This technique uses predefined rules to identify fraud. These rules are based on what is considered normal and what is suspicious.
Example: Flagging transactions over $10,000 in a personal account.
Advantage: Simple and quick to implement.
Limitation: Can miss new fraud patterns.<\/p>\n\n\n\n

Machine learning algorithms analyze large datasets to find unusual patterns that indicate fraud. These models improve over time as they learn from data.
Example: Identifying unusual spending patterns on a credit card.
Advantage: Effective at detecting complex fraud.
Limitation: Requires good-quality data and technical expertise.<\/p>\n\n\n\n
This technique looks at how users behave to spot changes that might indicate fraud.
Example: A customer usually shops locally, but a sudden purchase happens in a foreign country.
Advantage: Focuses on personalized behavior.
Limitation: False positives may occur when users genuinely change habits.<\/p>\n\n\n\n
Graphs, charts, and heatmaps are used to visualize transaction data. Patterns or outliers in the data can signal fraud.
Example: A spike in small transactions over a short period may indicate money laundering.
Advantage: Easy to interpret and explain findings.
Limitation: Works better with smaller datasets.<\/p>\n\n\n\n
This uses historical data to predict where fraud might happen. It combines statistical techniques and machine learning to forecast risk.
Example: Predicting fraud in areas with a history of scams.
Advantage: Helps prevent fraud before it occurs.
Limitation: Depends on the availability of past data.<\/p>\n\n\n\n
This technique monitors transactions across multiple channels, such as online banking, ATMs, and in-person branches, to spot unusual patterns.
Example: A login from one country followed by a cash withdrawal in another.
Advantage: Provides a complete view of activity.
Limitation: Complex to implement across systems.<\/p>\n\n\n\n
These systems monitor transactions as they happen, allowing immediate action if fraud is suspected.
Example: Declining a credit card transaction if the system detects it as suspicious.
Advantage: Reduces the impact of fraud.
Limitation: High costs and potential delays for genuine customers.<\/p>\n\n\n\n
