Web Firms to Adopt 'No Track' Button

A coalition of Internet giants including Google has agreed to support a do-not-track button to be embedded in most Web browsers—a move that the industry had been resisting for more than a year.

The reversal is being announced as part of the White House's call for Congress to pass a "privacy bill of rights," that will give people greater control over the personal data collected about them. The new do-not-track button isn't going to stop all Web tracking. The companies have agreed to stop using the data about people's Web browsing habits to customize ads, and have agreed not to use the data for employment, credit, health-care or insurance purposes. But the data can still be used for some purposes such as "market research" and "product development" and can still be obtained by law enforcement officers. The do-not-track button also wouldn't block companies such as Facebook Inc. from tracking their members through "Like" buttons and other functions.
