In this chapter we will cover both detection and investigation.

When deploying your fraud detection capabilities, you will address questions such as

  • How to allocate capabilities between prevention, detection, and investigation? What technologies to deploy for each?
  • When and for what to use deterministic versus stochastic technologies?
  • What methods, models, or techniques should you use?
