Identity Review | Global Tech Think Tank
Keep up with the digital identity landscape.
AI fraud detection is vital — instances of fraud have skyrocketed in recent years with the expansion of the digital ecosystem, the emergence of new digital channels, and the adaptiveness of fraudsters. In 2016, global card fraud losses totaled almost $23 billion, with this number predicted to reach $44 billion by 2025.
As fraudulent activities continue to evolve in complexity and sophistication, companies face mounting challenges in preventing and mitigating fraud. With its advanced algorithms and machine learning capabilities, AI has emerged as a game-changer in fraud prevention, empowering companies to stay one step ahead of fraudsters.
Here’s a look at how companies are leveraging AI in fraud detection, prediction, and prevention to fight against fraudsters.
1. Advanced Pattern Recognition
“Fraudsters are adapting to the changes in the banking landscape — in fact, they are embracing changes! They constantly evolve tactics to systematically exploit weaknesses and vulnerabilities,” said Bob Shiflet, Executive VP at Wells Fargo, in an interview with FICO. “For banks, that means the right processes and technology must be managed by knowledgeable people to respond to any fraud scenario immediately and agilely.”
AI algorithms excel at analyzing vast amounts of data and identifying intricate patterns that are indicative of fraudulent behavior quickly and effectively. By training AI models on historical fraud data, organizations can detect anomalies and deviations from normal patterns, allowing for early intervention and prevention. These algorithms can uncover hidden connections and irregularities in real-time with reduced false positives — which cost e-commerce merchants in the US $2 billion in sales in 2018.
2. Real-Time Monitoring and Decision-Making
AI enables real-time monitoring of transactions, behaviors, and interactions, providing organizations with a proactive approach to fraud prevention. By continuously analyzing data streams, AI systems can instantly flag suspicious activities and trigger immediate responses, such as transaction blocking or alerting security teams. Real-time decision-making reduces the window of opportunity for fraudsters and minimizes potential losses.
“Mitigating risk is all about answering as many questions as possible as accurately as possible to get a clear picture of whether or not the business and individual you’re dealing with are legitimate and creditworthy. And now, with online lending, it’s also about answering these questions as quickly as possible,” said Ido Lustig, former Chief Risk Officer at BlueVine, in an interview with Mitek Systems. “So our goal with machine learning is to capture in AI as much as we can of the expertise of a seasoned loan officer — making that expertise faster and scalable.”
3. Behavioral Analysis and Anomaly Detection
AI-powered fraud prevention systems leverage advanced behavioral analysis techniques to identify deviations from normal patterns of user behavior. Users are tracked in profiles that contain information about their monetary and non-monetary transactions, from a change of address to the time period between geographically dispersed payment locations. By building comprehensive user profiles and continuously monitoring behaviors, AI can detect suspicious activities, such as account takeovers or unauthorized access attempts. Any behavioral anomalies trigger immediate alerts, enabling organizations to take prompt action.
4. Network Analysis and Fraud Networks Detection
While individual fraudsters can carry out their own attacks, fraud rings — which operate in vast, interconnected networks — have the ability to commit fraud on a much larger scale. During the COVID-19 pandemic, an identity theft ring created unemployment assistance accounts, masquerading as 19 different people to steal a total of $135,000. In 2021, a fraudster from North Carolina led a synthetic identity fraud ring, falsifying credit card information to steal more than $400,000.
While these networks can be difficult to identify, AI can be instrumental in identifying complex fraud networks and uncovering hidden connections that traditional methods may overlook. By analyzing network data and relationships among entities, AI algorithms can reveal interconnected fraud rings, synthetic identities, account takeovers, and money laundering schemes. This information assists organizations and law enforcement agencies in dismantling fraud networks and prosecuting those responsible.
5. Continuous Learning and Adaptive Analytics
One of the key strengths of AI in fraud prevention is its ability to continuously learn and adapt to evolving fraud tactics. By leveraging machine learning techniques, AI systems can refine their detection capabilities over time, incorporating new data, patterns, and fraud indicators. Using adaptive technologies can improve the effectiveness of fraud detection responses, especially in the case of marginal decisions, in which the transaction can be just above or below the cutoff.
Making these marginal decisions repeatedly can improve sensitivity to shifting fraud patterns, leading to a more precise distinction between fraudulent and non-fraudulent activity. AI-driven adjustments of machine learning predictors can greatly improve the accuracy of performance and stop new types of fraud attacks.
AI fraud prevention represents a paradigm shift in protecting organizations and customers from deceptive practices. By leveraging advanced pattern recognition, real-time monitoring, behavioral analysis, network analysis, and continuous learning, companies can bolster their defense against fraudsters. AI empowers organizations to proactively prevent fraud, safeguard trust, and preserve financial security in an ever-evolving digital landscape.
