I am planning to get my first implants, currently considering xMagic, NeXT, and FlexSecure.
As a privacy conscious person I would like to learn more about what if any persistent identifiers exist that could potentially be used against me by an adversary in scan range (which I realize is quite small).
I find the ability to rewrite sector 0 of the magic chip to be reassuring, but I am cognisant my current level of understanding of these technologies is low. I wanted to inquire here about this potential risk and see how reality lines up with my perceptions.
I would appreciate any facts or opinions on this topic, pertaining specifically to the xMagic, NExT, and FlexSecure.
Can you elaborate a little bit on the scenario you’re envisioning?
Are you concerned about someone being able to fingerprint and then track your chips, type thing?
If so, the read range of even the best implants maxes out at only a few inches, you can effectively follow someone with no tools at that range
Plus, they’d have to know you have them to begin with…
If someone could theoretically read your chips from further away, they could fingerprint you based on the data on the chip, on the xMagic all of the unique info that I can think of can be controlled by you, but until you manually overwrite them you’d be finger-printable
The NExT is a different story since the UID can’t be overwritten, if someone could read it, it could be used to identify you reliably
Some chips do have the ability to randomize their UID, if that’s a serious concern for you, although since those are a little less common just having one could sometimes be considered a stand-out characteristic…
Yes, I mean someone could read the ID when my identity is known, then read it again in the future when perhaps I don’t want my identity to be known (deanonymization)
I recognize this is a bit far fetched but it is a serious concern for me. Not because I am involved in sensitive or illegal activities, but simply because I highly value my privacy.
I don’t think it would be any worse than any other distinguishing marks you may have in practice
No one is likely going to be able to read it without actively looking for an implant, and if they know you have an implant to begin with then finding one is probably identifying regardless of the data on it, if that makes sense?
But I am certainly interested to see what everyone else has to say about it too, it’s a good question
You have an HF implant without a changable UID (NExT, xNT, FlexSecure, flexDF2, etc) and a kbr1 for your laptop.
You find yourself traveling non-permissive country, and [insert law enforcement here] finds this laptop near a crime scene, and separately you, a non-citizen.
They figure out what the KBR1 is, do some research on DT, rub up on your hands, and locate the implant. They slap your hand on the KBR1 and the laptop unlocks.
They are rightfully or wrongfully confident that the laptop contains undesirable data. You are now linked to this laptop. You are now in an uncomfortable situation.
This is kind of what I envision, though its poorly thought out, some variation of this is plausible.
