reading it carefully it could be read that passengers can request not being recorded.
meaning automatic recording but deletion if a reqeust is formally made
this means that data gathered would require a person then asking for it not to be kept.
if regulations become wordd as such i can see this being abused in many ways like making it so annoying to say no to face recog (like how annoying it is to say no to cookie/ad/data tracking on every website) that people end up just pushing accept rather than deselecting 50 tickboxes
a bit like how stupid browsers work that send a 'do not track' request. or them phone call services that suppose to stop business cold calling you...
yet you then find out data is still gathered, info is still passed around and then if found out years later they just say 'oopsie sorry, tell use the cost of the fine and we will pay it.. no harm done'
you know. the whole 'teenager has criminal records sealed and expunged at 18' .. yet years later gets told someone unsealed the records..
or them anonymous adoptions where social services still have the records but just say they cant disclose
hmmm... not quite a removal of record after all if someone was able to find it
only solution
have no cameras at airport check-in desk at all. or if there is a camera make it abundantly clear you dont want records kept, but still expect someone somewhere to still have that data
