As much as I hate child abuse (and I really do) I don't like the privacy aspects of this. I feel like this could also be troubling in that people who send you unsolicited images / emails / texts with pictures that might be downloaded to your device could trip this up. I'm already wondering how a hash collision attack could defeat this, although then I can already hear the judge saying "well, you had it there, but you deleted it, so now we'll also charge you with destruction of evidence." This is going to get very interesting very quick as soon as this is first used in case law.
