Comment on Sainsbury’s boss defends decision to sell customers’ Nectar card data
mannycalavera@feddit.uk 10 months agoThat’s no fun for the guardian. Gotta get those clicks with controversial misleading headlines. Totally not a tabloid, totally…
What this article fails to explain is what exactly they are selling and how that is matched up to groups of users. It also fails to explain how advertising is linked to anonymous users at the other end and how throughout all of this it’s just a random ID they are targeting rather than Mr Phillips from Doncaster. It doesn’t explain at all the mechanism to do this because it doesn’t match the narrative they want to push of outrage.
Never stop being the guardian, never stop. 😂🤣😂.

You absolutely can anonymise data.
However it’s also true that of you don’t do it correctly users can be identified. Sounds like Netflix didn’t do it properly. I don’t know, do you have a link I could look at?
anonymising data is a treadmill problem
what might work now won't hold up to the de-anonymising techniques of a few years from now
so no, you can't really
Create anonymous UUID, store interactions against this in a separate table, ensure PII is removed prior to storing. So instead of Max Reboo has purchased a subscription to jugs and hooters it’s user 12345678901234576 has purchased jugs and hooters. How can a future treadmill de-anonymise this? For sure if the storage is done badly then you can track back to a particular user.
Also, once again, can you link to the netflix issue you quoted above please. Thanks.

It looks like the Guardian is basing this off reports from Dispatches and The Times and iy seems that it's really mot quite clear how it works. Here's the de-paywalled Times report: https://archive.is/s5eDe
