LifeLock's founder Todd Davis was famous for his advertisements where he shows his social security number and dares identity thieves. According to a lawsuit filed against the privacy protection company, that strategy may have failed him.

SAN JOSE, Calif.
--

Todd Davis has dared criminals for two years to try stealing his identity: Ads for his fraud-prevention company, LifeLock, even offer his Social Security number next to his smiling mug.

Now, Lifelock customers in Maryland, New Jersey and West Virginia are suing Davis, claiming his service didn't work as promised and he knew it wouldn't, because the service had failed even him.

Attorney David Paris said he found records of other people applying for or receiving driver's licenses at least 20 times using Davis' Social Security number, though some of the applications may have been rejected because data in them didn't match what the Social Security Administration had on file.

Davis acknowledged in an interview with The Associated Press that his stunt has led to at least 87 instances in which people have tried to steal his identity, and one succeeded: a guy in Texas who duped an online payday loan operation last year into giving him $500 using Davis' Social Security number.

Paris said the fact Davis' records were compromised at all supports the claim that Tempe, Ariz.-based LifeLock doesn't provide the comprehensive protection its advertisements say it does.

"It's further evidence of the ineffectiveness of the services that LifeLock advertises," said Paris, who is lead attorney on the three new lawsuits, the latest of which was filed this month.

Davis learned about the fraud in Texas when the payday-loan outfit called to collect on the loan, he said. He didn't get an alert beforehand because the company didn't go through one of the three major credit bureaus before approving the transaction.
