We collaborated with researchers from Strathmore University (Nairobi, Kenya), and I made the trip to evaluate the prototype and visit rural areas of Kenya in August-September 2016. Our paper summarising the results of a pilot study was accepted to the Symposium on Usable Privacy and Security (SOUPS), the leading security usability event, which I presented at SOUPS 2017 in Santa Clara, California in July 2017.
