This paper described the major challenges associated with existing methods of voting; hence a prototype online voting system was developed and proposed for credible election in Edo state with a mind set to trash out the various problems identified with the existing system. In order to determine if the prototype online voting system developed is of standard performance a fuzzy clustering means (FCM) was designed to evaluate and ascertain its performance based on certain criteria gathered using questionnaire designed. The FCM model was simulated and tested for evaluation taking into consideration stakeholders of election that were drawn from twelve (12) local government areas, out of the Eighteen (18) local government areas of Edo state. Opinions of stakeholders of the election concerning the wished-for model were arbitrarily sampled and analyzed for the use of assessment in particular when compared to the present system of selection. In addition, other factors that can promise an open and just election were also discussed and place into consideration throughout the implementation of the developed prototype online voting system. The result from the evaluation revealed that the seven (7) local government areas which formed about (58.33%) of the beyond least standard cluster and the five (5) local government areas, which also formed about (41.66%) of the regular standard cluster of the entire population of (12) local government areas were both above the average acceptable benchmark for elections, which is a key indicator that the developed prototype online voting software meets more than the standard for a credible election process and it is therefore proficient as a verdict announcer for a transparent electoral process when fully implemented and deployed for usage.
