Securing IoT with Blockchain-Based System for Attendance Management

In every organization, managing the attendance of personal is an important task. Student attendance management is a critical study aspect in academic institutes. In the initial era of education, student attendance was maintained using paper records. It has slowly advanced over a few decades. Many educational organizations use smart-card or RFID-based cards, biometric devices such as fingerprint scanners, face recognition, etc., for recording student attendance. The use of such technologies has its advantages and disadvantages. Recently Internet of Things and Blockchain has gained the attention of many researchers. Researchers are trying to use these technologies to build several applications, including Smart Home Systems, Supply Chain Management, Electronic Healthcare record management, etc. However, an IoT network has constraints on power consumption, processing power, and security of end devices in the network. On the other hand, a few issues associated with blockchain are storage limitation, data privacy, consent revocation, energy consumption, scalability, and performance. In this paper, an Blockchain-Based integrated with Internet of Things (IoT) Data Sharing System for student attendance management is proposed. The paper also addresses the issues of authentication and access control. We introduce a multifaceted authentication system for user device substantiation, PKI-RSA-based blockchain implementation for data sharing, and a rule-based access control scheme to access the blockchain data. The predominant implementation details of the proposed system are explained in this paper.
