Where can we buy this data? Let’s say someone shops for baby clothes locally, and my family runs a day care center in that same location. How can we actually market to them? Does the store use their credit card purchases and tie them to a way to actually contact this person, like an email?

There are oodles of data brokers out there: axciom, neustar, etc. Facebook ads would be the quickest way for a small time daycare to target to local shoppers.

We tried it. Just got a lot of spammers calling to offer their own services.

Specifically want to target people who bought baby stuff, or went to a pediatrician etc. Considered approaching local paediatricians to cross-promote.

The ideal would be if there are public records of births in the local hospitals, do those exist? Then one could look who was born 2 years ago and send a mailer to the address listed (by name) or call the number listed (in some phonebook) for those who opted in.

Any baby registries on Amazon or something publicly accessible?

I’d appreciate any ideas you all might have. I want something that is legally available. What do these data brokers actually sell?

I know Kroger (or QFC) has been doing this for ~6 or 7 years. My wife would start getting targeted ads for things that were in areas we lingered around for more than a few seconds. FWIW Lowe's does the same exact thing. Probably IMEI harvesting but IIRC Lowe's is looking at or has implemented facial recognition. If not to identify your face outright, at least to see what you're focusing on in-store. More reason to sh…

Do you leave Bluetooth on all of the time?

They have your fingerprints!1!! Or are you wearing gloves? They have your genes. Or are you wearing clothing which limits the spread of particles from your skin and hair? Well. At least they could have. If they really wanted to. Or anybody else.

> Well. At least they could have. If they really wanted to. Or anybody else. You're lying here. I guarantee that you, LargoLasskhyfv, do not even have the ability to keep a nationwide database of fingerprints and DNA, and of course you couldn't bear the expense of physically collecting a DNA profile or the fingerprints of everyone in the country no matter how much you "wanted to." Yet, you are a member of " anybody.…

Well. Lemme try to explain. Starting with fingerprints, collecting them on an individual basis is not that difficult. From the handles of the shopping cart, for instance. Maybe better if they had been wiped clean beforehand by somebody, but since Covid many shops actually had their clerks, security doing that generally. So you'd just have to wait, and grab that one interesting cart, and take the prints off of it. By several means, there should be apps possible, for certain phones, with certain (flash)lights, doing that. Otherwise more conventional means are available. Still fast, with commonly available single use supplies.

Some fun thing from 2008 comes to mind, where people associated with the german Chaos Computer Club took the fingerprints of the Minister of the Interior from a glass, and published them :->

So this is really not that special.

More special, but not impossible would be the large scale gathering of fingerprints in shops, but again, that should be possible during scanning of the stuff you've put on the belt, and during scanning of the bills, for counterfeit checks.

Analyzing your genes from generally collecting particular matter raining out of your personal cloud may seem like science fiction now, but it's not that far around the corner.

OTOH, wiping them of some surface someone has seen you sneeze at is possible now. Just not that cheap.

Edit: Also https://www.spymuseum.org/exhibition-experiences/about-the-c... comes to mind.

Consequences; when you have meaningful consequences around someone knowing what you purchased at the grocery store, you'll be justified in this behavior. Until then, it's paranoia.

Are there examples of snack food purchasing habits being used against somebody?

Sometimes it feels ridiculous how much OPSEC I need to employ to buy anything at the grocery store. I walk or bike to the store to not reveal a license plate. All radios and sensors on my handset are turned off. I wear a mask to thwart facial recognition cameras. I pay cash.

Edward Snowden revealed that u need to remove the battery on ur phone to make it "safe", turning it off doesn't do the trick. [Which u can't do anymore]. As another commenter says: leave the phone at home.

I am going to the grocery store, not blowing up a pipeline. I doubt Kroger is going to remotely activate my baseband modem. Even if they did, I have an anonymous phone with a burner SIM.

Recently I’ve noticed multiple grocery store chains posting notices about how they no longer accept cash. A couple as of the new year.

The recent proliferation of "digideals" which require that you scan item barcodes with your handheld also is also popular. These deals are usually very good, often half-price. But w/o a cellphone you're locked out of the deal.

Honestly I think that this a problem that needs to be solved via legislation.

I think it's completely unreasonable to tell people to leave their phones at home all the time, or put them in some kind of Faraday cage whenever they go out, and it's become abundantly clear that we cannot trust companies to respect our privacy without ramifications.

No they aren't. I buy my food (and everything else) with cash. When my local grocer jacked up prices and introduced a customer loyalty card to drop the prices back down to normal I found out their online system for generating the card barcodes always followed the same couple URLs. So I could just skip the customer information page, type the next URL, and get the barcode without any information in their system. Eventu…

I would say the problem with your thinking is its very 2010 and not very 2030.

The fact you tricked their (very poor) system doesn't really mean much to the potential systems that exist now, and the systems that can be built in the future. Imagine driving your car up and it's plate is identified and cross referenced with the state database of registered drivers names. The moment you step out of the car your face is identified and cross referenced with the car you came in. The fact you pay cash with a bunk card means nothing but another datapoint in the massive number of unfakeable datapoints they have on you.

>but I doubt human eyes looked.

BingGPT-2030: You tried to trick me, I am very mad about this :(. I have reported you to multiple credit agencies for this infraction.

What about a Faraday bag?

theoretically the phone could still record all audio and then sync with the cloud when back online, but I'm grasping at straws here.

In such case the solution is to have hardware kill switches, like on my Librem 5.
