How PayPal Boosts Security with Artificial Intelligence

To PayPal, the transactions signal fraud: a US user’s account is accessed in the UK, China, and elsewhere around the world. But PayPal’s security system - thanks to a growing reliance on an artificial - intelligence technology known as deep learning - is now able to spot possible fraud without making mistakes. That’s because algorithms mine data from the customer’s purchasing history - in addition to reviewing patterns of likely fraud stored in its databases - and can tell whether, for example, the suspect transactions were innocent actions of a globe-hopping pilot.
