This. Technically the iphone can process images locally. Photos app shows what is in the picture (faces, pets, food) and can do ocr on text in screenshots and photos. This is a very real possibility to outsource the processing to your device.
The camera itself does software processing and you can't encrypt the light. It detects faces even before you click the shutter for capture. There is no way to keep the device itself from ever knowing what it was looking at. Something that sensitive is something you don't photograph.
we agree I believe. I am saying that technically the device gets thst information on-device, and could send it. Idk if that is the case, but it is possible.
Edit:The ocr and face recognition on the iphone is definitely more advanced than usual, thanks to the custom hardware on device.
