According to Grubers analysis it compares the csam pictures against the library. Your 17 year old is not part of that database. Hence no hash matches.

CSAM provides a library with hashes that are compared against the photos on the phone.

The real problem comes when governments make laws that open the mechanism to different libraries of photos.

That's the CSAM part. The iMessages part uses a neural network to detect explicit photos through machine learning.

What happens when Apple, or the government, mandate an expansion of CSAM into detecting new material? Apple already has built a neural network to detect new explicit material...

Also, what happens when the USG mandates that Top Secret classified material must also be added to the database? Or when Russia mandates that homosexual pornography must be added to the database?

That doesn't appear to have happened in the 10+ years this kind of scanning has already been happening at various cloud providers - what specifically about Apple moving it down to the phone from iCloud Photos makes this more likely now?
