Abstract While individual differences in decision-making have been examined within the social sciences for several decades, this research has only recently begun to be applied by computer scientists to examine privacy and security attitudes (and ultimately behaviors). Specifically, several researchers have shown how different online privacy decisions are correlated with the “Big Five” personality traits. […]

Abstract Despite the plethora of security advice and online education materials offered to end-users, there exists no standard measurement tool for end-user security behaviors.  We present the creation of such a tool.  We surveyed the most common computer security advice that experts offer to end-users in order to construct a set of Likert scale questions […]

Abstract We describe a web browser fingerprinting technique based on measuring the onscreen dimensions of font glyphs. Font rendering in web browsers is affected by many factors—browser version, what fonts are installed, and hinting and antialiasing settings, to name a few—that are sources of fingerprintable variation in end-user systems. We show that even the relatively crude tool of measuring […]

Abstract In response to the threat of phishing, web browsers display warnings when users arrive at suspected phishing websites. Previous research has offered guidance to improve these warnings. We performed a laboratory study to investigate how the choice of background color in the warning and the text describing the recommended course of action impact a […]

Abstract Password meters tell users whether their passwords are “weak” or “strong.” We performed a laboratory experiment to examine whether these meters influenced users’ password selections when they were forced to change their real passwords, and when they were not told that their passwords were the subject of a study. We observed that the presence […]

Abstract We performed a laboratory experiment to study the privacy tradeoff offered by Facebook Connect: disclosing Facebook profile data to third-party websites for the convenience of logging in without creating separate accounts. We controlled for trustworthiness and amount of information each website requested, as well as the consent dialog layout. We discovered that these factors […]

Abstract We measure users’ attitudes toward interpersonal privacy concerns on Facebook and measure users’ strategies for reconciling their concerns with their desire to share content online. To do this, we recruited 260 Facebook users to install a Facebook application that surveyed their privacy concerns, their friend network compositions, the sensitivity of posted content, and their […]
