Knowledge based authentication: why it’s good to have a Babel fish

by Guest Contributor 2 min read June 10, 2010

In case you’ve never heard of it, a Babel fish is a small translator; that allows a carrier to understand anything said in any form of language.  Alta Vista popularized the name but I believe Douglas Adams, author of The Hitchhiker’s Guide to the Galaxy, should be given credit for coining the term.  So, what does a Babel fish have to do with Knowledge Based Authentication?

Knowledge Based Authentication is always about the data – I have said this before.  There is one universal truth: data doesn’t lie.  However, that doesn’t mean it is easy to understand what the data is saying.  It is a bit like a foreign language.  You may have taken classes, and you can read the language or carry on a passable conversation, but that doesn’t mean it’s a good idea to enter into a contract – at least, not without an attorney who speaks the language, or your very own Babel fish.

Setting up the best Knowledge Based Authentication configuration for risk management of your line of business can sometimes seem like that contract in a foreign language. There are many decisions to be made and the number of questions to present and which questions to ask is often the easy part.  To truly get the most out of fraud models, it is necessary to consider where the score cuts that will be used with your Knowledge Based Authentication session will be set and what methodology will be used to invoke the Knowledge Based Authentication session: objective score performance, manual review and decision, etc.  It is also important to consider the “kind of fraud” you might be seeing.

This is where it is helpful to have your very own Babel fish – one designed specifically for fraud trends, fraud data, fraud models and Knowledge Based Authentication.  If your vendor doesn’t offer you a Babel fish, ask for one.  Yours could have one of many titles, but you will know this person when you speak with them, for their level of understanding of not only your business but, more importantly, your data and what it means.  Sometimes the Babel fish will work in Consulting, sometimes in Product Management, sometimes in Analytics – the important thing is that there are fraud-specific experts available to you.

Think about that for a minute.  Business today is a delicate balance between customer experience/relationship management and risk management.  If your vendor can’t offer you a Babel fish, tell them you have fish to fry – elsewhere.

Cash Flow Insights: Powering the Next Evolution in Lending

For decades, credit data has given lenders a trusted foundation for assessing risk. Now, consumer-permissioned cash flow data is adding another layer of insight into consumers’ financial lives, including income, spending, liquidity and changing financial obligations. The opportunity is significant. Nearly one in five consumers lacks access to or has damaged credit. New Experian research also shows that 60% of consumers who have previously been denied credit or received less favorable terms than expected believe the outcome would have been different if lenders had considered their recent income and banking activity alongside their credit history. 1,2 For lenders, cash flow insights can provide additional context about a consumer’s financial capacity and support more informed underwriting decisions. The next challenge is making those insights easier to use consistently and responsibly at scale. What are cash flow insights? Cash flow insights are derived from consumer-permissioned banking data and provide visibility into how money moves into and out of a consumer’s accounts. Depending on the information available, cash flow data can provide insight into financial behaviors such as: Income and income stability: Regular and irregular income streams and changes over time Spending and recurring expenses: Everyday spending patterns and ongoing financial obligations Account balances and liquidity: Available funds and changes in account balances Debt obligations: Loan payments and other recurring debt commitments Cash flow patterns: How money moves into and out of accounts over time Traditional credit information provides a rich history of how consumers have managed credit. Cash flow insights add context about their current financial activity and capacity, providing lenders with a more complete view of financial health. Cash flow insights can also add predictive value to risk assessment. Experian analysis shows Cashflow Score can deliver up to a 25% lift in predictive performance over conventional credit scores when tailored to targeted risk tiers.3 How lenders can put cash flow insights to work at scale As interest in cash flow insights grows, the conversation is moving beyond what the data can reveal to how financial institutions can use it consistently and responsibly. That requires standardized consumer reporting, clear governance and decision-ready insights that can work within established lending processes. The launch of Experian Cashflow Data Bureau at Vision 2026 reflects this shift from access to adoption. The new consumer reporting agency operates under the Fair Credit Reporting Act (FCRA) and is designed to help financial institutions adopt consumer-permissioned cash flow insights at scale. A key part of that foundation is the cash flow consumer report, which organizes consumer-permissioned banking information into a standardized consumer report regulated under the FCRA. This gives lenders a consistent foundation for incorporating cash flow information into lending decisions while providing consumers with access to the information in their report. Turning greater visibility into better decisions The next evolution in credit isn’t about choosing between traditional credit and cash flow data. Each provides a different perspective. Traditional credit information offers deep insight into how consumers have managed credit over time. Cash flow insights can add context about financial activity and capacity. Bringing those perspectives together can give lenders greater visibility into consumers’ financial health and help them better distinguish between risk and resilience, support more informed decisions and identify opportunities to responsibly expand access to credit. As cash flow adoption continues to grow, its value will come from how effectively it complements the information lenders already use. The opportunity isn't simply to see more data. It's to turn that additional visibility into smarter, more informed decisions.
