I see where you’re coming from and will do my best to clarify my position. I am going to distinguish between Explicit and Tacit consent, and Explicit and Assumed Knowledge. The reason I distinguish between Explicit Knowledge and Explicit Consent is that you can combine them in different ways:
Yes Explicit Knowledge Yes Explicit Consent (interview)
Yes Explicit Knowledge No Explicit Consent (bike thief being filmed)
No Explicit Knowledge No Explicit Consent (Covert filming)
In order to give Explicit Consent to being filmed you must first have Knowledge of being filmed. This might be someone who agrees to be interviewed on camera.
The bike thief didn’t give Explicit Consent to be filmed, but did have Knowledge of being filmed. If they didn’t want to be filmed they could do something about it, such as leave the area, or confront the person filming. Because they didn’t take action to prevent themselves from being filmed despite knowing that it was happening, they gave Tacit Consent.
You say that by this measure:
Someone could stick a camera in your face and follow you around
No, that’s called harassment and is a separate offence.
The woman being covertly filmed doesn’t have the Explicit Knowledge that she is being filmed and so cannot give Explicit Consent. She is also unable to take any specific action against being recorded because she unaware that it is happening: the filming is covert. (You misread my previous comment, I was saying she could have done something if she had known).
Here’s the catch: this is all happening in public, and there is no expectation of privacy in public. This is where Assumed Knowledge comes in. When you are in public you must Assume that you may be recorded. It may be by someone taking a selfie, or filming ducks in the park, you may never see them. This isn’t Covert, because you Know it may be happening (and if you see people filming or taking photos you can then deny Tacit Consent by not walking into their photo).






None of what is considered ‘AI’ is actually AI, it’s just a rebrand of machine learning tech that has been around for a few years now (and is genuinely useful in certain circumstances). It’s all ‘AI’, only the generative AI is worth getting mad about.
