Researchers at U.C. Berkeley have discovered that some of the net’s most popular sites are using a tracking service that can’t be evaded — even when users block cookies, turn off storage in Flash, or use browsers’ “incognito” functions.
The service, called KISSmetrics, is used by sites to track the number of visitors, what the visitors do on the site, and where they come to the site from — and the company says it does a more comprehensive job than its competitors such as Google Analytics.
But the researchers say the site is using sneaky techniques to prevent users from opting out of being tracked on popular sites, including the TV streaming site Hulu.com.
he research was published Friday by a team UC Berkeley privacy researchers that includes veteran privacy lawyer Chris Hoofnagle and noted privacy researcher Ashkan Soltani.
