Re: I robot
At least in the UK, the assumption is that if you are in a public place, ie walking down the street, then you have no expectation of privacy. So I have a Ring doorbell camera, it sees everything in my front garden and also the street outside, my front garden is my property and (within reason) can do whatever I want, and the street is a public space. On a private property, a shopping mall for example, then yes they are supposed to have a sign explaining that video recording is happening in here, and contact details for further information and (maybe) how to request copies of the recordings of yourself and your rights - something which absolutely nobody ever, ever bothers with.
In theory I could take a camera outside on the street and follow you around recording everything you do, unless you go into a shop, that’s a private, not a public area, I have no right to record you there. In practice I could be accused of harassment, but it would be up to a Court to decide.
Imagine this, I take a trip to Paris with my partner, and I take some video footage of her in front of the Eiffel Tower, but also happen to capture a number of Parisians in the background going about their lawful business? Could they legally demand that I delete the video?
Or have I missed the point? I’ve probably missed the point. But absolutely more than happy to have the legal situation explained to me.
