Adding random noise to a signal will not hide the signal

Or so I've been told by security experts.

A quick google search found this paper

Thanks for the comment Gregg.

Obviously they're talking about a very different problem, but I would agree with their assertion that obfuscation doesn't help if you still have a high signal-to-noise ratio. (They use a cutoff of one, which sounds reasonable to me.)

I would be interested in seeing applications to this specific problem if you have any? An SNR of 1 for browsing does not seem at all problematic here, but I don't want to read too much into that specific paper, as it wasn't really related.
