How Much Of Your Data Does Big Data Have?

As more institutions take advantage of improved tracking methods, all kinds of unusual information is being sold to data brokers, and there's still not a whole lot you can do about it.

What's the Latest Development?

As privacy advocates continue to push Congress to regulate data broker activity, writer Lois Beckett investigates in detail the types of personal data they gather, where they get that data from, and what they do with it. For example, while basic information such as age and gender is volunteered by individuals, a range of institutions from retail outlets to state motor vehicle departments sell additional data to brokers without the person's knowledge or consent. Most of this information is used for advertising, but some data is beginning to be evaluated for other purposes that may compromise individual privacy.

What's the Big Idea?

Most people know that their data is being collected at an ever-increasing rate, but what concerns advocates is how little control individuals have over its use. Data brokers have pushed back against attempts to increase transparency, and despite proposed legislative measures such as President Obama's Consumer Privacy Bill of Rights, Beckett says marketing-related data profiles in particular are unlikely to become available for inspection. Even if a profile is wrong, "the worst thing that could happen is that you get an advertising offer that isn't relevant to you," says Rachel Thomas of the Direct Marketing Association.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.

  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
