Where would you get the CSAM hashes?
- dannyw 5y agoGive it a few days, and you'll probably find someone selling a list of CSAM neural hashes on darknet marketplaces.
- Dylan16807 5y agoOr tweeting out a bunch of them. They're just 12 byte numbers.
- copperx 5y agoI bet there's a list of hashes already up in Pastebin.
- arsome 5y agoThe client has to be able to check for them in some way - just run that algorithm against every image you can scrape from Tor/Freenet and I suspect you'll have results rather quickly. Or you can probably just wait a minute and pay an... enterprising individual to sell you such a list on a darknet market though, or perhaps even find one posted on the clearnet soon enough.
- robertoandred 5y agoNo, the client doesn’t have access to the CSAM hashes. And matches are verified on the server, not on the client.
- belltaco 5y agoThe poster meant the algorithm to compute the hash has to be on the local device. And it's already been found. https://old.reddit.com/r/MachineLearning/comments/p6hsoh/p_appleneuralhash2onnx_reverseengineered_apple/ https://old.reddit.com/r/MachineLearning/comments/p6hsoh/p_a...
- arsome 5y agoIndeed, if they're proposing to only decrypt select images the client needs to know pass/fail at some point. Whether that's before or after sending the hashes to Apple's server really doesn't matter as bulk checks will likely be a part of API anyways. We'll have to wait for further reverse engineering to get full details here though.
