Is privacy possible in a social network? And, if so, which social-network service does it the best? We put Facebook and LinkedIn head-to-head.

Social networks have come in for a lot of criticism over their approaches to privacy, whether it's Facebook, Google Buzz or even the more business-orientated LinkedIn.

So is privacy possible in a social network? And, if so, which social-network service does it the best?

To answer this question, this month I donned my privacy goggles and pored over the two social networks that my professional peers seem to use the most: Facebook and LinkedIn.

I also asked all my Facebook friends and LinkedIn connections to tell me which they thought did privacy better. (I didn't look at Buzz because I admittedly don't know anyone using it.) What did I find out?

Privacy certification: A draw

One way to easily determine whether a website takes privacy seriously is to check for a privacy seal.

In North America, the two worthwhile options are Truste and WebTrust, while the German-based EuroPriSe seal is a nascent arrival in Europe.

With all of suchtrust marks, a website generally pays a fee to have its privacy practices independently certified.

As it turns out, both Facebook and LinkedIn have earned the Truste EU Safe Harbor seal.

This means they both officially made Truste their arbiter for consumer disputes over European privacy compliance.

Indeed, both companies have self-certified to the EU-US Safe Harbor agreement that the Department of Commerce administers and the Federal Trade Commission enforces.

(You can find the Facebook certification here and the LinkedIn submission here.)

By taking this step, both companies have committed themselves to adhering to seven European privacy principles.

Moreover, the privacy officers putting their names on the Safe Harbor submissions have personally attested, under penalty of the federal False Statements Act, that their submission is truthful.

I've clicked that False Statements button before, and I can tell you it causes you to make sure a strong privacy program is backing you up.

So far, the comparison on this point is a draw.
