As a report on Business Insider put it, if data-tracking poised a threat, and privacy a concern, credit-card companies know how much you earn, your phone number, what you bought, and how much of your cash you spent. In fact, in most places in the US, if you buy a house, not only is your address, but also details of how much you bought it for, and how much you sell it for are all points listed as public information.

The list can go on and on unless you have taken some extreme measures to protect your privacy, or if you don’t use any of these services at all.

As Faceook’s CEO Mark Zuckerberg said in an interview with TechCrunch, privacy is no longer a “social norm”.

So where does this lead?
