Big Data and a Renewed Debate Over Privacy

NY Times reports about a paper, “Unlocking the Value of Personal Data: From Collection to Usage”, suggesting stricter control over usage of data:

The forum report suggests a future in which all collected data would be tagged with software code that included an individual’s preferences for how his or her data is used. All uses of data would have to be registered, and there would be penalties for violators.

I already like it. A lot.

Someone Is Monetizing Big Data and It Is Not for Our Benefit

Similarly some of the banks have admitted that they will be mining data related to the transactions we perform to understand our buying behavior. This data can then be sold to retailers or e-marketers to generate specific offers that may suit our lifestyle. It may be creepy to get an e-coupon out of the blue on your birthday (or anniversary) from a retailer that you would have shopped with some time back, but it could also have some nice benefits. On top of that, each one of us leaves behind digital tracks when we search or browse through different sites looking for something on the internet. If such data can be tagged to us, it can demonstrate our common interests.

Call me a privacy freak, but I find this unacceptable. And I have a very hard time understanding what’s in it for us[1].

  1. That’s the mildest form to say that I cannot really imagine any benefits for us.

What are the major issues surrounding data ownership?

Jeff Jonas (IBM):

The truth about data is that once it is out there, it’s hard to control.

It feel great to read such a confirmation about about BigData ownership and privacy concerns from high profile people.

Big Data Marketplaces and Data Privacy

To clarify: our goal was to map the nodes in the training dataset to the real identities in the social network that was used to create the data. […]

We were able to deanonymize about 80% of the nodes, including the vast majority of the high-degree nodes (both in- and out-degree.) We’re not sure what the overall error rate is, but for the high-degree nodes it is essentially zero.

We can go back to my questions: who will decide, regulate, and guarantee the level of privacy for data sets traded on the big data market?
