This has helped the NCA bust a number of trafficking rings, according to Santander. Jas Narang, Santander UK’s chief transformation, data and AI officer, told PA: “At Santander, we have implemented an AI tool to detect suspicious activity on customers’ accounts – helping us uncover potential cases of human trafficking and escalate them to the National Crime Agency. “When it comes to more complex and evolving types, such as human trafficking and modern slavery, these rigid systems simply can’t keep up,” said Mr Narang. On their own, they may not seem suspicious but the AI tool helps spot the patterns behind the payments and the subtle indicators of exploitation. The banking giant is looking at rolling out the AI tool more widely across its global operations and at using it to help detect other types of crime.
