alt Hacker News> We add noise to their data
It’s interesting that Apple is going down a similar path with hardware filtering location retrieval commands and neighborhood-level blurring on their C1 modems. Really awesome work from that team by making sure they’ve considered privacy as a first party feature for that chip.
How do you guys view the relative value of privacy/security at the network provider layer of the cell stack for the average user/citzen?
Even if Cape doesn’t retain metadata yourselves (eg LTE positioning info), is that data not still retained and repackaged by the tower owners themselves? Eg babel street, venntel, etc. A rotating IMEI every 24 hours might make it marginally more difficult for logical tracking, but there’s still only physically one location the phone can be in without fuzzing at the hardware level.
I should also say - I’ve been following y’all’s work for a while (and considered some of those early forward deployed engineer positions), but I’m struggling to see how this all works as a consumer product. Would be awesome to see an eventual partnership with Apple/Qualcomm to bring this to the hardware level since privacy is a tough nut to crack even at full MVNO.
Appreciate the shoutout. We love what Apple is doing in this area. There is a lot of room for them to help improve things at the modem/hardware/OS layer.
On the tower question, you’re right, we can’t control what data is collected by the tower owners. Like I said above our strategy is to add noise through a variety of methods that makes it harder (not impossible) for anyone collecting data to track you. We also give you multiple phone numbers. I think this stuff adds up and is a meaningful improvement over the status quo for most average user/citizens.
I like to use the organic food analogy. If given the choice, why not choose the carrier that is actually making an effort not to track you vs everyone else who clearly doesn’t care?
