TED 2018: The smart home that spied on its owne

For two months in early 2018, technology journalist Kashmir Hill let innocent household items spy on her

She had turned her one-bedroom apartment into a "smart home" and was measuring how much data was being collected by the firms that made the devices.

Her smart toothbrush betrayed when she had not brushed her teeth, her television revealed when she had spent the day bingeing on programmes, and her smart speaker spoke to the world's largest online retailer every day.

It was like living in a "commercial, surveillance state" with "not a single hour of digital silence", she said.
