My grocery store wants to know my BMI
(lemmy.world)
If they were interested in my location they could request location data. What are the odds they are doing this to directly market products to people based on health data?
Inb4 “They already do that based on what you regularly purchase”
Of course, yes they do. This appears to be one more layer on top of it. And surely they wouldn’t share that information with the pharmacy, right?
Both wifi and Bluetooth has better anonymity options now via randomized client IDs, etc, but yeah I'd also like to see even better protocols.
Instead of just using antenna arrays for MIMO to maximize throughput you could instead use the arrays to reduce the signal strength for most traffic below the noise floor (like GPS) to make tracking much much harder. But it does add a lot of complexity too, and would probably be bad for batteries (the receiving end needs more power).
