Privacy: New Report Shows Increase in the Number of Trackers Collecting Online User Data

From the NY Times:

The number of trackers collecting data on users’ activities on the most popular Web sites in the United States has significantly increased in the last five months, according to research from the Berkeley Center for Law and Technology at the University of California, Berkeley.

The Berkeley project, called the “Web Privacy Census,” aims to measure online privacy by conducting periodic web crawls and comparing the number of cookies and other types of tracking technology found over time on the most visited sites.


On those 100 sites, researchers found 6,485 standard cookies last month compared with 5,795 cookies in May. In both months, third party trackers, not the Web sites themselves, set a majority of those cookies, the report said.

In October and May, cookies placed by DoubleClick, Google’s ad technology service, appeared on the most sites on the top 100 list. ScorecardResearch, an analytics unit of comScore, was the second-most-prevalent tracker, the researchers reported.
