Knowledge Based Authentication is always about the data

Updated: November 6, 2024 by Guest Contributor 2 min read March 2, 2010

When a client is selecting questions to use, Knowledge Based Authentication is always about the underlying data – or at least it should be.  The strength of Knowledge Based Authentication questions will depend, in large part, on the strength of the data and how reliable it is.  After all, if you are going to depend on Knowledge Based Authentication for part of your risk management and decisioning strategy the data better be accurate.  I’ve heard it said within the industry that clients only want a system that works and they have no interest where the data originates.  Personally, I think that opinion is wrong.

I think it is closer to the truth to say there are those who would prefer if clients didn’t know where the data that supports their fraud models and Knowledge Based Authentication questions originates; and I think those people “encourage” clients not to ask.  It isn’t a secret that many within the industry use public record data as the primary source for their Knowledge Based Authentication products, but what’s important to consider is just how accessible that public record information is.  Think about that for a minute.  If a vendor can build questions on public record data, can a fraudster find the answers in public record data via an online search?

Using Knowledge Based Authentication for fraud account management is a delicate balance between customer experience/relationship management and risk management.  Because it is so important, we believe in research – reading the research of well-known and respected groups like Pew, Tower, Javelin, etc. and doing our own research.  Based on our research, I know consumers prefer questions that are appropriate and relative to their activity.  In other words, if the consumer is engaged in a credit-granting activity, it may be less appropriate to ask questions centered on personal associations and relatives.  Questions should be difficult for the fraudster, but not difficult or perceived as inappropriate or intrusive by the true consumer.  Additionally, I think questions should be applicable to many clients and many consumers.  The question set should use a mix of data sources: public, proprietary, non-credit, credit (if permissible purpose exists) and innovative.

Is it appropriate to have in-depth data discussions with clients about each data source?  Debatable.  Is it appropriate to ensure that each client has an understanding of the questions they ask as part of Knowledge Based Authentication and where the data that supports those questions originates?  Absolutely.

Mortgage Underwriting Moves from Modernization Talk to Action 

Mortgage underwriting is entering a new phase. In a recent conversation with HousingWire’s Allison LaForgia, Michele Bodda, Group President of Experian Housing, Verification Solutions, and Employer Services, discussed how modern credit scores, alternative data and verification tools are changing how lenders evaluate borrowers.  Lenders can now judge modernization by its results, Bodda said. “Now we’re actually letting more modern scores get into underwriting to help price loans and go all the way through to securitization,” she told HousingWire. “We’re letting the scores and the data actually speak for itself instead of just talking about it.”  The Right Data at the Right Time  Modernizing underwriting means providing useful information at the right stage, rather than giving lenders everything at once. “You don’t need everything all at once. You don’t need everything on initial pull,” Bodda said.  Alternative data, such as rental payments and buy now, pay later activity, can help show how consumers manage obligations, especially those with thinner credit files. A thin credit file does not necessarily mean someone has a thin financial life.  “It’s our responsibility as one of the primary data providers to make sure we can make all of that available, so that we’re best representing the consumer,” Bodda said. A fuller view of data may help lenders identify creditworthy applicants who might otherwise be difficult to assess.  Simplifying Verification and Reducing Friction  Bodda also shared how Experian is making credit information more easily accessible and reducing unnecessary costs during the originations process, explaining that new enhancements to Experian’s Power Profile Plus allow lenders to pull credit data at the start of underwriting and request another score later without repurchasing the data.  “You can pull it later and not pay for the credit data again,” Bodda said.   Experian is also investing in income and employment verification, including through a new partnership with Workday. Bodda explained that Experian will continue to focus on process improvement, competition and innovation across the mortgage ecosystem.  A Broader Path to Homeownership  As consumer expectations and underwriting capabilities evolve, borrowers want a process that reflects their financial lives, while lenders seek greater efficiency. Modern scores, relevant data, and streamlined verification can help lenders assess applications with more context—and may help more people pursue homeownership.  “If we as an industry can open this up and bring more people into the process, then we’re going to thrive,” Bodda said in the interview.   Watch the interview and hear all of Michele’s insights, and more here.
