Ordinary WiFi can now identify you with near-perfect accuracy
- Shadowmist 2mo agoHow do I wire this to Home Assistant?
- forsalebypwner 2mo agoUsing this: https://github.com/francescopace/espectre https://github.com/francescopace/espectre
- Shadowmist 2mo agoThat is really cool, thank you for sharing. Now all I need is alerts when my two cats who don't get along are close to each other.
- mike2872 1mo agoYou can also try out tommysense
- toomuchtodo 2mo agoAre there any projects or products today available for monitoring heart rate and respiration without needing a smart watch using this technology?
- dotancohen 2mo agoNo
- forsalebypwner 2mo agoYes actually, but I don't think it's technically allowed/legal in the US in the eyes of the FCC, not sure about other countries. It utilizes 77GHz FMCW, I got one for free but they retail for about $100. The part number is R77ABH1 Edit: sorry, you said "using this technology" and I missed that - this doesn't uses the same tech
- toomuchtodo 2mo agoNo worries, I presume it’s only a matter of time with consumer grade wifi and machine learning.
- khriss 2mo agoHeart rate, no, but monitoring breathing is possible using mmWave radar(eg 60 GHz Doppler radar nowadays, or the 5.8 GHz band earlier). Resmed S+ was probably the most well known, but it's been discontinued for a while now. If you search around, you can still find such devices.
- upboundspiral 2mo agoUnless we get legislation passed that bans this use in public and private spaces prepare for this to be combined with Flock et al to track your movements inside your house (already is being tested by some internet providers), track the moment you exit your house, track you along your route, track you inside all the business you visit. Unless we do something, this will be used to covertly break the fourth amendment.
- montroser 2mo agoThis would be extremely difficult to detect and enforce.
- iamnothere 2mo agoIt’s invasive enough that we will need to do something about it, even if perfect enforcement is not possible. 6G wireless already plans to include these features as well. The business model needs to be made unviable or illegal somehow, perhaps under anti-stalking grounds. Individuals may use this tech themselves, and businesses may use it on their own premises, which seems fine—the problem is with large scale deployments.
- upboundspiral 2mo agoThe Supreme court recently already ruled against warrantless mass surveillance along the lines you describe: https://www.aclu.org/press-releases/aclu-applauds-important-supreme-court-decision-making-clear-location-data-is-protected-by-fourth-amendment https://www.aclu.org/press-releases/aclu-applauds-important-... What we need now is laws that turn this ruling into action and policy.
- iamnothere 2mo agoThat’s for the government, on fourth amendment grounds. But I also don’t want private companies doing this on a wide scale even for non-governmental use.
- close04 2mo ago> These signals, known as beamforming feedback information (BFI), are transmitted without encryption, meaning that anyone within range can potentially read them. > By analyzing that information, the system can generate images of people from multiple viewpoints. Those images can then be used to determine a person's identity. This is the extent of the description of the magic sauce. Why are those images so unique that you can’t trick the algorithm? I can’t think of any EM based identification that can’t be tricked by adding layers of reflectors or absorbers in various points - a mask, special paint, etc.
- mmooss 2mo ago> "By observing the propagation of radio waves, we can create an image of the surroundings and of persons who are present," Notice that it doesn't matter if you are using Wifi. If you're in a city, I doubt there are many places that lack Wifi radio waves. Thank you to the researchers (seriously) for revealing this to the public rather than selling it to the highest bidder. Though I suspect that, given how obvious it is once you think about it - all these radio waves solve many problems of passive imaging - it's already known to some people.
- im3w1l 2mo agoWifi imaging has been a publicly known technique for years. I think the news is more how good it's gotten.

- im3w1l 2mo agoI'm personally bearish on privacy. As the cost of surveillance comes down we will see more and more actors able to conduct surveillance until even bored kids with pocket money and an afternoon can do it. Denying the """good""" guys the capabilities that all the bad guys have will be an absurdity. We will simply have to adapt to it.
- goda90 2mo agoHow do we adapt?
- iamnothere 2mo agoNever do anything that any group of people (or disturbed individual) might take issue with. Never accidentally date or marry an abuser. Never contest the absolute authority of whoever is in power. Simple enough, right?
- reorder9695 2mo ago"Oceania had always been at war with Eastasia."
- RamRodification 2mo agoReminds me of that Michael Scott quote: Don't ever, for any reason, do anything, to anyone, for any reason, ever, no matter what, no matter where, or who, or who you are with, or where you are going, or where you've been, ever, for any reason whatsoever.
- im3w1l 2mo agoBy creating a culture of live and let live. Maybe giving some activities legal protections that didn't use to need them in the past. Non-discrimination rules related to them. And being more careful than ever to not let a government be elected that would abuse all the information it now has on its citizenry. More democratic safeguards.

- hollow-moe 2mo agoWhat a time, conspiracy theorists being accidentally correct and their tools become somewhat useful. Does this count as a Torment Nexus story ???
- thataccount 2mo agoI came from the era before WiFi. One doesn't HAVE to have WiFi. Everybody keeps thinking they do. Same thing with cell phones. The world existed before all that, and it can exist just fine again without it.
- bcraven 2mo ago"Exist" is a low benchmark to hit. Very few people would be willing to trade in the opulence of today.
- thataccount 2mo agoIt wasn't that before was "less opulent". In many ways, it was "more opulent".
- kemotep 2mo agoWell if every business and home and public place has WiFi or Cellular technology with these capabilities it doesn’t really matter if you don’t they will still be able to use it to track you. This is why something has to be done to stop it. Radio transmission of data is over 100 years old we aren’t turning the dial back on that, but this one specific application of it to track people is and that’s the problem.
- thataccount 2mo agoEMF can turn it back in about 20 seconds.
- ButlerianJihad 2mo ago"EMF" is electromagnetic frequency, which is the general topic under discussion. Perhaps in context, you are referring to "EMP" instead?
- thataccount 2mo agoA pulse is a specific frequency of EMF.
- iamnothere 2mo agoGood time to invest in companies that make (extremely expensive) RF shielding paint and fine wire mesh.

- OrderlyTiamat 2mo ago> almost 100% accuracy I think it's annoying that this gets repeated without revealing the actual stats: this is for the BFI test, it's 99.5% ± 0.38, where 40 samples per person were split 80-20 in training and testset. paper: https://dl.acm.org/doi/abs/10.1145/3719027.3765062 https://dl.acm.org/doi/abs/10.1145/3719027.3765062
- ranger_danger 2mo agoNo it can't. I'm sorry but this article is quite sensationalist and is twisting their words around. What we can do is identify that a person-like object exists in a room, not necessarily Sally Jones from 123 Main St, as they try to imply by saying they are "able to infer people's identities with almost 100% accuracy." What they're claiming is science fiction.
