I think this is one plugin we won't see released by Google for Chrome anytime soon. A computer security researcher has launched a project designed to provide people greater privacy when using Google, as the company expands the scope of data its collects about its users.
The project, called GoogleSharing, is a Firefox add-on that uses an anonymous proxy service that gives Google false information when someone uses services that don't require an account, such as its search, news, and images services, said Moxie Marlinspike , a security consultant and penetration tester with the Institute of Disruptive Studies.

Google collects a vast amount of information about its users, said Marlinspike, who gave a presentation at last week's Black Hat conference. The company collects IP (Internet protocol) addresses, search requests, browser type and more.

Google as well as other major search companies have taken steps to allay concerns over data collection, such as anonymizing parts of IP addresses held in their records after certain periods of time. But Google dictates how it anonymizes information that could potentially be collated later to profile a user, Marlinspike said.

With IP addresses, for example, Google anonymizes the last octet of the address after nine months, Marlinspike said. Some privacy advocates argue that does not go far enough. Google also uses cookies, or data files stored by a browser, to associate search queries with a particular installation of a browser on a given computer.
