In the era of Big Data, the fight for protection has as of now been battled and lost. The personal data is routinely gathered and exchanged and there are few powerful controls over how it is utilized or secured. Data scientists and analysts are now saying that now is the right time for enactment to recover some of that protection and guarantee that any information that is gathered remains secure.

We have become the product and are being productised and sold to anyone. We’re being monetised and mobilized as products with inducement of the services of we use such as Facebook and Twitter. The dilemma that the regulators are facing is how they can regulate the collection, storage and trading of personal data on the on the internet, when all of these activities, and the corporations themselves, operate across multiple continents and jurisdictions.

The task of reclaiming some semblance of privacy is all the more urgent because the rate at which personal data is being collected is accelerating.

A bill that would make it illegal to hide security problems was set to pass into law last year, however it failed to make it through both houses of the Senate before the election. And since the Coalition took power, the legislation has stalled. 

Still, there are many privacy challenges ahead, and the problems have by no means been solved. Most methods of anonymizing do not scale well as p or n get large. Either they add so much noise that new analyses become nearly impossible or they weaken the privacy guarantee. Network-like data pose a special challenge for privacy because so much of the information has to do with relationships between individuals. In summary, there appears to be “no free lunch” in the trade-off between privacy and information. To read more: http://www.theguardian.com/technology/2014/jun/20/little-privacy-in-the-age-of-big-data
