The team spoke to 26 Canadian adults who used shared smart speakers at home, including Amazon Echo, Google Home and Apple HomePod. They found that participants not only worried about keeping their data safe from the manufacturer or other entities; they also feared potential misuse of the device from people they actually live with and know.

"They worried that their housemates could order stuff online, overhear private conversations or access other people's reminders, calendars and phone contacts," explained senior author of the study Konstantin Beznosov, a professor of electrical and computer engineering who specializes in cybersecurity at UBC. "Of course, they were aware these actions could well be unintentional -- such as a child accidentally using the last-number-dialled feature to call up their parent's employer, for example."
