Apple's CSAM Detection with Matthew Green

We're talking about Apple's new proposed client-side CSAM detection system. We weren't sure if we were going to cover this, and then we realized that not all of us have been paying super close attention to what the hell this thing is, and have a lot of questions about it. So we're talking about it, with our special guest Professor Matthew Green.

We cover how Apple's system works, what it does (and doesn't), where we have unanswered questions, and where some of the gaps are.
