New York, January 22

It does not matter if you are on Facebook or not - or have just deleted your social media presence. Your friends are constantly leaking your privacy to others, reveals a significant study.

The researchers from the University of Vermont in the US and University of Adelaide in Australia found that if a person leaves a social media platform -- or never joined -- the online posts and words of their friends still provide about 95 per cent of the "potential predictive accuracy", of a person's future activities -- even without any of that person's data.

"Privacy on social media is like second-hand smoke. It's controlled by the people around you," the researchers said in a paper published in the journal Nature Human Behaviour.

To reach this conclusion, the team of scientists gathered more than 30 million public posts on Twitter from 13,905 users.

With this data, they showed that information within the Twitter messages from eight or nine of a person's contacts make it possible to predict that person's later tweets as accurately as if they were looking directly at that person's own Twitter feed.

When you sign up for Facebook or another social media platform, "you think you're giving up your information, but you're giving up your friends' information too," said mathematician James Bagrow from the University of Vermont who led the research.

The research raises profound questions about the fundamental nature of privacy -- and how, in a highly networked society, a person's choices and identity are embedded in that network.

The findings showed that, at least in theory, a company, government or other actor can accurately profile a person - like political affiliation, favourite products, religious commitments -- from their friends, even if they've never been on social media or delete their account.

"There's no place to hide in a social network," said study co-author Lewis Mitchell.

How information moves on social media platforms, like Facebook and Twitter, has become a powerful factor in protest movements, national elections, and the rise and fall of commercial brands.

"Along the way, people on these platforms reveal massive amounts of information about themselves -- and their friends," said the researchers.

"You alone don't control your privacy on social media platforms," says professor Jim Bagrow from University of Vermont. "Your friends have a say too." IANS

    Breaking stereotypes from within

    Almost all Punjabis in the US have these things in common: they’ll probably be in the restaurant business (either as owners or chefs); they usually stick together and you can never take Punjab out of their heart. These typical traits of this inclusive community are bound to generate stereotypes about them.
