While computer systems can be quite susceptible to deception by attackers, deception by defenders has increasingly been investigated in recent years. Military history has classic examples of defensive deceptions, but not all tactics and strategies have analogies in cyberspace. Honeypots are the most important example today; they are decoy computer systems designed to encourage attacks to collec...

The ethics of placebo research have been of paramount concern since the discovery of the phenomenon. To address these ethical concerns, Miller and colleagues (PLoS Med 2005 Sep;2(9):e262, 0853-0859) propose an alternate approach to placebo research, called "authorized deception", in which participants are alerted of the use of deception in the research prior to study enrollment and thus knowing...

This paper addresses the task of detecting identity deception in language. Using a novel identity deception dataset, consisting of real and portrayed identities from 600 individuals, we show that we can build accurate identity detectors targeting both age and gender, with accuracies of up to 88%. We also perform an analysis of the linguistic patterns used in identity deception, which lead to in...

We develop a process model that explains the escalation of deception in corrupt organizations. If undetected, an initial lie can begin a process whereby the ease, severity and pervasiveness of deception increases overtime so that it eventually becomes an organization level phenomenon. We propose that organizational complexity has an amplifying effect. A feedback loop between organization level ...

Much robotics research explores how robots can clearly communicate true information. Here, we focus on the counterpart: communicating false information, or hiding information altogether – in one word, deception. Robot deception is useful in conveying intentionality, and in making games against the robot more engaging. We study robot deception in goal-directed motion, in which the robot is conce...

This chapter provides an overview of techniques and tools to detect deception on the Internet. A classification of state-of-the-art hypothesis testing and data mining based deception detection methods are presented. A psycho-linguistics based statistical model for deception detection is also described in detail. Passive and active methods for detecting deception at the application and network l...

Deception plays a critical role in the financial industry, online markets, national defense, and countless other areas. Understanding and harnessing deception especially in cyberspace is both crucial and difficult. Recent work in this area has used game theory to study the roles of incentives and rational behavior. Building upon this work, we employ a game-theoretic model for the purpose of mec...

Deception has long been an important topic in philosophy (see Augustine 1952; Kant 1996; Chisholm & Feehan 1977; Mahon 2007; Carson 2010). However, the traditional analysis of the concept, which requires that a deceiver intentionally cause her victim to have a false belief, rules out the possibility of much deception in the animal kingdom. Cognitively unsophisticated species, such as fireflies ...
