Is It Fraud or New Behavior? Two Analytics to Tell the Difference
Is It Fraud or New Behavior? Can you tell the difference? ©2014 Fair Isaac Corporation. All rights reserved. 2 Tom, a tech entrepreneur, purchases an expensive snowboard in Aspen, Colorado—a transaction that looks odd compared to his historical behavior patterns. Is it the first sign his card has been compromised by a fraudster? Or is this just new behavior by a legitimate cardholder? An instant decision—with more at stake for your bank than fraud prevention Reducing false positives—legitimate transactions referred or declined as suspicious— has a direct, immediate impact on your cardholders’perceptions of service quality. And while Tom will appreciate being alerted if fraud is underway, too many inquiries will make him wonder…

©2014 Fair Isaac Corporation. All rights reserved. 4 Two ways to turn Tom’s perception around New analytics help banks protect his account and customer experience by: 1 Understanding more about what Tom typically does 2 Understanding what Tom doesn’t do (but is likely to in the future)

All rights reserved. 5 1 Understand in detail what the cardholder typically does Tom doesn’t typically purchase expensive snowboards in Aspen A fraud model would likely score Tom’s snowboard transaction as suspicious—and might decline the authorization. Trained on months or years of transactional data, it would detect high risk based on not only the unusual purchase type and location (Tom lives in New York), but historical behavior patterns of other cardholders with similar profiles. But what if the fraud model could take into consideration not only historical behavior patterns but the most current behavior going on in the production environment?

All rights reserved. 6 1 Understand in detail what the cardholder typically does Adaptive models are sensitive to short-term changes in purchasing behavior An adaptive model, working in conjunction with the fraud model, refines detection by comparing Tom’s transaction to other recent activity—both known fraud and non-fraud data. It turns out it’s not just Tom with a new-found interest in snowboarding. The adaptive model has seen lots of sporting goods purchases like this recently. Cases generated on other cardholders with similar profiles were determined to be non-fraud.

All rights reserved. 7 Here’s another way to understand Tom’s typical behavior: Like all consumers, he’s a creature of habit He may have a favorite ATM and specific amounts he typically withdraws at certain times of the day or week. Favorite stores and online vendors for certain types of purchases. Favorite travel destinations and hotels. FICO’s Behavior Sorted Lists keep track of these favorites as they change over time They add power to traditional cardholder profiles by providing a more detailed view of typical transactional patterns. That improves your ability to distinguish between normal and suspicious behavior patterns. Here’s how… Favorite gas station spend amount and frequency Favorite gas station, spend amount and frequency Favorite Wi-ﬁ cafe Favorite Wi-Fi cafe Favorite ATM and cash withdrawal amount Favorite ATM and cash withdrawal amount Favorite travel city and hotel 1 Understand in detail what the cardholder typically does

All rights reserved. 9 1 Understand in detail what the cardholder typically does Fraud risk is lower if even some aspects of the transaction match cardholder favorites When Sarah purchases an expensive toy during a business trip to New York City, the transaction goes through without a hitch. One of Sarah’s favorite purchase categories in Phoenix, where she lives, is high-end children’s toys and clothing. Even with no favorites match, there is a way to anticipate new cardholder behavior Remember our snowboarder Tom? He’s never purchased snowboarding or skiing equipment, and he’s never been to Aspen before. Still, fraud analytics predict that this behavior is likely… Flip the page to find out about innovative analytic technology being developed by FICO

FICO’s Collaborative Profiles generate“archetypes” from these global behavioral patterns When this new technology, currently under development at FICO, is incorporated into fraud detection, fraud models will be able to accurately predict new customer behavior. That includes transactional behavior never before seen on Tom’s account, but which is nevertheless likely based on the archetypes he fits.

The wider the change in archetype distribution, the riskier the transaction Is this Tom buying the snowboard? Or is it a fraudster who has stolen his card or data?

All rights reserved. 12 It’s probably Tom, since buying a snowboard is something he’s statistically likely to do He has a strong allocation to “Sports Enthusiast,” which has a high propensity to spend on this kind of equipment. The fraud model incorporates that information and lowers the fraud risk score. On the other hand, he’s not likely to buy a painting from a gallery in Soho Tom has a very low allocation to the archetype, “Artsy,”with its propensity to purchase art and high fashion. 2 Understand what the cardholder doesn’t do (but is likely to) Distribution if transaction goes through 34.9% 0.5% 27.2% 42.1% 0.8% 28.2% 20.5% 29.6% 40.3% 0.3% Distribution if transaction goes through 34.9% 0.5% 27.2% 42.1% 0.8% 40.2% 0.2% 25.6% 37.9% 0.3% other exampleother example

Later gain additional benefits with Collaborative Profiles. These new analytic techniques will work together to help you do even more to protect customer accounts and deliver a superior customer experience For example, there might be a big change in Behavior Sorted Lists but not in Collaborative Profiles. This may be a sign that the customer is traveling, or moving or has changed jobs. Gradual rather than abrupt changes in both analytics may indicate that a longer-term change, such as the adoption of a more health-conscious lifestyle and/or rising prosperity, is underway. Such insights will be valuable beyond fraud management. In fact, you will be able to… 1 + 2 Combine for even more valuable customer insights “What impressed us most was that, even as an industry leader, FICO has not become complacent, but continues to innovate.” CEB TowerGroup 2012
