Sure, it seems as if old, crufty bits sit on the 'Net just waiting to embarass us ("oh, yeah, maybe I *did* post to alt.naughty.stuff 'way back then...") but there *is* such a thing as bit rot and perhaps it really is our friend after all. The first question, always, when evaluating security measures is to ask "What are you trying to protect?" This gets really weird when you don't know what the threats really are, which is true of this situation. I don't really see "privacy" itself as something you can pursue as an absolute objective. I think Black Unicorn's tale illustrates this well -- he doesn't try for non-existence, instead he describes a series of well reasoned and consistent steps. Basically, though, it has to be a personal choice. So it's hard to judge perfectly for another, even your own kids. IMHO you have to find a reasonable balance for your kids. The problem is that you don't want your kids to disappear -- there are times they will WANT their records found. The problem is to make verification easy when they're directly involved and difficult otherwise. The basic and obvious rule to most of us is to control the SSN and don't give out a correct one except when absolutely necessary. One of the banks in Minneapolis refuses to pay interest at all if you don't have your SSN on file. I toyed with the idea of manipulating birthdates, but it wasn't clear what the benefit was. Also, it required my wife's help, and I'll defer to Tim May's recent discussion of his'n'her anarchy if you wonder why this might be an impediment. If the kids know their "real" birthdate they'll *always* report it to their teachers. And if it's consistently incorrect in school records, then what does it mean for it to be different? When faced with peculiar situations I try to choose a disclosure that meets whatever the immediate requirements are but doesn't make it easy to automatically match up records. Often the best you can do is reduce certainty and increase the likelihood of multiple matches with other records. It doesn't hurt if you last name is Smith here in the U.S.A. Rick. smith@sctc.com
