Blockchain-based Framework for Online Entrance Examination and Score Card Verification System

Abstract

Entrance examinations are a means through which universities select prospective students for admission. Most of the entrance exams are conducted using pen-paper in an offline mode where the number of students appearing is also very high. The current entrance examination system with centralized servers to prone to single point of failure and faces threats with respect to leaks in question papers, copying by students during the exam, impersonation, manipulation of the answers, forging the score cards, difficulty in verifying the authenticity and reliability of score cards by the university, etc. To overcome these issues and to conduct entrance exams online in a secure manner and to make the process of verifying the score card easier, a framework based on private blockchain is proposed in this paper.

A Hybrid Framework of Blockchain and IoT Technology in the Pharmaceutical Industry: A Comprehensive Study

“…Plotnikov and Kuznetsova [32] proposed using an IoT solution to provide real-time location tracking with a wireless sensor placed within the medicine packaging and blockchain as an immutable ledger for data storage. Another study ofered a counterfeit prevention system that tracked medications from the manufacturer to the end user [33]. In the proposed model, manufacturers of the medication control and record all blockchain transactions.…”
