Preventing fraud at scale is not a policy exercise. It’s a data and systems challenge.
In Part 2 of this three-part series, Justin Marsico, Assistant Commissioner for Fraud Prevention and Financial Integrity at the U.S. Department of the Treasury, joins Carly Mitchell of Guidehouse to discuss how Treasury uses data and analytics to verify over a billion payments each year.
Marsico shares how payment verification works in practice, how analytics are introduced into live payment systems with zero tolerance for error, and what agencies and states should consider as they strengthen fraud and improper payment controls.
