Big data can unlock the future of fraud prevention

by Guest Contributor 3 min read October 21, 2014

More than 10 years ago I spoke about a trend at the time towards an underutilization of the information being managed by companies. I referred to this trend as “data skepticism.” Companies weren’t investing the time and resources needed to harvest the most valuable asset they had – data.

Today the volume and variety of data is only increasing as is the necessity to successfully analyze any relevant information to unlock its significant value. Big data can mean big opportunities for businesses and consumers. Businesses get a deeper understanding of their customers’ attitudes and preferences to make every interaction with them more relevant, secure and profitable. Consumers receive greater value through more personalized services from retailers, banks and other businesses. Recently Experian North American CEO Craig Boundy wrote about that value stating, “Data is Good… Analytics Make it Great.”

The good we do with big data today in handling threats posed by fraudsters is the result of a risk-based approach that prevents fraud by combining data and analytics. Within Experian Decision Analytics our data decisioning capabilities unlock that value to ultimately provide better products and services for consumers.   The same expertise, accurate and broad-reaching data assets, targeted analytics, knowledge-based authentication, and predictive decisioning policies used by our clients for risk-based decisioning has been used by Experian to become a global leader in fraud and identity solutions.

The industrialization of fraud continues to grow with an estimated 10,000 fraud rings in the U.S. alone and more than 2 billion unique records exposed as a result of data breaches in 2014. Experian continues to bring together new fraud platforms to help the industry better manage fraud risk. Our 41st Parameter technology has been able to detect over 90% of all fraud attacks against our clients and reduce their operational costs to fight fraud.

Combining data and analytics assets can detect fraud, but more importantly, it can also detect the good customers so legitimate transactions are not blocked. Gartner reported that by 2020, 40% of enterprises will be storing information from security events to analyze and uncover unusual patterns. Big data uncovers remarkable insights to take action for the future of our fraud prevention efforts but also can mitigate the financial losses associated with a breach. In the end we need more data, not less, to keep up with fraudsters.

Experian is hosting Future of Fraud and Identity events in New York and San Francisco discussing current fraud trends and how to prevent cyber-attacks aimed at helping the industry. The past skepticism no longer holds true as companies are realizing that data combined with advanced analytics can give them the insight they need to prevent fraud in the future.

Ask the Expert: Unlocking the ROI of alternative data with Natasha Madan and Julius Heim

A visibility gap lenders can't afford to ignore Alternative data is often associated with thin-file or credit invisible consumers. But its value extends far beyond those segments. Experian's Clarity Services database includes approximately one in five credit-active consumers, including one in four consumers with prime-and-above credit profiles. That means lenders may be missing important signals, not only for emerging borrowers, but also for applicants who appear well qualified using traditional bureau data alone. Consider two consumers with the same credit score. Based on traditional credit data, they may appear equally creditworthy. But when Clarity data is added, one consumer may demonstrate stable repayment behavior while another shows recent defaults on alternative finance products. The credit score hasn't changed, but the decisioning context has. That's where alternative data creates value: helping lenders distinguish between consumers who look similar on paper but represent very different levels of risk and opportunity. In this Ask the Expert session, Experian’s Julius Heim, Vice President of Analytics Product Build, Innovation and Scores, and Natasha Madan, Senior Director, Analytics Consulting, explain how different alternative data assets solve different business challenges and why the greatest return comes from using them together throughout the credit lifecycle. What that visibility gap is really costing lenders Better visibility matters because every lending decision carries consequences. Without alternative data, lenders may approve applicants whose repayment behavior suggests elevated risk but isn't reflected in a traditional credit file. Without cash flow insights, they may decline consumers who appear thin file on bureau data despite demonstrating strong income and responsible financial management. The result is a two-sided cost: avoidable bad debt on one side and missed growth opportunities on the other. But ROI extends beyond approvals alone. It also appears through stronger marketing strategies, improved conversion, reduced friction and more precise risk segmentation throughout the lending lifecycle. "ROI can mean many things ... marketing to the right people, achieving better approval rates, reducing risk, getting less friction and overall profitability."Julius Heim, Vice President of Analytics Product Build, Innovation and Scores Where alternative data creates ROI Improve approval strategies Use additional consumer signals to recover creditworthy applicants while avoiding unnecessary declines. Reduce portfolio risk Identify elevated repayment risk earlier through enhanced visibility beyond traditional bureau data. Improve portfolio performance Increase conversion, reduce friction and strengthen profitability across the credit lifecycle. Different data. Different jobs. Not all alternative data solves the same problem. Clarity Services can help lenders strengthen decisions early in the customer journey. It provides additional visibility during prospecting and acquisition, helping identify potential risk before an application moves through the underwriting process. Cash flow insights can provide value in a different way. When traditional credit information offers part of the picture, consumer-permissioned cash flow data can provide greater insight into income, spending patterns and financial capacity. That makes it especially valuable as a second look during underwriting. Together, these complementary data assets help lenders improve decisioning throughout the credit lifecycle. They can support acquisition, underwriting, account management and collections while building on the trusted foundation of traditional bureau data. Research also continues to demonstrate measurable lift when cash flow insights are combined with traditional credit information. "I recently did a study with a client where we actually saw a 20% lift in KS [Kolmogorov-Smirnov] above and beyond credit bureau data. Again, the bureau data itself was very predictive. But even from the cash flow data, we still got a 20% lift, which is an amazing stat." Julius Heim, Vice President of Analytics Product Build, Innovation and Scores The greatest value comes from using these data sources together for a more holistic consumer view. Start with proof, then build Adopting alternative data doesn't have to begin with a large transformation. A practical first step is a data study. By comparing current decision strategies with enhanced data, lenders can identify where additional visibility creates measurable lift within their own portfolios. This approach allows institutions to validate results before making broader operational changes. Every lender has different workflows, technology environments and business priorities. A flexible implementation strategy helps organizations incorporate new data in ways that support existing processes rather than disrupting them. Three ways to get started Run a data study Benchmark current decision strategies and quantify potential lift. Start simple Begin with targeted data attributes or proven scores before expanding to more advanced use cases. Build with confidence Scale implementation based on measured business outcomes and organizational priorities. This approach allows lenders to validate results, build confidence and expand their strategy over time. Explore alternative data with a trusted partner Every lending decision benefits from better consumer insight. Experian helps lenders combine trusted credit data with alternative data, cash flow insights and advanced analytics to strengthen decisioning, improve portfolio performance and uncover new opportunities for growth. Whether you're evaluating alternative data for the first time or expanding an existing strategy, Experian can help you identify where additional consumer insight can create measurable business value.
