Halprin, Ran and Naor, Moni (2009): Games for extracting randomness. In: Proceedings of the 2009 Symposium on Usable Privacy and Security 2009. p. 12.

Randomness is a necessary ingredient in various computational tasks and especially in Cryptography, yet many existing mechanisms for obtaining randomness suffer from numerous problems. We suggest utilizing the behavior of humans while playing competitive games as an entropy source, in order to enhance the quality of the randomness in the system. This idea has two motivations: (i) results in experimental psychology indicate that humans are able to behave quite randomly when engaged in competitive games in which a mixed strategy is optimal, and (ii) people have an affection for games, and this leads to longer play yielding more entropy overall. While the resulting strings are not perfectly random, we show how to integrate such a game into a robust pseudo-random generator that enjoys backward and forward security. We construct a game suitable for randomness extraction, and test users playing patterns. The results show that in less than two minutes a human can generate 128 bits that are 2-64-close to random, even on a limited computer such as a PDA that might have no other entropy source. As proof of concept, we supply a complete working software for a robust PRG. It generates random sequences based solely on human game play, and thus does not depend on the Operating System or any external factor.
