AI helps in fraud fight

Alliance & Leicester says it has saved millions of pounds of potential losses from credit card frauds with the introduction of an artificial intelligence-based detection system.

Proactive Risk Manager, Credit Edition, from ACI Worldwide, detects fraud and identifies behaviour that could indicate an intent to defraud. The system uses a combination of rules and the pattern-matching and recognition capabilities of neural networks to alert managers to suspicious activity.

Head of group fraud and corporate security for Alliance & Leicester, Geoff Lloyd, said, "The ability to be able to analyse and report on a full extract of our credit card transaction data has been an advantage in identifying and targeting sophisticated fraud."

Martin Hewgill, fraud specialist at ACI, said, "Neural networking can use data collected on fraudulent dealings to strengthen the system." But both men emphasised that these are only an aid to human decision-making.
