for example, can FB provide a list of recording locations and times, so I can request my image/audio removed?
How good is facebook's anonymisation system? what % of faces can be removed (on average)
Has every single piece of footage captured with Aria been anonymised?
"Participants will only record in either Facebook offices (once they reopen), wearers’ private homes (with consent from all members of the household), or public spaces, and won’t record in private venues without written consent from such places. Before any information gathered in a public place is made available to our researchers, it will be automatically scrubbed to blur faces and vehicle license plates."
So we anonymize all the content collected in public. I don't have the stats for the face blurring algorithm, and while you can ask for your data to be removed, we don't provide locations/times. These are good suggestions though.
I see some contradiction here.
You don't know "the stats for the face blurring algorithm" but you're saying you "anonymize all the content collected"?
If the stats don't say it's 100% (which is impossible afaik if done by machines) you obviously don't anonymize upfront all the content collected.
