Nudging Security Behaviors: Exploring Notifications in Antivirus Software
-
The motivation for this user study was to explore the effectiveness of using a notification in laptop antivirus software to encourage users to use a mobile version of the software on their smartphone.
04
Predicting User Behavior: The Factors and Perceptions Which Influence Device Specific Behavior
-
The motivation for this survey study was to explore how factors that influence behavior and users' mental models of security work together to influence the security behaviors and mechanisms users use on their devices and how these mental models, factors, and security behaviors might differ based on the device platform being used. The platforms compared in this study were traditional computing devices (laptops and desktops), smartphones, and tablets.
03
Device Specific Mental Models of Security
-
The motivation of this project was to explore the similarities and differences in mental models of security across traditional computing devices (laptops and desktops), smartphones, and tablets and their effect on users' security behavior on each platform. This interview study sought to identify users' perceptions of risk on each device platform and the actual security behaviors and mechanisms they utilized on each device.

UISA- User Interface Security Assessment
-
UISA is a method for assessing the security risk of user interface design.
-
Current contribution: Conducting user studies to evaluate the UISA process and improve the associated handbook and instructions.

Privacy Preferences vs. Settings: A Case Study of Android Permissions
-
The motivation of this project was to understand the difference between user's stated privacy preferences and their actual behavior regarding privacy and security decisions. This case study compares users' expressed comfort, their desired permission settings, and their actual permission settings for 9 specific Android permissions.
