A fraud detection engine is provided that analyzes transactions for fraudulent transactions. The transactions may include credit card or debit card transactions. The fraud detection engine may identify possible sources of fraud. The fraud detection engine may identify possible phony acceptors that masquerade as genuine merchants. The fraud detection engine may identify compromising points where accounts become compromised and are prone to fraudulent transactions thereafter. The fraud detection engine may receive and analyze transaction data in real-time or in batch mode. The fraud detection engine may use fuzzy logic. The fraud detection engine may use artificial intelligence such as case-based reasoning or business rules.
