Bank fraud detection scenarios

[rhodesian]

Hi all,

I am working as a dba in a small bank and I got an assignment to develop an in-house tool for detecting fraud scenarios. I know the technical part of manipulating multiple data sources and mining data, but do you happen to know what tests/scenarios the banks use to detect fraud across all types of transactions (e.g. deposits, cards, online banking, employee fraud, wire and ACH etc). Have any of you coded such tests/scenarios? Thanks.

I doubt you will receive help with such a specific problem. Perhaps we can suggest a few things if you post what you have done.
