A set of smart vending machines at the University of Waterloo is expected to be removed from campus after students raised privacy concerns about their software.
The machines have M&M artwork on them and sell chocolate and other candy. They are located throughout campus, including in the Modern Languages building and Hagey Hall.
Earlier this month, a student noticed an error message on one of the machines in the Modern Languages building. It appeared to indicate there was a problem with a facial recognition application.
“We wouldn’t have known if it weren’t for the application error. There’s no warning here,” said River Stanley, a fourth-year student, who investigated the machines for an article in the university publication, mathNEWS.
Also this is data that any reasonable company could get in like half an hour of searching and asking.
There is data on how many meals are sold a day at the mensa, how many students are enrolled, how many students live on campus…
Unless the vending machine is in the last corner of the third floor of an half empty building, all this information can be puzzled together to get a good estimate of how many people are passing the machine on a day to day basis.
