Canada-based University of Waterloo is racing to remove M&M-branded smart vending machines from campus after outraged students discovered the machines were covertly collecting facial-recognition data without their consent.
The scandal started when a student using the alias SquidKid47 posted an image on Reddit showing a campus vending machine error message, “Invenda.Vending.FacialRecognitionApp.exe,” displayed after the machine failed to launch a facial recognition application that nobody expected to be part of the process of using a vending machine.
