Walmart, even when it's potential for misuse of customer data is taken to it's negative extreme, is just a vendor. Not a repository of your most private data. Walmart cannot deduce from your pictures printed at their photo kiosk if you are having an extra-marital affair. It doesn't have that kind of "putting together two and two" power. Plus it doesn't share that with your other family members or suggest to them that they get to know your extra-marital partner better.

Where am I going with this...scratch this reply.

If you can't see the potential for abuse at FB (or any other similarly massive soc-net) and somehow are trying to draw parallels to some big box vendor with no social tentacles, my explanation will not advance your understanding of it either.

No current corporation, conglomerate or organization - Disney, Visa, Experian, Equifax, Transunion, ExxonMobil, Monsanto - has that kind of established and potential scope for intrusion into your life.

Not even Acxiom has that kind of potential.

Sure they can. Let's suppose my purchasing history fits the profile of a married couple, maybe even with telltale signs like feminine hygiene products. The purchases are made on weekends, at whatever time married couples go shopping for groceries and other household essentials.

But suddenly there's a new pattern--at previously unexpected times, I buy incriminating products like condoms, cologne, unusual jewelry, stuff that doesn't fit the profile. I'm pretty sure Walmart can get a pretty decent probability that I'm having an extramarital affair. Why not? Target can already tell when you're pregnant, for instance.

I think that is a preposterous claim. Airlines know every vacation and business trip you've ever taken. Credit reporting agencies probably know more about your financial well-being than even you do. Heck, credit card companies know every financial transaction you perform.

I don't really buy the argument you started to form about how other companies can't "put two and two together." What makes you think that? Amazon certainly uses their data to make recommendations to me. Walmart can't personally target you in the store, but I'm sure they do with online purchases. There is nothing stopping Walmart from looking at your photos and deducing things, other than company policy and laws (so, the exact situation Facebook is in).

Yeah but airlines don't know if you are flying with your mistress or your sister.

And credit reporting agencies don't have your IMs, or know that you mailed hotchick2012 43 times this week, and started doing so 5 months before you changed your profile status from its complicated to single.

Walmart doesn't have facial recognition cameras up in every store tracking you. So you can just go to another store and make your purchase, keeping all your patterns intact.

The issue with putting 2 and 2 together is an issue which reared its head only post the camibrian era like IT explosion.

The old big box retailers do not have the same level of connection to your thoughts and personal information the same way online companies do.

They could do that, but only after they drastically upgraded themselves to specifically start profiling and tracking each individual - essentially by becoming more like facebook/social networks.

Your argument soars and falls depending on how connected to your personal information/social network a retailer is.

The only likely exception to that is your pharmacist - their domain of knowledge gave them pretty deep insights into your life even before the advent of the net.
