- Recall (Sensitivity): The percentage of actual fraudulent transactions that are correctly identified. High recall is crucial for minimizing missed fraud cases. A recall of 90% means that the system identifies 90% of all fraudulent transactions.
- False Positive Rate: The percentage of legitimate transactions incorrectly flagged as fraudulent. Minimizing this is vital for operational efficiency. A low false positive rate means fewer resources are wasted investigating false alarms.
- Investigation Time: The average time taken to investigate a flagged transaction. Faster investigations are more efficient.
- Cost per Fraud Case Identified: This KPI considers the resources spent on investigation, technology, and personnel against the value of fraud prevented.
A balanced view of these KPIs is essential; solely focusing on a single metric (e.g., high detection rate) might lead to an increase in false positives, negatively impacting overall system effectiveness.
Q 10. How do you prioritize fraud investigations?
Prioritizing fraud investigations requires a structured approach that balances risk and efficiency. I typically use a risk-scoring system that combines several factors:
- Monetary value: Higher value transactions are prioritized, as the potential loss is greater.
- Transaction type: Certain transaction types might be inherently riskier (e.g., international wire transfers).
- Customer risk profile: Customers with a history of suspicious activity are given higher priority.
- Alert score: The confidence level assigned by the fraud detection system, based on the model’s prediction.
- Time sensitivity: Time-sensitive transactions, such as those involving perishable goods, are prioritized for swift investigation.
I use a combination of automated scoring and human oversight. The automated scoring helps to quickly filter and prioritize alerts, while human analysts review the higher-risk cases, ensuring thorough investigation and judgment based on contextual factors not always captured in algorithms.
Imagine a scenario where we have several fraud alerts. An alert involving a $10,000 international wire transfer from a high-risk customer with a high alert score would naturally be prioritized over an alert involving a small, local transaction from a low-risk customer with a low alert score. This prioritization method makes sure we focus our resources where they matter most.
Q 11. How do you handle false positives in fraud detection systems?
False positives, while unavoidable, can significantly hamper efficiency and erode trust. Addressing them requires a multi-pronged approach:
- Refine the model: Analyze the characteristics of false positives to identify patterns. This often involves adjusting model parameters, adding or removing features, or exploring different algorithms to improve accuracy.
- Improve data quality: Inaccurate or incomplete data can lead to false positives. Implementing robust data validation and cleansing processes are critical.
- Investigate and learn: Each false positive presents a learning opportunity. Analyze the reasons behind the incorrect flagging to identify weaknesses in the system.
- Implement a review process: Establish a system where human analysts review alerts before escalating them for full-scale investigation. This adds a crucial layer of human intelligence and judgment.
- Feedback loop: Use feedback from investigations to continuously improve the model’s performance. This feedback loop is crucial for iterative improvement.
For example, if a model consistently flags legitimate transactions from a particular merchant, we would investigate whether there’s a problem with how the model uses data related to that merchant. Perhaps the data is faulty, or the features used to represent that merchant’s transactions are not sufficiently descriptive.
Q 12. What is your experience with regulatory compliance related to fraud?
