A bracelet to practice domestic counterintelligence

A bracelet to practice domestic counterintelligence

Large digital corporations have irretrievably entered our homes so that, through smart speakers and voice-controlled home assistants, the user plays at having a little digital slave at home. Although these little assistants are in charge for now of simple tasks such as turning the lights off and on, connecting the vacuum cleaner, looking for some information on the internet or playing music, they work 24 hours a day. Your price, our privacy

These domestic services pay the price of continuous surveillance by listening bots that, as in 'The lives of others', are permanently attentive to what is being said and said. Wife Ben Zhao had this feeling of suspicion when her husband brought home one of these assistants. Both are computer science professors at the University of Chicago.

With the help of another professor, Pedro Lopes, they have designed a wearable to precisely nullify the action of all these contemporary digital treats. Equipped with 24 speakers that emit ultrasonic signals imperceptible to humans, this bracelet generates enough noise to mislead the ears of Alexa and other assistants. A safe conduct for dystopia.
