Some pacemakers are accessible wirelessly for reprogramming, but the trouble is that this easy access could be abused maliciously. Sure, passwords would keep the devices safer from such intrusions, but the patient could forget or lose those. Solution? Password tattoos.
By tattooing passwords onto patients with ink that can only be seen under a UV light, doctors would have an easily accessible password in case of an emergency and patients would have an additional layer of security protecting their medical gadgets.
The idea certainly isn’t perfect nor is it being put into use yet—after all, the whole issue of how to handle password changes still hasn’t been resolved—but it’s good to see that research is being done for the sake of protecting medically necessary technology. [Microsoft Research via ]
