There is some new information in this interview, notably that Craig actually gives a rough number to the amount of positive hashes required to flag them for review on iCloud is approximately 30 images. I don't think this had been mentioned previously and it's not something I think people creating this sort of system would normally want to share publically, given that understanding the system in place is the first step in bypassing it. The other thing he mentions is that there are auditable systems in place, at least by security researchers. He doesn't really disclose how it is, just that there are ways for a third party to investigate any changes to the system and any sort of tampering to the hash database. He also firmly denies that he considers this technology a backdoor. But once again another Apple executive is saying that the primary reason for the backlash is confusion or lack of understanding of the technology, which, while there is a lot of uninformed people on the subject, fails to acknowledge that there are people that do understand the technology and still have objections to it.
