Big Data age puts privacy in question as information becomes currency

By Aleks Krotoski  /  The Guardian, LONDON

The second decade of the 21st century is epitomized by Big Data. From the status updates, friendship connections and preferences on Facebook and Twitter to search strings on Google, locations on mobile phones and shopping history on store cards, this is data that’s too big to compute easily, yet is so rich it is being used by institutions in the public and private sectors to identify what people want before they are even aware they want it.

Facebook’s projected US$100 billion value is based on the data it offers people who want to exploit its social graph. It has more than 800 million records about who’s in a user’s social circle, relationship information, likes, dislikes, public and private messages and even physiological characteristics.

“People give out their data often without thinking about it,” European Commission Vice President Viviane Reding said. “They have no idea that it will be sold to third parties.”

She has campaigned for the “right to be forgotten” — a 1995 directive that establishes that private data is the property of the individual and must be deleted on request at any time.

“More and more people feel uncomfortable about being traced everywhere,” Reding said.
