— by, Andrew GulledgeThe intelligent use of question weighting in KBA should be a no-brainer for anyone using out of wallet questions. Here’s the deal: some authentication questions consistently give fraudsters a harder time than other questions. Why not capitalize on that knowledge?Question weighting is where each question type has a certain number of points associated with it. So a question that fraudsters have an easier time with might be worth only 50 points, while a question that fraudsters often struggle with might be worth 150 points. So the KBA score ends up being the total points correct divided by the total possible points. The point is to make the entire KBA session more punitive for the bad guys.Fraud analytics are absolutely essential to the use of intelligent question weighting. While fraud prevention vendors should have recommended question weights as part of their fraud best practices, if you can provide us with as many examples as possible of known fraud that went through the out of wallet questions, we can refine the best practice question weighting model to work better for your specific population.Even if we keep your pass rate the same, we can lower your fraud rate. On the other hand, we can up your pass rate while keeping the fraud rate consistent.  So whether your aim it to reduce your false positive rate (i.e., pass more of the good consumers) or to reduce your fraud rate (i.e., fail more of the fraudsters), or some combination of the two, question weighting will help you get there.

By: Staci Baker As the economy has been hit by the hardest recession since the Great Depression, many people wonder how and when it will recover.  And, once we start to see recovery, will consumer credit return to what it once was? In a recent Experian-Oliver Wyman Market Intelligence Report quarterly webinar, 70% of the respondents in a survey said they believe consumer debt will return to pre-2008 levels.  Clearly, many believe that consumer spending and borrowing will return, despite the fact that consumer credit card borrowing recently declined for the 24th straight month*. Assuming that this optimism is valid, what can credit card lenders do to evaluate the risk levels of potential customers as they attempt to grow their portfolios? For lenders, determining who needs credit, as well as whom to lend to in this economic environment, can be quite challenging.  However, there are many tools available to assist lenders in assessing credit risk and growing their portfolio. Many lenders look at a consumer’s credit score, such as the tri-bureau VantageScore, to evaluate their credit worthiness. By utilizing an individual’s VantageScore, a lender is able to determine potential customer risk levels. Another way to evaluate a consumer’s credit worthiness is to evaluate a population using credit attributes.  Based on the attributes a lender is looking for in their portfolio, they can see improvement in evaluating risk prediction in their portfolio using pre-determined attributes, especially those specifically designed for the credit card industry. There are also models that can help lenders predict when a consumer is likely to be in the market for a new loan or account. Experian’s In the Market Models provide lenders with product-specific segmentation tools that can be combined with risk scores to enhance the efficiency and effectiveness of their offers. To identify the optimal cross-sell and line management decisions based on an individual customer’s risk score and potential value, a lender can also utilize optimization tools.  Optimization, combined with a viable risk management strategy, can assist a lender to achieve a healthy portfolio growth in a highly constrained environment. Although lenders will need to determine the best method to meet their objectives, these are just a few of the many tools available that will assist them in correctly growing their lending portfolios. ____________________ * http://www.usatoday.com/money/economy/2010-10-07-consumer-credit_N.htm

By: Margarita Lim You may be surprised to learn that identity theft isn’t just a crime committed by an individual or individuals. There are identity theft rings that are organized and operated like corporations. A recent Justice Department press release described such an operation in New Jersey that involved 53 individuals who took part in a known fraud activity called Bust Out Fraud. Basically, the fraud ring purchased valid social security cards and then sold the social security cards to customers who then obtained driver’s licenses and other proof of identity-type cards. The fraud ring then built up the credit scores of these customers by adding them to existing credit card accounts. Once the customers with the fraudulent identities achieved good credit scores, then they opened their own fraudulent bank accounts, credit cards, lines of credit, etc.  The credit cards were used to make fraudulent purchases or rack up charges with vendors in co-hoots with the fraud ring and the fraudulent bank accounts were used to pay off the charge accounts or the charges went unpaid. Fraud trends like these cost banks, credit card companies and many others millions of dollars – costs that ultimately get passed on to you and me, the consumers. Fortunately, Experian has Fraud Products that can help companies minimize fraud losses from Bust Out Fraud as well as other types of fraud. Our BustOut Score helps decrease bust out losses by predicting and detecting bust out frauds one to three months in advance of the event happening. In addition, we have Fraud Shield Indicators or fraud alerts available on credit reports that flag when there is a recent or new authorized user added to an established credit account. Experian supports Identity Theft Prevention Programs by offering highly accurate consumer identity verification services. We’re not reliant solely on credit bureau data and are able to use multi-sourced data to confirm different components of a consumer’s identity – name, address, date of birth, etc. Our consumer authentication and fraud prevention product, Precise ID, and our knowledge based authentication product, Knowledge IQ, are highly respected in the marketplace for their reliability, quality and accuracy.
