Since the advancement in computer technology, fraud has become one of the high-risk crimes in the world which needs urgent detection and prevention at an early stage. Nowadays, various kinds of fraud exist in commercial areas namely; credit card, healthcare insurance, online reviews, telecommunications, automobile, etc. Fraud can also happen internally and externally in an organization. In internal fraud an employee commits it individually, whereas external fraud involves a wide range of schemes including a third party. Therefore, a detection and prevention mechanism in the form of a computer software is essential in preventing fraud to curb further financial losses. The aim of this paper is to critically review the use of computer technology to detect and prevent fraud in selected areas. Recent computer platforms used as a tool to develop fraud detection and prevention systems are namely; spreadsheets, big data, forensic analytics, text analytics and expert systems. Based on the review, expert systems have been found to be the best option used as a future tool to curb fraud. The opportunities from this review may allow others to explore more on the technology implemented to improve fraud detection and prevention in future.
