this 'parasite' protects your privacy by feeding smart speakers white noise

smart speakers aren’t always smart and sometimes they record things they shouldn’t. last may, a woman claimed that her amazon echo taped a private conversation and forwarded it to someone she didn’t know. then in december, a man asked for his data from amazon – and they sent him 1,700 recordings of someone else. fortunately though, designer bjørn karmann has taken it upon himself to come up with a hack, protecting users’ privacy. project alias is an open-source ‘parasite’ to train custom wake-up names for smart home devices while disturbing their built-in microphone.

project alias is designed to give users more control over their smart assistants, both when it comes to customisation and privacy. it’s composed of a 3D-printed top layer, a mic array, raspberry pi, and two speakers. it sits atop the a smart speaker like amazon alexa or google home, playfully made to look like a living organism that has taken over.

 

 

through an app users can train alias to react on a custom wake-word/sound, and once trained, alias can take control over your home assistant. equipped with speakers and a microphone, alias is able to communicate and manipulate the home assistant when placed on top of it. when not in use, alias makes sure the assistant is paralysed and unable to listen by feeding its’ microphones with white noise.

 

 

the wake word detection is made with a small neural network that runs locally on alias, which can be trained and modified through live examples. the app acts as a controller to reset, train and turn on/off alias. users can also create new custom functionalities and commands that the products were not originally intended for.

 

 

project alias is not available to buy as a retail product at the moment but karmann has made it possible for people to freely download the 3D printing building instructions and github code. that way, you can make sure your private information stays private.

 

 

‘we looked at how cordyceps fungus and viruses can appropriate and control insects to fulfill their own agendas and were inspired to create our own parasite for smart home systems‘, karmann explains.therefore we started project alias to demonstrate how maker-culture can be used to redefine our relationship with smart home technologies, by delegating more power from the designers to the end users of the products.
