Trinity college researchers have developed a new app to help let people know just how much they are revealing about themselves on social media, highlighting your likes, comments and preferences across multiple platforms.

Called Big Foot, it retrieves your social media activity across Twitter, Facebook and Instagram, combining it into visualisation that shows just how marketing companies may be able to work you out.

After logging in to your three accounts, readings on how positive your comments are, or what types of music or films you are into, combine to show a suite of general predictions from your online persona.

Considering the data you input into social media is used to shape how that service markets your profile, it can prove quite revealing to users when they see just how leading their comments or likes can be.

There’s also a questionnaire asking users how much they value their personal information, even suggesting a price with which to sell it to social media companies.
