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.
On May 11, 2018, with my UBC colleagues and PhD students, we have organized first full day event, where over 20 projects from UBC related to cybersecurity have been showcased. Over 170 attendees had come to UBC Cybersecurity Summit to see the projects. The summit also featured a keynote by CMU’s Professor Dr. Prof. Lujo Bauer and Gary Perkins, CISO for the Province of British Columbia. See more details on the summit web site. Stay tuned for Cybersecurity Summit 2020.
Modern mobile operating systems implement an ask-on-first-use policy to regulate applications’ access to private user data: the user is prompted to allow or deny access to a sensitive resource the first time an app attempts to use it. Prior research shows that this model may not adequately capture user privacy preferences because subsequent requests may occur under varying contexts. To address this shortcoming, LERSSE’s PhD student Primal Wijesekera led a collaboration project with Dr. Egelman‘s Berkeley Laboratory for Usable and Experimental Security (BLUES) to implement a novel privacy management system in Android, in which contextual signals are used to build a classifier that predicts user privacy preferences under various scenarios.

In my undergraduate course on security, we are holding a mini-conference on December 4, where each team of 3-4 students will present their term project. Project topics are diverse and practical. The mini-conference is open to public. See its schedule for location information and presentation times. The projects will be evaluated by the representatives of the high-tech industry.
