Hi, what’s the best privacy friendly protocol for outside in public, if one can’t use wired connection, for e.g : earbuds, keyboard ?
- I remember reading that, at malls for instance, there are bluetooth beacons (same as wifi hotspots https://youtube.com/watch?v=79InT9cVtMM ), which are able to, somehow, provide an ID of yours (e.g android/google ID) to advertisers, saying “this guy was hanging 10 meters around this brand shop for an extended period of time, would you like to send them ads of your brand?”
- This summer I tried a pair of bluetooth earbuds, and despite scanning and the buds being ON, my host device couldn’t see them, as long as I didn’t hold on a pairing button procedure.
- So it’s nice to see that not any device 10 meters around the buds could see that they are nearby. However it’s very uncommon, in my experience 99% of the time, BT buds just automatically go in pairing/broadcasting mode upon power ON… So everyone around can see their presence…
- I don’t know, maybe there’s a version of bluetooth implementation to target, you guys tell me…
- wireless 2.4 / the USB dongle way, seems better at first, as nobody around could see my devices listed, but anything involving a dongle isn’t secure against one-time physical access = tampering ( https://www.syss.de/fileadmin/dokumente/Publikationen/2017/2017_06_01_of-mice-and-keyboards_paper.pdf )
- Also I’ve read in the past that it’s fairly easy with few tools to listen on local police/company/event radio channels (talkie walkies). I believe they use 2.4 GHz but don’t know anything about radio stuff. So are these proprietary dongles privacy-safe or not?
Out of subject : why I can’t post anything on reddit subs r/Privacy, r//Privacytools io, r//PrivacyGuides ? It would be better for us that our ISP / DNS provider knows that we browse reddit instead of privacyguides dot net I think Bluetooth vs. wireless 2.4GHz outside?
