming more difficult gradually, with the massive amount of data produced by the IoT devices. The concept of edge computing gives a solution to this problem and provides fast interaction between data centers and IoT devices. With the help of edge computing, the data transfer rate has been increased drastically within a limited bandwidth. As a result, edge computing is being used in different IoT based industry including the IoT based healthcare industry. On the other hand, the distributed nature of the edge computing paradigm introduces security and privacy concerns (e.g., data theft). The IoT based healthcare solutions are getting popular among the users. Therefore, users' highly sensitive data is at high risk of theft before eventually reaching the cloud. Nowadays, these issues are being solved by introducing blockchain in different architectures. Hence, this paper is utilizing blockchain technology for providing a user-centric secure edge computing architecture for healthcare IoT devices. We are proposing to integrate blockchain to store the users' data transfer records and ensuring data security by managing the number of blockchain transactions. We are providing user-centricity by allowing users to monitor their data transactions.
