the random number we used in computer, can be accessed form some mathematical formula.

and i heard that the chaotic data is just similar with random noise.

if we just consider the data, one from compute, the other from some real process,can we distinguish it?


thx for every reply!:smile:

You should look into http://en.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator" [Broken].

The phase space of a chaotic system is relatively low dimensional, while the phase space of truly random noise would be infinite dimensional.

A practical algorithm to determine this is called False Nearest Neighbors.
