Storing Cryptographic Keys with Invisible Tattoos
This idea, by Stuart Schechter at Microsoft Research, is—I think—clever:
Abstract: Implantable medical devices, such as implantable cardiac defibrillators and pacemakers, now use wireless communication protocols vulnerable to attacks that can physically harm patients. Security measures that impede emergency access by physicians could be equally devastating. We propose that access keys be written into patients’ skin using ultraviolet-ink micropigmentation (invisible tattoos).
It certainly is a new way to look at the security threat model.

Hmm,
“Security measures that impede emergency access by physicians could be equally devastating. We propose that access keys be written into patients’ skin…”
Now let me think, the skin is the outer “wrapping” of the meat bag, and is perhaps the place most likely to be “not available” due to minor or major injury (think grazes through to full on burns and even grimed in dirt oil etc from an accident)…
Plus do you actually want to have a mark on you that will light up in a night life entertainment place when the MC/DJ turns on the UV light…
