Privacy screen filters from 3M can be attached to a wide range of devices, including laptops, tablets and smartphones, to help individuals and organisations prevent visual hacking by shielding sensitive and confidential information displayed on a screen from side-angled views.

The campaign is based around a twist on the ‘I spy’ game and adverts that appeared as giant posters and on escalator panels at Bank, Liverpool Street and London Bridge stations stopped many commuters in their tracks. In addition, the ads were displayed in 400 train car panels across the Thames City Link network.

Said 3M marketing executive and product manager for the Display Materials and Systems Division, Georgie Winston-Bray: “We targeted commuters in our latest campaign as they often work on the go, leaving themselves open to the danger of prying eyes.

“The ads were designed to make people stop and think about the steps they can take to keep their confidential information private and invite them to visit the 3M Privacy website and order a free sample.”

Following the success of the campaign, the creative will be used as the centrepiece for a major social campaign targeting workers in different industries within a 50-mile radius of London.
