We just returned from the ISSNet Annual Workshop, held in Victoria BC this year. Several students from the lab presented their work:
Gerardo Reynaga gave a research talk about his work on the usability of captchas for mobile devices.
Leah Zhang gave a research talk on her interactive comic for teaching about password guessing attacks.
Vanessa Boothroyd presented a poster on her user study comparing older and younger adult’s online behaviour and perception of online risk.
Sana Maqsood presented a poster on her design, prototype, and user study of a password system for flexible displays.


Leah Zhang and Sana Maqsood were selected to attend the CRA-W Graduate Cohort worshop in Boston earlier this month. Both presented posters of their research. Leah presented her work on interactive visualizations to teach about password guessing attacks and Sana presented work on a gesture-based password system for flexible mobile displays.



Leah Zhang’s short paper on security education visualizations has been accepted as a Research Note at the GRAND Annual Conference.
