Characterizing ubiquitous systems privacy issues by gender and age was our goal. We selected two ubiquitous systems: a wearable system (Google Glass) and an embedded in context system (Smart Office). An online survey, with 400+ participants, which included questions about how people perceive privacy issues related to the use of these two different ubiquitous systems, was conducted. Results show that Google Glass generates a higher degree of concern than the Smart Office. Female participants tend to be more worried than male, independently of the ubiquitous system considered. Finally, the youngest participants (16 to 25 years old) are the most concerned about privacy threats, which was unexpected.
