5. Making a profit on your paranoia is obnoxious

What you're getting access to is, after all, data about yourself as reported by your creditors. I'd argue that you should be able to access that data for free at least once a month, rather than just once a year. I also think we should have free access to our FICO scores. The idea that these services would lure you into paying hundreds of dollars for those numbers, particularly by fanning your fears of identity theft, really reeks.

Here are the latest facts about identity theft, according to Javelin Research, which conducts an annual survey on this problem:

  • 3.6% of Americans were victims of identity theft last year.
  • 1.1% were victims of new-account fraud, the most expensive kind in terms of the total amount stolen. (The rest were typically victims of existing-account fraud, including credit card fraud and other takeovers of existing accounts.)
  • The typical amount paid out of pocket by victims: $0.

For most people, dealing with credit card fraud or an account takeover is as simple as reporting it to the creditor. The bogus charges are erased, a new account number is issued, and life goes on.

New-account fraud is a much bigger pain in the behind. Even though the typical victim doesn't pay out of pocket, he or she spends a median 25 hours resolving the fraud.

That's no small thing. But if you're really concerned about reducing your risk, you should consider some other, typically lower-cost and often more effective options before you opt for credit monitoring. Among them:

Lock down your data. You know the drill: Don't carry your Social Security card, and be wary about giving out the number. Keep your financial information and tax files in a secured, locked location. Shred sensitive documents. Raise your privacy settings, and limit what you post on social-networking sites. Posting information such as your date of birth, a pet's name and your mother's maiden name are particularly stupid, since those are often used in the challenge questions banks employ to confirm your identity.

Monitor your accounts. Review every single transaction of every single bank and credit card account. Log on to dormant accounts occasionally to make sure they haven't been activated by a bad guy. Use your free access to your credit reports at AnnualCreditReport.com, perhaps on a rotating system so you're looking at a different report every four months. And for heaven's sake, pay attention if you get a notice that your personal or financial information has been compromised. If the stolen data included your Social Security number, you need to go on high alert.

Consider security freezes. Also known as credit report freezes, these locks allow you to essentially shut off access to your credit reports. If someone applies for credit in your name and the lender checks your credit reports, it won't be able to see your data -- and likely won't approve the application. Security freezes are the best defense individuals have against new-account fraud, but they aren't necessarily cheap or hassle-free. If you're already a victim of identity theft, with a police report to prove it, you may be able to get freezes for free in your state. Otherwise, you typically have to pay fees of $10 to $15 to each credit bureau to freeze your reports, as well as fees to temporarily thaw them when you want to apply for credit.

Because of the fees involved, some experts have recommended putting free "fraud alerts" on your credit reports instead. That signals to lenders that you may have been the victim of an identity theft attempt, and that the lenders should take extra steps to make sure whoever is applying for credit is really you. But alerts typically last only 90 days and can be extended only if you have a police report or an affidavit showing you've been a victim.

If you are at high risk of new-account identity theft -- you've already been a victim or you've been informed that your Social Security number has been compromised -- you might sleep better at night with a credit-monitoring service. But in my view, that money would be better spent on security freezes. Better to lock the barn door than just set an alarm.
