Machine learning is among the most powerful allies for digital platforms in their fight against fraud. Fraud schemes are becoming more sophisticated in today’s digital age, with fraudsters increasingly deploying AI and machine learning to execute sophisticated scams. As an effective countermeasure, it has become imperative for organizations to switch to machine learning-based fraud prevention solutions.

Machine learning is an advanced subset of artificial intelligence, which, unlike traditional fraud prevention methods, excels in its ability to learn from vast amounts of data and adapt to evolving threats. These algorithms can identify patterns, detect anomalies, and predict fraudulent activities with unprecedented accuracy, making machine learning an essential tool for robust and proactive fraud prevention.

The Limitations of Traditional Fraud Prevention

Fraudsters have outsmarted most existing fraud prevention methods, causing substantial financial losses to organizations. A ‘PwC’s Global Economic Crime and Fraud’ survey reveals that 40% of Indian organizations have faced losses ranging from USD 50,000 to 100,000, highlighting the urgent need for advanced fraud prevention solutions.

Traditional fraud prevention solutions often fall short in today’s digital landscape due to their reliance on static and predefined rules. These rule-based fraud prevention systems cannot detect subtle behavioral deviations, making it challenging for them to keep up with evolving fraudster tactics. The bottom line is that they are only effective when the nature of the fraud is well-known, making the platform vulnerable to potential threats that can lead to serious financial losses.

How Machine Learning Transforms Fraud Prevention?

Here are a few ways that the introduction of machine learning in fraud prevention makes a significant difference:

• Real-time detection: The fraud prevention systems with machine learning process transactional and user behavioral data in real-time. New data as flown in is compared to the established norms in real time, and the slightest deviations are flagged. Platform owners can configure the fraud detection system to temporarily block flagged accounts and send them for further review. By detecting fraud as it happens, machine learning minimizes its impact and helps safeguard the platform effectively.
• Predictive capabilities: Machine learning combined with device fingerprinting uses historical data of devices in predicting and preventing potential fraud. A unique ‘Device ID’ is assigned on the first visit. If (or when) the device is found to have unusual patterns like suspicious softwares or multiple accounts, a high-risk score is assigned to that ‘Device ID’. By keeping close tabs on risky devices, machine learning stops fraud before it happens, ensuring the platform remains secure.
• Adaptability to identify new fraud: Machine learning algorithms learn from past fraud cases to identify characteristics that typically precede fraudulent actions. These algorithms effectively discover patterns and relationships between data points and build models trained to identify those patterns once they recur in future datasets. ML-based fraud prevention models are becoming increasingly accurate as they refine their models over time as they process new data, including unmapped data points. This ongoing improvement helps them identify emerging fraud more effectively.

Real-World Examples of Machine Learning in Fraud Prevention:

An online gaming platform can use machine learning to address several key fraud prevention challenges:

1. Stop fraudulent transactions: To detect and block suspicious betting patterns and transactions in real-time.
2. Bonus abuse/collusion: To identify patterns for players working together to exploit bonus systems or in-game rewards.
3. Prevent unauthorized payments: To identify and prevent payments made with stolen credentials.
4. Protect in-game communication: To filter out scams and spam from in-game chats.
5. Safeguard in-game economy: To prevent players from monetizing assets acquired through automated tools.
