Securing the Body Internet

As the body internet continues to expand,   hacking of devices and cnnections is possible, , but has never been done.   The system of devices and connections can be hacked.     Now work at Purdue shows how the signals involved can be restricted.

Your body has internet—and now it can't be hacked

The human body carries electrical signals well. Now these signals can be contained within close proximity of the body, thanks to new technology developed by Purdue University engineers.... :  

Someone could hack into your pacemaker or insulin pump and potentially kill you, just by intercepting and analyzing wireless signals. This hasn't happened in real life yet, but researchers have been demonstrating for at least a decade that it's possible.

Before the first crime happens, Purdue University engineers have tightened security on the "internet of body." Now, the network you didn't know you had is only accessible by you and your devices, thanks to technology that keeps communication signals within the body itself.

The work appears in the journal Scientific Reports. Study authors include Shreyas Sen, an assistant professor of electrical and computer engineering at Purdue, and his students, Debayan Das, Shovan Maity and Baibhab Chatterjee.

"We're connecting more and more devices to the human body network, from smart watches and fitness trackers to head-mounted virtual reality displays," said Sen, who specializes in sensing and communication systems.

"The challenge has not only been keeping this communication within the body so that no one can intercept it, but also getting higher bandwidth and less battery consumption," he said.

Body fluids carry electrical signals very well. So far, so-called "body area networks" have used Bluetooth technology to send signals on and around the body. These electromagnetic waves can be picked up within at least a 10-meter radius of a person.  ... "  ...
