Analytic Techniques for Combating Financial Fraud

Effective detection and prevention of financial transaction fraud requires analytic techniques capable of characterizing the transaction stream and determining the likelihood of fraud or misuse in real time. The nature of fraud makes the development of transaction monitoring models challenging, and inspires new Analytic innovations to respond to the ever changing tactics taken on by fraudsters. In this talk, we will review traditional payment card fraud detection analytic techniques such as transaction profiling and neural network models, and then expand to new analytic techniques. These new techniques include Adaptive Analytics which allows a model in production to adjust its scores dynamically based on analyst fraud case dispositions; Self-Calibrating Analytics which determines outlier fraud features in streaming transactions through real-time estimations of variable distributions; and Global Intelligent Profiles which enable profiling of various entities in the fraud decision such as ATMs, countries, and compromise clusters.


Scott Zoldi is a Vice President of Analytic Science at FICO. He has responsibility for the analytic development of FICO's transaction analytics products and solutions, including the FICO™ Falcon® Fraud Manager product. While at FICO, Scott has been responsible for authoring over 30 patent applications related to fraud and transaction analytics. He is actively involved in the development of FICO's new Falcon 6 product, which includes new analytic innovations such as adaptive analytics, global intelligent profiles, self-calibrating analytics and enterprise analytics. Before joining FICO, Scott was a director's postdoctoral fellow at Los Alamos National Laboratory. Scott received his Ph.D. in theoretical and computational physics from Duke University and was a DOE computational science graduate fellow.

Laws against adopting PETs (Privacy Enhancing Technologies)

As organizations look to mitigate their privacy risks, they are increasing being encouraged by regulatory authorities to consider privacy by design (PbD) and privacy enhancing technologies (PETs). PETs present an alternative to the standard model of most organizations: data collection coupled with data protection. PETs can either increase transparency, by allowing individual or collective auditing of company privacy practices (Google's Privacy Center) or increase opacity, by hiding or eliminating some of the links between data points (TOR anonymity network).

Laws and regulations can also affect the transparency and opacity of personal data. While some laws may adversely affect privacy for organizations following the standard model, other laws may directly impede privacy enhancement by requiring the collection of personal data that are not necessary for organization operations. This panel aims to look at laws and regulations that either directly or inadvertently are not PET friendly.


Peter P. Swire is the C. William O'Neill Professor of Law at the Moritz College of Law of the Ohio State University and a Senior Fellow at the Center for American Progress. Professor Swire has published extensively, testifies regularly before the Congress, and is quoted frequently in national and international press. Under President Clinton, he served as the Chief Counselor for Privacy, the only person to date to have government-wide responsibility for privacy policy. In that position, he chaired the White House Working Group on Encryption in the lead-up to the 1999 change to permit export of strong encryption. He is lead author of Information Privacy: Official Reference for the Certified Information Privacy Professional. His current research focuses on global laws governing encryption and lawful government access.

Dr. Stuart S. Shapiro is a Principal Information Privacy and Security Engineer and a member of the Privacy Community of Practice at the MITRE Corporation, a not-for-profit company performing technical research and consulting primarily for the U.S. government. At MITRE he has supported a wide range of privacy activities, including privacy impact assessments, for major government programs and coordinates MITRE research on enterprise privacy-enhancing technologies (ePETs). Prior to joining MITRE he was Director of Privacy at CareInsite, an e-health company, where his responsibilities included both policy and technical issues revolving around privacy and security. He has also held academic positions at several institutions, including the Centre for Research into Innovation, Culture and Technology at Brunel University in the U.K. and the Department of Science and Technology Studies at Rensselaer Polytechnic Institute in the U.S. He has taught courses on the history, politics, and ethics of information and communication technologies (ICTs), while his research and writing have focused on ICTs and privacy and on the history and sociology of software development.

Travis D. Breaux is an Assistant Professor of Computer Science, appointed in the Institute for Software Research of the School of Computer Science at Carnegie Mellon University. Dr. Breaux's research program searches for new methods and tools for developing correct software specifications and ensuring that software systems conform to those specifications in a transparent, reliable and trustworthy manner. This includes demonstrating compliance with U.S. and international privacy and security laws across multiple jurisdictions in finance and healthcare. Dr. Breaux has several publications in ACM and IEEE-sponsored journals and conference proceedings. Dr. Breaux is a member of the ACM SIGSOFT, IEEE Computer Society and a Council Member of the USACM Public Policy Committee.

R. Jason Cronk is licensed attorney in Florida, Certified Information Privacy Professional and currently works as a software architect in the Information Security Department of Verizon, Inc. Mr. Cronk lectures frequently on the topics of privacy and privacy by design with a special emphasis on employing PETs (Privacy Enhancing Techniques) in information systems. Mr. Cronk was an original attendee of Financial Cryptography 97, where he gave a rump session speech on using statistical sampling for authenticating streaming microcash.
