Fingerprint required for library card

If you live in the nice little Chicago suburb of Naperville, Illinois, and want a library card, soon you’ll have to give up your fingerprint.

According to a Chicago Tribune article published last Friday, the city of Naperville is installing a fingerprint scanning system to control access to its computers. Unless your fingerprint matches the one on your library card, you won’t be able to use the so-called “public” computers in Naperville’s so-called “public” libraries.

The stored numeric data cannot be used to reconstruct a fingerprint, West said, nor can it be cross-referenced with other fingerprint databases such as those kept by the FBI or the Illinois State Police.

Uh huh. I really believe that. Just how gullible do you think I am?

Thanks again to security expert Bruce Schneier for the heads-up.

    Sure it can be. You may not be able to reconstruct the fingerprint from the numeric data, but you can compute the numeric data for the fingerprints stored at the FBI and then compare that numeric data against those from the library.
