According to CyberSource Corporation, one per cent of online revenues in 2012 was lost to fraud -- that's £2.17 billion globally. Pat Phelan is cofounder of Cork-based company Trustev, which uses social and behavioural data to detect fraud. Phelan explains his real-time strategies.

IP addresses

Triangulate the addresses. Does the IP address match the delivery address? Does the browser ID match the IP and the device address?

Date of birth

To spot a fake on Facebook, Trustev starts with your birthday. "It's a direct relationship to your friends'," Phelan says. Your real friends' ages tend to correlate.

Twitter

Someone tweeting at 3pm and immediately getting five replies from bots is a giveaway. "Fake social-media identities are very patterned. Chaos indicates a real person."

Browser

Proxies and VPNs arouse suspicions. Trustev also checks the browser: "Are you running IE9, Safari or Chrome? If it's IE9, why does your computer have 20 Chrome extensions?"

Behaviour

Real shoppers browse a site before buying. Frauds typically go from landing on a site to check-out in five clicks: "Their speed is forward, forward, forward."
