Ultrasound Could Protect Pacemakers From Hackers

You never want your wireless device open to attacks, but if that device is implanted inside your body, security becomes even more important. With pacemakers and other medical devices being controlled and monitored from afar, scientists say it's time to step up protection. Those concerns in mind, a group of researchers from the Swiss Federal Institute of Technology and the French National Institute for Research in Computer Science and Control have developed a new safety net.

According to Technology Review
, the system uses ultrasound waves to measure the distance between a medical device and the wireless reader trying to communicate with it. This could prevent potential hackers from wirelessly gaining access to private information stored on the device, draining its battery, or causing it to malfunction. With the ultrasound system, access to the device would be restricted to the physical proximity of the communicator. In the plan proposed by senior researcher Claude Castelluccia and his team, you'd need to go through a series of authentication steps and be within 10 meters of the device in order to gain access.

With technology's increasing presence in our anatomies, it's good to know that scientists are thinking about security. Knowing that the computer on our desk is susceptible to attacks is bad enough, but if a wireless device is keeping our heart beating, we want security to be tighter than Fort Knox.
