It's easy for anyone, from criminals to stalkers, to dig up your personal information online. So is it even possible to disappear in our digital world?

Manuela Saragosa is somewhat shocked by Tony McChrystal of data security firm ReputationDefender, when he reveals the personal details he discovered about her from a cursory search on his mobile phone shortly before she interviewed him.

Silkie Carlo of pro-privacy lobby group Big Brother Watch explains why she thinks the big social media companies and online retailers need to end the implicit deal whereby they offer us free services in return for the ability to track and monetise our data.

Plus Frank Ahearn explains how his job used to be trying to trace individuals who want to disappear, such as those who have skipped bail. Today he helps clients disappear online, to escape stalkers or dangerous former business associates. He says it's not that hard to throw people off your digital trail.
