"The AI tool can’t make it any worse." Investigating Developers’ Security Behavior with AI Assistants in a Password Storage Study

Past research showed that software developers often require explicit instructions to implement security measures. With the rapid rise of AI assistant tools such as ChatGPT, it remains unclear whether AI assistance supports or undermines secure practices, whether explicit security instructions are still essential, and…

Sensing Your Vocals: Exploring the Activity of Vocal Cord Muscles for Pitch Assessment Using Electromyography and Ultrasonography

Vocal training is difficult because the muscles that control pitch, resonance, and phonation are internal and invisible to learners. This paper investigates how Electromyography (EMG) and ultrasonic imaging (UI) can make these muscles observable for training purposes. We report three studies. First, we analyze the E…

It Shouldn't Be This Difficult: Researcher Perspectives on Diversity and Inclusion in Usable Privacy and Security Research

While recent usable privacy and security (UPS) research has made progress in moving beyond “the average user,” a systematic account of how UPS researchers navigate diversity and inclusion in their work remains lacking. Through 20 in-depth semi-structured interviews with experienced researchers, we examine how and why…

Robust Methods for Developer Screening in Rapidly Evolving AI Contexts

The rise of AI-powered tools like ChatGPT enables non-programmers to bypass programming screening questions, undermining internal validity in usable security and privacy, and software engineering studies. Past ChatGPT-resistant tasks proposed static visual questions, which ChatGPT can now circumvent. Therefore, we tes…

Certified AI System = Trustworthy? Exploring Expert and Lay User Perceptions and Needs Regarding AI Certification

AI certification has emerged as a promising mechanism to enhance transparency, accountability, and public trust. However, end-user perspectives remain largely unexplored. This study investigates two groups with differing AI expertise. Through qualitative interviews with 30 participants (15 experts, 15 lay users), we e…

"That's another doom I haven't thought about": A User Study on AI Labels as a Safeguard Against Image-Based Misinformation

As generative AI is increasingly contributing to the spread of deceptively realistic misinformation, lawmakers have introduced regulations requiring the disclosure of AI-generated content. However, it is unclear if labels reduce the risk of users falling for AI-generated misinformation. To address this research gap, w…

Campus AI vs. Commercial AI: Comparing How Students and Employees Perceive their University’s LLM Chatbot vs. ChatGPT

As the use of LLM chatbots by students and researchers becomes more prevalent, universities are pressed to develop AI strategies. One strategy that many universities pursue is to customize pre-trained LLM-as-a-service (LLMaaS) chatbots. While most studies on LLMaaS chatbots prioritize technical adaptations, these s…

Women Security Experts Are Not The Enemy: A Qualitative Study on Gender-Related Communication Challenges

Effective communication is crucial for meeting security needs, yet gender-related communication challenges faced by women security experts within software development remain underexplored. In an interview study with 25 women security experts, we investigated gender-related communication challenges hindering the adopti…

The TaPSI Research Framework - A Systematization of Knowledge on Tangible Privacy and Security Interfaces

This paper presents a comprehensive Systematization of Knowledge on tangible privacy and security interfaces (TaPSI). Tangible interfaces provide physical forms for digital interactions. They can offer significant benefits for privacy and security applications by making complex and abstract security concepts more intu…

Bridging the Gap Between Usable Security Research and Open-Source Practice — Lessons From a Long-Term Engagement With VeraCrypt

VeraCrypt is a freely available open-source encryption tool popular with tech-savvy users. In a 4-year effort to improve VeraCrypt’s usability to reach less tech-savvy users, we conducted 3 user studies (N=77) and found that participants struggled to successfully encrypt their devices with VeraCrypt. We iteratively re…
