Much of human communication is now mediated by online social networks. Twitter, Facebook, and Youtube now compete for our collective attention in much the same way as television, radio, and newspapers did for previous generations. But contemporary online social media are qualitatively different from media of the past. Online communication leaves a record of who said what to whom, when, and on what topic.

Household Internet-of-Things (IoT) devices are intended to collect information in the home and to communicate with each other, to create powerful new applications that support our day-to-day activities. Existing research suggests that users have a difficult time selecting their privacy settings on such devices. The goal of this project is to investigate how, why and when privacy decisions of household IoT users are suboptimal, and to use the insights from this research to create and test a simple single user interface that integrates privacy settings across all devices within a household.

Numerous surveys find that Internet users want to limit the personal data that is being collected about them, as well as control the usage of their data. Existing and proposed regulation in the U.S. accords users such rights, in the form of a "transparency and control" obligation on personal data collectors: users should be informed about the rationale of requests for personal data so that they can make an informed decision on whether or not to disclose their data.

Human beings have evolved to detect and react to threats in their physical environment, and have developed perceptual systems selected to assess these physical stimuli for current, material risks. In cyberspace, the same stimuli are often absent, subdued, or deliberately manipulated by malicious third parties. Hence, security and privacy concerns that would normally be activated in the offline world may remain muted, and defense behaviors may be hampered.

Large-scale Internet censorship prevents citizens of many parts of the world from accessing vast amounts of otherwise publicly available information. The recognition and publication of these censorship events have aided in motivating the development of new privacy-enhancing technologies to circumvent the censor. We argue that as circumvention technologies improve and the cost of detecting their use increases, adversaries that are intent on restricting access to information will seek out alternative techniques for disruption.

The more people use the Internet, the more they risk sharing information they don't want other people to know. Tor is a technology that every day helps millions of people protect their privacy online. Tor users -- ranging from ordinary citizens to companies with valuable intellectual property -- gain protection for the content of their online messages and activities, as well as whom they interact with and when. For the most part, Tor is very secure. However, it has a known vulnerability to an attack called website fingerprinting.

This project aims to assess how online data impacts the hiring process. In an ideal situation, one might imagine that employers hire the most skilled applicant, but sociological research indicates that this may not be the case. A job applicant's similarity to the interviewer in class background and class-based leisure activities often matters as much or more to employers than a job applicant's skills or work experience.

Over the past decade, people have realized that failure to account for human factors has resulted in many software security problems. Yet, when software does feature user-centric design, it takes into account average user behavior rather than catering to the individual. Thus, systems designers have gone from designing for security experts to now appealing to the least common denominator.

Designing secure systems and validating security of existing systems are hard challenges facing our society. For implementing secure applications, a serious stumbling block lies in the generation of a correct system specification for a security policy. It is non-trivial for both system designers and end users to express their intent in terms of formal logic. Similar challenges plague users' trying to validate security properties of existing applications, such as web or cloud based services, which often have no formal specifications.

Social media systems have transformed our societal communications, including news discovery, recommendations, societal interactions, E-commerce, as well as political and governance activities. However, the rising popularity of social media systems has brought concerns about security and privacy to the forefront. This project aims to design trustworthy social systems by building on the discipline of network science.
