Traditional methods of fraud detection

There are different methods for detecting fraud as follows

Manual audits and reviews

This involves human auditors or reviewers examining transactions, documents, or records to detect anomalies or suspicious activities. It relies on the expertise and experience of the auditors to identify patterns or irregularities that may indicate fraud.

Rule-based systems

These systems use predefined rules or thresholds to indicate transactions or activities that deviate from expected patterns. For example, if a transaction exceeds a certain monetary limit or occurs at an unusual time, it may trigger an alert for further investigation.

Limitations of traditional methods

While these methods have been effective to some extent, they also have significant limitations. They can be time-consuming, expensive and prone to human error. Rule-based systems may miss sophisticated or evolving fraud patterns that do not fit predefined rules. Additionally, manual audits are also limited by the scale of data that can be effectively reviewed within reasonable timeframes.

In recent years, advancements in technology, particularly in machine learning and artificial intelligence, have led to the development of more sophisticated fraud detection techniques that complement or enhance these traditional method
