Unfortunately, the data that was stolen in the breaches I was involved with may hound me for the rest of my life. Things like my Social Security Number, my Date of Birth and my Driver's License Number aren't going to change. They'll have value to those who stole my data for the rest of my life and possibly even thereafter. Having said that, your approach may be the only one to take for folks who want to be able to sleep at night. Whether or not it proves to be sufficient in the long run remains to be seen.
