Congratulations to LERSSE alumni Azadeh Mokhberi whose Master Thesis research is presented on May 13th at ACM CHI, the premier HCI conference! Azadeh has interviewed 42 Facebook Marketplace (FM) users in the US and Canada, focusing on their experiences and the factors they consider during trading decisions on FM. Key findings from the study include:

Happy to help Privacy and Security subcommittee of ACM CHI ’24 technical program committee (PC). ACM CHI is the premier international conference of Human-Computer Interaction. Privacy and Security subcommittee is reviewing submissions reporting new techniques/systems/technologies, evaluations of existing/new systems, lessons learned from real-world deployments, foundational research identifying important theoretical and/or design insight for the community, etc.
Serving on USENIX Security ’24 PC
Happy to help USENIX Security ’24 by serving on its technical program committee (PC). As its call for papers describes “The USENIX Security Symposium brings together researchers, practitioners, system administrators, system programmers, and others interested in the latest advances in the security and privacy of computer systems and networks. … All researchers are encouraged to submit papers covering novel and scientifically significant practical works in computer security.”

I’m pleased to see that Netflix has implemented one of the design improvements that the study led by my former PhD student Dr. Borke Obada-Obieh recommended. Back in 2020, we have published study results at CHI ’20, the top HCI venue. Just before the conference (and weeks before the COVID-19 pandemic) Borke and I presented the study at Netflix headquarters. This is what we wrote in our paper:

Numerous information-tracking solutions have been implemented worldwide to fight the COVID-19 pandemic. While prior work has heavily explored the factors affecting people’s willingness to adopt contact tracing solutions, numerous countries have implemented other information tracking solutions that use more and more sensitive data.

With a remote workforce and everyone working digitally, the threat landscape increases. A team of my research group, led by PhD candidate Borke Obada-Obieh, performed the first qualitative study on employee security and privacy concerns when telecommuting.
Continue readingWhat Makes Security-Related Code Examples Different?
Reuse of code examples (CEs) in software engineering can impact code security. Azadeh Mokhberi, a PhD student in my research group, led an interview study to investigate developers’ habits, challenges, and strategies in the life cycle of using security-related code examples (SRCEs), with a focus on exploring the differences between security- and non-security-related CEs.

Over the last years, crypto-assets have gained significant interest from private investors, academia, and industry. While the user population and their motivations, perceptions, and behaviors have been studied, non-adopters and factors influencing their decision have been left unexplored.
Continue readingDiscovering Personas of Crypto-Asset Users
Crypto-assets are unique in tying financial wealth to the secrecy of private keys. Prior empirical work has attempted to study end-user security from both technical and organizational perspectives. However, the link between individual’s risk perceptions and security behavior was often obscured by the heterogeneity of the subjects in small samples. In a collaboration with the researchers from University of Innsbruck, Artemij Voskobojnikov, a PhD candidate in my research group, has conducted a survey of 395 crypto-asset users to discover three distinct types of such users.
Continue readingWhy Mobile Crypto-Wallets Are Hard to Use
Over the past years, the cryptocurrency domain has grown substantially. The corresponding user base has also changed significantly and is no longer only made up of cypherpunks and computer experts as was the case in the early days of Bitcoin. Managing these cryptocurrencies, however, has been found to be challenging for the users and it remains largely unknown what features of current wallets contribute to the poor UX, why, and to what extent. Artemij Voskobojnikov, PhD candidate in my research group, has led a collaboration with Freie Universität Berlin researchers that investigated this exact question.
