Comment on Stop children using VPNs to watch porn, ministers told

There is actually a technique called steganography, that does exactly that. It is used to hide arbitrary binary info inside images, while still fooling your eyes into thinking there is nothing sketchy there.

I know! Nothing about all this is new.

The only new thing is that the UK government ist about to learn about those things.

Doesn’t jpg break this? And can’t it be detected? I imagine AI could be used to some extent.

  I didn’t say that it can’t be detected. I said it fools your eyes.
  
  Besides that, stop using ML for everything. My guess is that you need insane amounts of processing power for ML to detect hidden messages inside terabytes of live internet traffic.
  
  In fact, the algorithm for steganography is standard. It’s probably trivial to detect it, unless you add encryption and padding to the mix.

    “Stop using ML for everything”
    
    I see no other way to drink from the firehose. We’re talking nationstate level resources.
