The solution is to use an already existing software product that solves this, like CloudFlare’s CSAM Detection. I know people on the fediverse hate big companies, but they’ve solved this problem already numerous times before. They’re the only ones allowed access to CSAM hashes, lemmy devs and platforms will never get access to the hashes (for good reason).
They will still need to have a developer set this up and presumably it should be added as an option to the main code base. I thought I heard the beehaw admins were not developers.
There are a number of other issues that are driving the admins to dump lemmy. Same applies there.
Not sure what you mean. You do not need to be a developer to set up CloudFlare’s CSAM detection. You simply have email the NCMEC, get an account, then check a box in CF, input some information about your NCMEC account, and then you’re good to go.
How does the scan happen? It has to be linked in some how. Are you saying that choosing cloudflair as your CDN that will flag at distribution time? Or at upload time?
If you use CloudFlare as your proxy then all your instances traffic gets routed through CF before ever making it to your server. If someone tries to upload CSAM it will immediately be flagged (before ever making it to your server). CloudFlare then quarantines it and automatically files a report with the National Center for Missing and Exploited Children. There’s more to the prices, but the point is that putting it in the lemmy software is not a good solution, especially when industry standard proven solutions already exist. You don’t have to use CF. You can also use solutions from Google, FB, Microsoft, Thorn, etc.
Interesting. Thanks.
Wait… why is no access to csam hashes a good thing? Wouldn’t it make it easier to detect if hashes were public?! I feel like I’m missing something here…
Giving access to CSAM hashes means anyone wanting to avoid detection simply has to check what they’re about to upload against the db. If it matches then they simply modify the image until it doesn’t. It’s literally guaranteed to make the problem worse, not better.
Ah thanks, hadn’t thought of that!
Question, from what I saw it seems like every CSAM image ever is assigned a new hash. Isnt it unscalable to asign a separate hash for everything? does that mean that most CSAM images were detected before?
