A fraud-free and credible election is a necessary ingredient to the growth of democracy. Election malpractices and violence, from 1959 till date, have offered major challenges to the Nigerian political system. To achieve a sustainable democracy in Nigeria, it is important to build public trust by ensuring the security and preservation of electoral data. The world has gradually moved into the Fourth Industrial Revolution (4IR), an era where artificial intelligence, big data, internet of things, robotics, blockchain, cloud computing and 3-D printing technologies dictate the pace of activities in all walks of life. This paper suggests specific 4IR technologies solutions to electoral data security and preservation challenges. It also suggests that the Nigerian Government announce policies to serve as catalysts for the Independent National Electoral Commission and stakeholders to harness these developments to ensure that electoral processes benefit from these technologies.
