An Intelligent Question Paper Generator System Using Blockchain Technology

Abstract

The rapid growth of digital education has increased the demand for secure, efficient, and automated examination systems. Traditional question paper preparation is time-consuming and vulnerable to leakage and manipulation. This paper presents an Intelligent Question Paper Generator using Artificial Intelligence and Blockchain technology. The proposed system uses Natural Language Processing and large language models to automatically generate questions from uploaded syllabus documents based on Bloom’s Taxonomy levels (L1–L5). Faculty members review and approve the generated questions, which are then securely stored in an immutable blockchain ledger using SHA-256 cryptographic hashing to ensure integrity and authenticity. The system automatically formats examination papers according to university standards and exports them as secure PDF files. Experimental results show that the system significantly reduces manual effort while improving security, transparency, and consistency in examination management.
