Abstract—The enormous impact of erroneous student examination results due to wrongly computed results, erring user authentication and loss of data integrity demands meticulous student result computation, secure storage and secure transmission of examination results. This paper describes our attempt to improve the integrity of students’ examination results during transmission and storage through the use of encryption and cryptographic hash functions to provide information security objectives of confidentiality, integrity and authenticity assurances on data. The study was guided by three (3) objectives. A baseline study was conducted to determine the challenges faced by Zambia’s Technical Education Vocational and Entrepreneurship Training Authority (TEVETA) and students regarding dissemination of students’ examination results in order to address objective number one. The results from the study indicate that the current TEVETA examination process cycle and business processes have a number of irregularities. These include storage, dissemination and how students access the examination results. The results from the baseline study were used to come up with the model which was then used to develop the proposed prototype in order to address the second and third objective. The developed prototype from our model shows that our system provides secure storage and transmission of examination results. This is largely because of the encryption and hashing introduced during storage and dissemination of the results.
