Abstract
Global data has shown that each day the number of fraudulent transactions is exponentially increasing. As digital fraud continues to increase, machine learning and AI are being used to curb this increase. This paper will focus on the development and analysis of a machine learning model used to detect financial fraud in mobile money transactions. The aim of this paper is to discuss how effective a machine learning model can be in detecting fraud. This algorithm makes use of the Naïve Bayes model to detect fraud. To prove this, the results have been provided by using a confusion matrix, precision and recall which indicate the effectiveness of the model. The accuracy of the developed model is 0.996 with a precision and recall of both above 0.99. This work explores and develops a solution to one of the biggest breaches in digital security.
