Ouchhh:
'If the software changed, and you COULD recreate a fingerprint from this library procedure, would it still be ok?'
No. That's why I've said it bears watching, but my layperson's understanding is that the process - so it's not to do with the software, as there's perfectly adequate software on my home PC to produce high res scans of the whole town's fingerprints -is that you can't reverse engineer from a 9 or 12 digit ID number to an image of someone's fingerprint.
'If the libraries were to require a full set of inked fingerprints from your DCs to take out a book, would you agree happily to that?'
No. Why would they want to, anyway, if a computer-generated number from one fingerprint is sufficient to identify a student in a high school population of 1000 or so?
'What about eye scanning, if they had that, instead of finger scanning? Would that be OK? After all, why is eye scanning any different to finger scanning?'
Well, if it's a means of generating a number, it isn't any different. Fingers are probably easier though.
Look, I agree it's something that needs monitoring.
But in practical terms, I teach in a school of 800, & I could put a name probably to 500 faces. So could the school librarian, but if our Head wasn't too tight to pay for this system, it might speed things up a bit for her...
It's a bit of a toy at present, & I think it's part of a much bigger potential picture. Hmm.
Still wouldn't go gunning for the TA personally, though. I'd be tackling the governors about whether a) they should be introducing such a system & b) how they think 'opt-outs' should be protected from internal cock ups as in the OP.
