"In the coming weeks, users will be allowing Apple to comb through a portable computer containing private messages, photos, videos, banking information, and business records; all without anyone being able to verify what it is looking for, or with whom it is sharing that information." Does anyone know if security researchers will be able to figure out this kind of information? Are the hashes known, for example? So would non-CSAM hashes be detectable? Seems like people could, in principle, load various non-illegal images and video onto an iPhone and see what, if anything, is reported - the phone must send some information at some point so traffic analysis should reveal it.
