Look out for yourself
Complying with the PCI DSS is definitely one of the biggest concerns that many businesses have these days. The PCI DSS isn't perfect, but there's probably a good reason for its existence. Data breaches expose millions of credit card numbers each year, and many of these are used for fraudulent transactions. Consumers, however, typically don't end up paying for these fraudulent transactions, at least not directly. It's still there, though, because the cost of the fraud gets built in to the prices that we pay.
According to the Federal Trade Commission's 2006 Identity Theft Survey Report (the most recent version), the median out-of-pocket loss cost that consumers experience from all forms of identity theft is actually ZERO dollars. Instead, it's the merchants and banks who really end up absorbing the losses and paying fines when they lose credit card numbers. So if you're a merchant that accepts credit cards, you have a serious interest in reducing the number of data breaches that expose credit card numbers. If you're a consumer, you probably have better things to worry about.
If you're a consumer and your credit card number gets stolen, your bank will cancel the old card and issue you a new one. You may suffer a little inconvenience, but having your credit card number stolen probably won't affect you that much. You're probably better off worrying about other sensitive information that can't be just cancelled and replaced. This includes things like your credit history, your Social Security number and your medical history. If any of these gets compromised, it can't be cancelled and reissued. Once it's exposed, your privacy is gone for the rest of your life and it's probably impossible to get it back. If you're a consumer, you probably have more of an incentive to worry about the security and privacy of this type of information.
The PCI DSS has attracted most of the attention recently, but consumers really should be more concerned about the protection of information other than credit card numbers. If you're going to lobby your government to do something, look out for your interests. Let the banks and merchants worry about reducing credit card fraud. You should worry the most about the loss of sensitive information that affects you the most.
