If some person was able to pick me out from a lineup because they physically saw me then that wasn't private and privacy laws don't apply.
So for instance capturing my face on CCTV in a public place isn't a privacy violation, same with my license plate in a pulic place.
However what happens on my private property is a privacy violation if it is recorded without consent.
Certian information isn't private, and that being stored is fine. Where the line gets drawn is what's up for debate.
I surely would want my contact details and name saved by a company that I intend to do business with in either direction. However if they spam me with information I should be able to lodge an harrassment claim against them. It's not a privacy issue but a decency issue.
