The U.S. Department of Homeland Security recently warned that various medical devices made by the company Medtronic, such as implanted cardiac defibrillators, are vulnerable to cyberattack. This is because a hacker could easily gain wireless access to the equipment’s settings and change them.
Purdue University researchers have built a prototype device that prevents medical device signals from radiating outwards. Instead, the signals are kept within the human body, effectively using a more secure “internet-of-body” to block remote hacks. This is made possible by facilitating medical device communication in the electro-quasistatic range, a much lower frequency than traditional Bluetooth communication.
