The CyLab Usable Privacy and Security Laboratory (CUPS) brings together researchers working on a diverse set of projects related to understanding and improving the usability of privacy and security software and systems. Our research employs a combination of three high-level strategies to make secure systems more usable: building systems that "just work" without involving humans in security-critical functions; making secure systems intuitive and easy to use; and teaching humans how to perform security-critical tasks.

CUPS is affiliated with Carnegie Mellon CyLab. CUPS students come from several CMU PhD programs including the programs in Societal Computing, Engineering and Public Policy, Human Computer Interaction, Computer Science, Electrical and Computer Engineering, and Public Policy and Management. We also work with masters students from several CMU programs including MSIT-Privacy Engineering. Prospective students should apply directly to these programs.

Privacy decision making

While most people claim to be very concerned about their privacy, they do not consistently take actions to protect it. Web retailers detail their information practices in their privacy policies, but most of the time this information remains invisible to consumers. Our research focuses on understanding how individuals make privacy-related decisions, finding ways to make privacy information more usable to consumers, and using soft-paternalism to provide privacy nudges. CUPS researchers developed a "nutrition label" for privacy and a search engine for bank privacy policies. We are also studying user attitudes about privacy on social networks, privacy for mobile apps, and as the usability and effectiveness of online tracking opt-out tools. Our Personalized Privacy Assistant Project aims to develop intelligent agents capable of learning the privacy preferences of their users over time, semi-automatically configuring many settings, and making many privacy decisions on their behalf. Our Usable Privacy Policy Project is developing approaches to extracting information from natural-language privacy policies and displaying that information in useful ways for users.

We have been working on several projects related to privacy choices and opt-outs, including a project related to the CCPA icon.

We have also developed an IoT Security and Privacy Label.

Passwords and authentication

To combat both the inherent and user-induced weaknesses of text-based passwords, administrators and organizations typically institute a series of rules – a password policy – to which users must adhere when choosing a password. There is consensus in the literature that a properly-written password policy can provide an organization with increased security. There is, however, less accord in describing just what such a well-written policy would be, or even how to determine whether a given policy is effective. Although it is easy to calculate the theoretical password space that corresponds to a particular password policy, it is difficult to determine the practical password space. Users may, for example, react to a policy rule requiring them to include numbers in passwords by overwhelmingly picking the same number, or by always using the number in the same location in their passwords. There is little published empirical research that studies the strategies used by actual users under various password policies. In addition, some password policies, while resulting in stronger passwords, may make those passwords difficult to remember or type. This may cause users to engage in a variety of behaviors that might compromise the security of passwords, such as writing them down, reusing passwords across different accounts, or sharing passwords with friends. Other undesirable side effects of particular password policies may include frequently forgotten passwords. In fact, the harm caused by users following an onerously restrictive password policy may be greater than the harm prevented by that policy. In this project, we seek to advance understanding of the factors that make creating and following appropriate password policies difficult, collect empirical data on password entropy and memorability under various password policies, and propose password policy guidelines to simultaneously maximize security and usability of passwords. We also explore the security and usability of some new types of passwords.

Security behavior

We aim to better understand the challenges that everyday people face when using their home computers over both the short- and long-term. Towards this goal, we are building and deploying data collection software that participants install on their computers, which provides metrics on a variety of computer and user behaviors.This data is then sent to our "Security Behavior Observatory." With this data, we hope to identify the causes and effects of usable privacy and security problems users encounter in daily everyday computing. This will provide insights to multiple research areas (e.g., behavioral economics, computer security, human-computer interaction, privacy, social sciences) on what areas most urgently need additional research as well as how we can better help users, developers, and organizations resolve these problems. (See our SBO website for information about participating in our studies.)

User controllable security and privacy

Managing security and privacy policies is known to be a difficult problem. It is important that new user interfaces be developed to effectively and efficiently support lay users in understanding and managing security and privacy policies - their own as well as those implemented by systems and individuals with whom they interact. Solutions in this area have traditionally taken a relatively narrow view of the problem by limiting the expressiveness of policy languages or the number of options available in templates, restricting some decisions to specific roles within the enterprise, etc. As systems grow more pervasive and more complex, and as demands for increasing flexibility and delegation continue to grow, it is imperative to take a more fundamental view that weaves together issues of security, privacy and usability to systematically evaluate key tradeoffs between expressiveness, tolerance for errors, burden on users and overall user acceptance; and develop novel mechanisms and technologies that help mitigate these tradeoffs, maximizing accuracy and trustworthiness while minimizing the time and effort required by end users. The objective of this project is to develop new interfaces that combine user-centered design principles with dialog, explanation and learning technologies to assist users in specifying and refining policies. One new policy authoring interface we have developed is a visualization technique for displaying policies in a two-dimensional "expandable grid". (See also the User controllable security and privacy project page, the Expandable grids project, Grey project, Usable security for digital home storage and Locaccino.)

Usable Cyber Trust Indicators

When systems rely on a "human in the loop" to carry out a security-critical function, cyber trust indicators are often employed to communicate when and how to perform that function. Cyber trust indicators typically serve as warnings or status indicators that communicate information, remind users of information previously communicated, and influence user behavior. They include a variety of security- and privacy-related symbols in the operating system status bar or browser chrome, pop-up alerts, security control panels, or symbols embedded in web content. However, a growing body of literature has found the effectiveness of many of these indicators to be rather disappointing. It is becoming increasingly apparent that humans are a major cause of computer security failures and that security warnings and other cyber trust indicators are doing little to prevent humans from making security errors. In some cases, it may be possible to redesign systems to minimize the need for humans to perform security-critical functions, thus reducing or eliminating the need for security warnings. However, in many cases it may be too expensive or difficult to automate security-critical tasks, and systems may need to rely on human judgment. In these cases, it is important to situate security indicators both spatially and temporally to maximize their effectiveness, and to design them to communicate clearly to users. The goal of this research is to systematically study the effectiveness of cyber trust indicators and develop approaches to making these indicators most effective and usable. We are currently focusing on security warning dialogs. See also our work on privacy indicators on our privacy decision making research page.

Earlier Projects

Looking for some of our work that you can't find under "current projects"? Check here for our past projects.

Supporting trust decisions

When Internet users are asked to make "trust" decisions they often make the wrong decision. Implicit trust decisions include decisions about whether or not to open an email attachment or provide information in response to an email that claims to have been sent by a trusted entity. Explicit trust decisions are decisions made in response to specific trust- or security-related prompts such as pop-up boxes that ask the user whether to trust an expired certificate, execute downloaded software, or allow macros to execute. Attackers are able to take advantage of most users' poor trust decision-making skills through a class of attacks known as "semantic attacks." It is not always possible for systems to make accurate trust decisions on a user's behalf, especially when those decisions require knowledge of contextual information. The goal of this research is not to make trust decisions for users, but rather to develop approaches to support users when they make trust decisions. Our research began with a mental models study aimed at understanding and modeling how people make trust decisions in the online context and ultimately resulted in the development of anti-phishing training tools and filtering software. The tools developed by this project our being commercialized by Wombat Security. For our publications, see the Supporting trust decisions project page.

Usable anonymity tools

A variety of tools have been developed to provide anonymity for various types of online interactions. Most of the work in this area has focused on improving the anonymity properties of these tools, and little has been done to improve their usability. We have been working on developing more usable interfaces for Tor.
