'Cookies' Cause Bitter Backlash

Wall Street Journal


Tools that track users' whereabouts on the Web are facing increased regulatory and public scrutiny and prompting a flurry of legal challenges.

The tools cited in the suits are part of an "arms race" in tracking technologies, said Chris Hoofnagle, director of the Berkeley Center for Law & Technology's information-privacy programs. Some users, uncomfortable with tracking, now routinely block or delete cookies. "There are some in the industry who do not believe that users should be able to block tracking, so they are turning to increasingly sophisticated tools to track people," he said.
