In this white paper, we address the challenge of credit card fraud detection with our open source engine, Kamanja. The paper is aimed at executives and technical people who deploy solutions to credit card fraud.

We discuss the problem of fraud on a broad scale, and then focus on credit card fraud detection, including supervised and unsupervised learning. Then we review current credit card fraud detection solutions, and explore the part Kamanja can play in a detection system.
