Description: In this paper we present the necessary theory to
detect fraud in credit card transaction processing using a
Hidden Markov Model (HMM). An HMM is initially trained
with the normal behavior of a cardholder. If an incoming
credit card transaction is not accepted by the trained HMM
with sufficiently high probability, it is considered to be fraudulent.
