Many Europeans and Americans believe they should be mostly free of business and government snooping. But the laws are very different. U.S. privacy laws are narrower and address specific concerns, such as medical records. The sweeping E.U. Privacy Directive allows Europeans to protect their personal data from any industry that would like to exploit it. And each country has an independent, powerful privacy czar to enforce the laws. Peter Swire is chief advisor to the White House on privacy policy.

Swire: In Europe, privacy is seen as a human right. Your individual data is protected by human rights. In the United States, there's often the legal treatment of the data as it belongs to the company. If you do a transaction with the company, the company uses that information for its next transaction, it sells the information to who it wants to.

Say you subscribe to Sports Illustrated. The magazine can sell your name and everything it knows about you to a buyer of its choosing. In Europe, Sports Illustrated would have to notify its subscribers of its intentions, and customers have the right to opt out.

		Highlights of the EU directive: Any data that can be linked to a specific person is covered. Areas most likely to be affected are human resources, accounting, Web commerce, European database info, and auditing data. You can only use information for the original purpose for which it was collected unless you get the permission of the person or people involved. People must have notice that information about them is being collected and have the ability to object to its use. People must be allowed to correct erroneous information about them. You can't shelter information in "data havens," which are usually offshore places where data is collected and used in violation of stronger protections.

Reidenberg: In the United States today, citizens have very little protection against information trafficking, and it is occurring in both alarming and outrageous fashions. You can buy lists of people with particular medical ailments. I can buy lists of nursery school children organized by their parents' religions. I mean it's just astounding what kind of information is for sale in the United States, that citizens have no legal right to stop. That's not the situation in Europe because of their data privacy laws.

European privacy law in some ways is the flip side of that of the United States. American law offers more protection from government intrusion. For example, one law prevents government agencies from sharing personal data with each other. Americans tend to put more trust in how private interests use information, and favor giving companies a chance to regulate themselves.

The E.U. Directive places more trust in government, less in commerce. Europeans are likely to think the idea of industry self-regulation is laughable, that government has to keep it honest.

Why is European privacy law so different? For one, it reflects the E.U.'s penchant for sweeping, all-inclusive laws. Jane Kirtley, professor of journalism at the University of Minnesota and an expert on privacy issues says Europeans are less likely to worry about Big Brother.

Kirtley: It's the difference between being suspicious of government and believing that government is the answer to all ills, and frankly, my own view is that the American idea is to say, with a raised eyebrow, "Why do you want this power, government, and what is it that you intend to do with it?" And you're asking me to believe that. I'm skeptical about that.

Joel Reidenberg of Fordham University says the E.U. Directive is having an effect on this side of the Atlantic.

Reidenberg: The existence of the directive, I think, has had a major influence on the privacy debate in the U.S. It has woken up, in many ways, large U.S. companies that are operating globally to the need to have effective privacy protection.
