Methods for Random Number Tracking

what types of methods and algorithms are used to track random number generators? I'm working on computer security, and I want to know all the different ways to track random number generators so I know what to counter

What do you mean by "track" in this case? Keep track of what PRNGs are out there?

by "track" I mean predict what numbers will be generated by the RNG in advance.

The subject of random number generation and testing is reviewed extensively in Knuth's Seminumerical Algorithms.

thank you for the information, I actually own the first, third, and fourth volumes of "The Art of Computer Programming" however I never bought the second volume. I shall look into it. I have heard of the idea of generating random numbers using the uncertainty in the quantum mechanical laws of nature; however as far as the Computer Science community has published, it has not successfully been done in a way such that no pattern will emerge, so the HotBits is most likely very random, but not 100% untraceable.

Aim an alpha/beta radiation source at a camera and note where random pixels appear -- where does the computing bias arise in that?

Or more lately, reflect a coherent optical source back into itself and record the avalanche of noise that comes out. This one particularly can generate random numbers very very fast.

I did say that this was for a computer security project. I figured that it implied that everything was being done computationally, with no specific physical elements involved, so that it may work on any computer. So I was not considering anything involving a physical trigger. it is well known to me that radioactive decay is entirely random.
