Reply to comment by Mindless_Consumer in A group of researchers has achieved a breakthrough in secure communications by developing an algorithm that conceals sensitive information so effectively that it is impossible to detect that anything has been hidden by thebelsnickle1991

That's not what they're claiming though. The presence of a signal is known. The presence of a second message embedded in the signal is what is undetectable because the encoding process is embedded in probabilistic filters that the signal was subjected to anyway. And the output signal is indistinguishable from a signal that went through such a filter with no embedded message.

Yea. So match the signal to that of a local star or some other natural phenomenon.

The point is - if this is impossible which it may be. Long communication in a hostile galaxy may be impossible. If it is possible an explanation for not detecting signals is they are hidden and undetectable.

I love that you went right to space travel. I don't think this is applicable but I like where your mind is at

Yea, like, I thought we were on futurology.

Like I said - its a big deal.

If it is actually hard undetectable, this is how we're going to do it. That's pretty cool.
