Talk Title: Detecting Online Credit

Card Fraud: A Data Driven Approach

Talk Abstract:

A consisten

t problem plaguing online merchants today is the
growth and evolution

of online credit card fraud. Thieves
harvest credit card numbers from

a myriad of sources, place
online orders from all over the world, an

d ship to countless
drop locations. Current estimates place the proble

m at 1 to
1.5 billion dollars annually of which the online merchant
holds complete liability.

In this talk, I will describe the

problem of eCommerce fraud
and outline various detection measures that
online merchants
employ. Like many merchants, Apple Computer leverag

es
techniques from data mining, machine learning, and statistics
to efficiently discover fraud patterns and adapt to new
trends. Some
topics that I will discuss include evaluating
fraud patterns in histo

ric data, building fraud predictive
models, inferencing through orde

r linkages, and anomaly
detection.
