Abstract
The use of learning technology has significantly improved the face-to-face learning
environments and the general adoption of the open and distance learning (ODL), which
augmented the classical learning systems. ODL Data Lake serves as primary digital repositories
for materials and resources for several individuals for the purpose of teaching and learning
activities among staff, learners’ and institutions. There are cases of insecurity arising from
learners’ interaction with learning resources from different locations. These are often possible
because of vulnerable, weak authentication schemes and the difficulty confirming learners’
identity. This further echoed the need for adequate security tool in m-learning environments to
forestall present and future issues. Therefore, the article attempted to develop an appropriate
access and authorisation scheme based on blockchain technology for preserving privacy of
learners’ sensitive data) enrolled in MLS. On the Permissioned Blockchain solution, Learners’
Data Privacy Preserving Scheme runtime (or processing time), the proposed hashing scheme
(4.95%) was higher than SHA-1 (2.30%), SHA-224 (2.23%), SHA-256 (4.28%), SHA-384
(3.51%), and SHA-512 (2.67%) for processing time. Conversely, the proposed hashing scheme
trailed behind high-performing hashing schemes: BCrypt (45.56%), and PBE (34.50%), which
revealed that, higher runtime values offered better privacy of information on the blockchain
technology and its functions.
The contributions / findings of the study were that approach helps maintain scalability while
preserving data privacy. Decentralised nature ensures that no single entity has control over the
learners' data, enhancing privacy and feature crucial for preserving the integrity of learners'
data and preventing unauthorized modifications. Finally, create a secure and privacy-preserving
environment for learners' data, ensuring that it remains confidential, tamper-proof, and
accessible only to authorised parties.
