Background of the Study
Digital examinations are increasingly being adopted by universities as a more efficient and scalable method of assessing students' knowledge. Federal University, Gashua, located in Bade LGA, Yobe State, is one of the institutions leveraging digital platforms for conducting examinations. However, digital exams face several challenges, including cheating, fraud, and tampering with exam results. Traditional security measures such as passwords and firewalls may not be sufficient to prevent such issues.
Blockchain technology, known for its decentralized and immutable nature, offers a promising solution to secure digital exams. By recording every transaction or action in a decentralized ledger, blockchain ensures that exam records cannot be altered without detection. Smart contracts, which are self-executing contracts with the terms directly written into code, can further enhance security by automating exam-related processes, such as authentication and result submission, in a transparent and tamper-proof manner.
Statement of the Problem
Federal University, Gashua, is facing issues related to the security and integrity of digital examinations. With increasing instances of cheating and manipulation of results, there is a need for a more robust and secure method to protect the examination process. Blockchain and smart contracts offer potential solutions, but their feasibility and effectiveness in securing digital examinations need to be explored and validated.
Objectives of the Study
1. To investigate the application of blockchain and smart contracts in enhancing the security of digital examinations at Federal University, Gashua.
2. To develop a prototype of a blockchain-based digital examination system with integrated smart contracts.
3. To evaluate the effectiveness of blockchain and smart contracts in preventing cheating and ensuring the integrity of digital examination results.
Research Questions
1. How can blockchain and smart contracts enhance the security and integrity of digital examinations at Federal University, Gashua?
2. What are the potential benefits of using blockchain and smart contracts in securing digital examinations?
3. How effective is the proposed blockchain-based system in preventing cheating and ensuring accurate results in digital exams?
Research Hypotheses
1. Blockchain and smart contracts significantly enhance the security and integrity of digital examinations at Federal University, Gashua.
2. The implementation of blockchain and smart contracts will reduce instances of cheating and manipulation in digital examinations.
3. A blockchain-based digital examination system with integrated smart contracts will improve the transparency and accountability of the examination process.
Significance of the Study
This study will provide insights into the potential of blockchain and smart contracts in securing digital examinations, ensuring transparency, and preventing cheating. The findings will contribute to the development of more secure and efficient examination systems at Federal University, Gashua, and could serve as a model for other institutions facing similar challenges.
Scope and Limitations of the Study
The study will focus on developing and evaluating a blockchain-based digital examination system with smart contract integration at Federal University, Gashua, located in Bade LGA, Yobe State. The scope is limited to the examination process and does not extend to other administrative functions.
