Thanks for the detailed answer. That’s fascinating.
To be clear , you’re suggesting that there’s a map of labels (diapers, cereal etc) to marketing ids so apple can still say they anonymize your data even though for all intent and purposes, they don’t?
- davismwfl 6y agoCorrect, this is how some data aggregators sell your purchase data without actually selling your receipts. You will have a number of marketing id's from different aggregators, but people like Amazon, eBay etc will aggregate from multiple sources and can track you across aggregators. And there are re-targeting and re-marketing companies that do this as a service. It lets them say they never sell your data, but they do sell meta-data about you. Probably a little over simplified but you get the idea.
- mrsmee89 6y agoWow! If you tell someone that you purchased #123 and they know that #123 is shampoo, how is that not the same exact thing as telling them that you bought shampoo? I’m shocked at the sliminess of this.
- eb0la 6y agoYou can guess this product affinity with a list of previous purchases. Just take a look at the 'arules' R package (https://github.com/mhahsler/arules https://github.com/mhahsler/arules). You don't need to identify the customer. I did some work with an online supermarket some time ago and I found some interesting associations worth trying like Sliced Brioche Bread + Nutella :-) Sadly I didn't find any association like 'beer and diapers' ;-)
