Demographics and sales data is a primary example of big data.
The tweeted advertisement system also looks like it's only recording demographics. Not individual personal IDs.
- logicallee 9y agoSorry, I wanted you to expand on this: "cashiers recorded buyer demographics by hand". Give me an example of what they used to record by hand. All I can think of is "male, adult". I am specifically interested in what else you say they used to record. I wasn't asking about the present status quo, only your historical statement about cashiers recording by hand.
- anabis 9y agoOh, OK. I edited in a link to the buttons the cashiers used, in the original post.
- logicallee 9y agoThank you! Obviously that is far less privacy violating than demographics could be. Today advertisers that phone home (spyware) often lie and claim only aggregate data is produced - but this manual example really is the kind of data that is okay. It's far less detailed than something like facial recognition. Thanks for adding the link!
