Preventing a brave new world11/11/2022 ![]() ![]() "That is, without any other action on the part of the users, the devices discover each other's presence, recognize that they are on the same body (and transitively learn from the wrist device whose body), develop shared secrets from which to derive encryption keys, and establish reliable and secure communications." It could automatically and securely connect to peripheral devices that are placed in a pocket, ingested, or implanted. They proposed a device that's worn on the wrist like a watch or piece of jewelry. "Techniques exist for collecting some of this information, but today's body-worn sensors lack the ability to reliably determine who is wearing the device." "Reliably interpreting data from a body-worn sensor often requires information about who is wearing the sensor as well as the current person's environment, location, current activity, and social context," the authors of the Usenix paper wrote. In the case of wearable devices, it's crucial that they also authenticate the identity of the person who's using it. ![]() But it also comes with a catch: researchers have devised proof-of-concept hacks that can disable or sabotage electronic pacemakers or deliver fatal insulin dosages over the air. ![]() Allowing the devices to connect wirelessly to computers or other devices saves money and can eliminate the number of invasive surgeries needed to keep them in working order. Over the past decade, there's been an explosion of tiny networked devices that manage a variety of health maladies, from regulating the beating of the human heart to controlling serious diabetic conditions. #Preventing a brave new world skinA separate paper recently penned by many of the same scientists envisions a similar device that uses heart rates, galvanic skin response, or other physiological data as a shared secret that can be used to securely share encryption keys among sensor nodes attached to the same body. Computer scientists have proposed a wearable healthcare device that uses unique physiological signatures in a patient's heart rate or other physiological response to prevent tampering by malicious hackers.Ī research paper presented on Monday at the 3rd Usenix Workshop of Health Security and Privacy describes a health sensor that measures the unique electrical properties of a patient's body to recognize their identity. ![]()
