What technology are you referring to as already deployed?
- floatingatoll 5y agoFor macOS, I'm talking about XProtect and MRT. I don't know the exact subsystem names on iOS, apologies. https://support.apple.com/guide/security/protecting-against-malware-sec469d47bd8/web https://support.apple.com/guide/security/protecting-against-... Each system is closed source, provides a mechanism for checking content signatures against files on disk, and is thought to report telemetry to Apple when signatures are found. How is CSAM scanning new and different from those existing closed-source systems?
- neolog 5y agoI'd say the primary differences are that the CSAM scan is a perceptual hash rather than a regular file hash, and that the technical infrastructure of the CSAM system is designed from the ground up to be used against (rather than for) the user and report them individually to authorities for violation.
- floatingatoll 5y agoDo you have an alternate design in mind that is both "used for the user", and is also effective at reporting CSAM content being uploaded from the device, without allowing CSAM abusers to opt-out of that reporting? I haven't been able to come up with anything myself, but maybe you've had better luck.
