The British Computer Society claimed that, with more than 55 000 mobile handsets lost in London's black cabs every year, Londoners are four times more likely to be victims of identity theft through data loss than anyone else in the UK.
Drawing on a survey of 300 London black cab drivers, the British Computer Society reported that London has become a `black spot' for data loss, and that young, single professionals are the most vulnerable demographic.
To help combat the data loss problem, the British Computer Society launched a taxi cab advertising campaign asking Londoners to be aware of the risks associated with data loss and advising them on how to take measures against it.
"Poor information management hurts people and corporations", said David Clarke, the British Computer Society's chief executive.
"Londoners must realise that losing their phones, laptops, handbags or briefcases is like giving a thief the keys to your home. It's time to take more care of your personal data."
According to Clarke, mobile phones are not the only portable devices left in London's taxi cabs, as researchers found that - on average - London people left an additional 6193 devices, including laptops, in black cabs over the last 12 months.
"It is important that people protect their own information", said David Smith, the British Computer Society's deputy information commissioner. "This initiative will help make sure that personal information does not end up in the wrong hands."
Delving into the research reveals that ID theft hot spots in London include Kensington, Victoria, Clapham Junction and Hammersmith.
