> and they want to check if any of the hashes are the same as hashes of child porn?
... without any technical guarantee or auditability that any of the hashes they're alerting on are actually of child porn.
How much would you bet against law enforcement to abuse their ability to use this, and add hashes to find out who's got anti government memes or police committing murder images on their phones?
And that's just in "there land of the free", how much worst will the abuse of this be in countries who, say, bonesaw journalists to pieces while they are alive?
I remember the story where some large gaming company permanently banned someone because they had a file with a hash that matched a "hacking tool". Turns out the hash was for an empty file.
This will end badly for humanity.
Path of Exile has in the past looked at DNS cache information on the system and will ban players who have contacted known bad sites.
they don't check the unhashed bytes against the child porn bytes after a hash match?
