Privacy policies are often too long and difficult to understand, and are therefore ignored by users. Shorter privacy notices with clearer wording may increase users’ privacy awareness, particularly for emerging mobile and wearable devices with small screens. In this paper, we examine the potential of (1) shortening privacy notices, by removing privacy(More)
People share personal content online with varied audiences, as part of tasks ranging from conversational-style content sharing to collaborative activities. We use an interview- and diary-based study to explore: 1) what factors impact channel choice for sharing with particular audiences; and 2) what behavioral patterns emerge from the ability to combine or(More)
Despite their ubiquity, many password meters provide inaccurate strength estimates. Furthermore, they do not explain to users what is wrong with their password or how to improve it. We describe the development and evaluation of a data-driven password meter that provides accurate strength measurement and actionable, detailed feedback to users. This meter(More)
With the rapid deployment of Internet of Things (IoT) technologies and the variety of ways in which IoT-connected sensors collect and use personal data, there is a need for transparency, control, and new tools to ensure that individual privacy requirements are met. To develop these tools, it is important to better understand how people feel about the(More)
FULL REGRESSION RESULTS In this section, we present additional explanations of how we fit our password-guessability regression models, in addition to providing the full results of these models. We first ran a Cox Proportional-Hazards Regression with all three design dimensions (composition policy, feedback, and stringency), as well as interaction terms for(More)
Text passwords—a frequent vector for account compromise, yet still ubiquitous—have been studied for decades by researchers attempting to determine how to coerce users to create passwords that are hard for a‹ackers to guess but still easy for users to type and memorize. Most studies examine one password or a small number of passwords per user, and studies(More)
