Fraud Detection Rules: Types, Benefits, and Selection Tips (2024)

Accelerate AML Compliance: Meet Regulatory Demands with 80% Less Setup Time

According to the Association of Financial Professionals, fraudulent activities impacted 82% of businesses in 2018 alone. Research predicts a staggering total fraud loss of $362 billion between 2023 and 2028. This means that fraudsters are always coming up with new ways to manipulate the system. But having a strong fraud prevention strategy can actually turn the situation upside down.

What Are Fraud Detection Rules?

Fraud detection rules are essential if/then statements integral to risk management technology, aiding in decision-making. These rules work by setting conditions, like checking chargeback history or connecting device emails with IP addresses, and even verifying age or ensuring content follows the rules.

In other words, we can say that a fraud detection rule is a condition that relies on data to determine the legitimacy of an activity, enabling the review, approval, or declination of user actions. For instance, a basic rule might block website access if an IP address is flagged as fraudulent.

Rule-based fraud detection spans from simple, static rules to intricate velocity checks, assessing actions within specific time frames.

How Do Fraud Detection Rules Work?

Fraud detection rules operate in two main ways: with machine learning and without machine learning, each serving distinct purposes. In scenarios involving machine learning, the process involves data collection during user interactions, activation of machine learning for risk assessment, consultation of predefined rules, and automated decision-making aligned with those rules.

On the other hand, situations without machine learning, though usually temporary, rely on predefined rules for decision-making based on factors like geographical restrictions, emerging threats, or evolving risk thresholds.

Types of Fraud Detection Rules

Fraud management rules serve as crucial components in decision-making processes. They enable businesses to proactively detect and reduce potential fraud risks. Within a rule-based fraud detection system, not all rules are identical. Below, we discuss five distinct types of fraud detection rules:

1. Static Rules for Fraud Detection

• Basic if/then logic, often blocking user actions.
• Historical use related to IP addresses, but it can be creative based on available data.
• Notably lacks flexibility, leading to potential false positives.

2. Scoring Rules for Fraud Detection

• Inform risk strategy without necessarily blocking actions.
• Fraud scores are adaptable to business needs and can automate prevention based on thresholds.

3. Velocity Rules for Fraud Detection

• Assess user behavior through set actions over a specific time period, for instance, monitoring login attempts within a defined timeframe to prevent account takeover fraud.

4. Machine Learning Rules for Fraud Detection

• Built on artificial intelligence, learns from previous fraud cases.
• Analyzes extensive data to identify emerging suspicious patterns.
• Provides personalized suggestions based on learned insights.

8 Benefits of a Rules-Based Fraud Detection Solution
