Privacy organisations have spoken out against Google's recent move to add public data on the social network Google Plus to its search engine results page.

The search giant announced this move earlier this week, giving it the hacky sounding name of, "Search plus your world."

The Register reports that the Electronic Privacy Information Centre has spoken out against this move and is set to make a complaint to the US Federal Trade Commission, claiming an infringement of personal privacy.

"Although data from a user's Google+ contacts is not displayed publicly, Google's changes make the personal data of users more accessible," EPIC noted on its website. "Users can opt out of seeing personalized search results, but cannot opt out of having their information found through Google search."

While Google became the main face of the internet and the default home page for most users over the past couple of decades, in recent years, Facebook has begun to eclipse the one time dominance of the firm. With the big push into social networking, Google is hoping to mimic and mitigate the trend setting Mr Zuckerburg's venture has created. All it needs at this point is for Facebook to launch its own internal search engine - something that wouldn't be hugely surprising in this increasingly competitive atmosphere.

Facebook is often quoted as having 800 million users at this point, though it's unknown how many of these are active. Google Plus on the other hand recently eclipsed the 50 million mark. This is impressive considering even at its peak, Myspace only garnered some 100 million, but it's still a ways off directly competing with Facebook's pole position.
