But the data, if sold, could also be a windfall for marketers, and the implications are easy to imagine. No armchair in your living room? You might see ads for armchairs next time you open Facebook. Did your Roomba detect signs of a baby? Advertisers might target you accordingly.
Jamie Lee Williams, a staff lawyer at the Electronic Frontier Foundation, a digital rights group, said information about the size of a home and the amount of furniture in it could allow advertisers to deduce the owner’s income level. Eventually, it might even be possible to identify the brands the owner uses.
“Especially combined with other data, this is going to be able to reveal a ton of information about what people’s lifestyles are like, what people’s daily patterns are like,” Ms. Williams said.
…What happens if a Roomba user consents to the data collection and later sells his or her home — especially furnished — and now the buyers of the data have a map of a home that belongs to someone who didn’t consent, Mr. Gidari asked. How long is the data kept? If the house burns down, can the insurance company obtain the data and use it to identify possible causes? Can the police use it after a robbery?
…“Your friendly little Roomba could soon become a creepy little spy that sells maps of your house to advertisers,” tweeted OpenMedia, a Canadian nonprofit.
