Google is being targeted in a class action suit that alleges it violates the privacy of its users by sharing personal information and Internet search queries of its users with third parties.
"User search queries, which often contain highly-sensitive and personally identifiable information, are routinely transferred to marketers, data brokers, and sold and resold to countless other third parties," the complaint said.
The suit was filed in a US District Court in San Jose, California, on Monday on behalf of a woman named Paloma Gaos, a resident of the San Francisco area, and other users of Google's popular search engine.
It seeks monetary damages and an injunction against Google ordering it to stop sharing search results with third parties.
"Because of its dominance in the search business, Google, more than any other company, presents a great risk to citizen privacy," said Kassra Nassiri, one of the attorneys bringing the suit.
A Google spokesman told AFP the Mountain View, California-based company had not yet received a copy of the complaint and "won't be able to comment until we've had a chance to review it."
Google denies transmitting personally identifiable information about users to third parties and says it "anonymizes" the results of Web queries, removing all traces of personally identifiable information.
