Why is it worrying?
If you have nothing to hide, then you have nothing to hide.
See my signature "it's not that i have something to hide, it's that I have nothing for you to see".
nothing to hide doesn't automatically give or provide consent to enter or access.
Just cause I did NOT say the word 'No' doesn't automatically mean I've provided the word 'Yes'.
Because it’s a violation of personal privacy and it sets a dangerous precedent for the future. Today we let Apple scan our photos and tomorrow what?
It’s funny, years ago Apple was firmly standing against the US Government asking for a back door into a locked iPhone but today they’re proposing passive surveillance of individuals’ photo libraries.
I’m all for the identification and prosecution of people breaking laws but the whole “if you have nothing to hide don’t worry about it” argument is so dismissal of such a fundamental right.
I'm highlighting in BOLD for specific affect of rebuttal.
1. source of those pictures - if taken from public domain (source of the picture itself, not the subject) then it's not personal privacy. Example if you saved a picture or screenshot if a picture from the internet it's already public and not personal privacy. The real specifics in courts of law I'm not aware of, so I could be wrong but likely in this specific mention I doubt it's personal privacy protections.
2. If a law allows for searching device, or cloud storage ... then its likely not a breach of personal privacy.
More importantly you'd need to think where are you storing your pictures and what content OF those pictures has you thinking it's personal privacy.
Like a) nudes of children. If not your children or children you've adopted and simple clothing or baby pictures (I'm still feeling the tradition of taken family photos of nude babies is creepy period, but that's just me) or nude pictures of your kids whom have had a rash or mark or health concern forwarded to health care practitioners ... then that's on you/them/they.
The example of your kids with health issues sent to health care practitioners is something that not too recently occurred since a father at home noticed his child had a strange protrusion in the grown of his child and took a picture and sent to the doctors is now in legal hot water. Name is public and lost his job without even an explanation. not sure how that turned out though.
That is where this situation can go wrong! photo he used or OS or cloud service I don't know/cannot recall for the life of me. In such a case I wonder if Apple's implementation if a parent would get flagged in this scenario?!
