Project Alias Preserves User Privacy

Last year, in May, a woman claimed that her Amazon Echo taped a private conversation and forwarded it to a person she didn’t know. And in December, a technical error resulted in Amazon sending an Alexa user 1,700 audio recordings of a stranger. Well, to guard your privacy a pair of developers have open-sourced a solution that prevents speakers like Google Home from listening in on people within earshot.

Project Alias And Privacy
