title = "Security design in human computation games",
abstract = "We consider a binary labelling problem: for some machine learning applications, two types of distinct objects are required to be labeled respectively, before a classifier can be trained. We show that the famous ESP game and variants would not work well on this binary labelling problem. We discuss how to design a new human computation game to solve this problem. It turns out that interesting but subtle security issues emerge in the new game. We introduce novel gaming mechanisms, such as {\textquoteleft}guess disagreement{\textquoteright}, which improve the game{\textquoteright}s security, usability and productivity simultaneously.",
