We already know how hackers can harm computers, smartphones and other technology. Few people is aware that under the threat of hacking and there are other devices that are directly connected to health and even life of people. These include electrical pacemakers, which in theory can be hacked and bring a man to death. Such cases in the history as yet, but researchers are already looking for a way to protect people from terrifying danger.
Typically, implantable medical devices communicate with each other through Bluetoothconnection. The range of the network reaches 10 meters, and in theory sent between the two signals can catch any person in the vicinity. For example, an attacker is able to enhance the function of your pacemaker and kill someone.
We connect more and more devices to the network of the human body, from smart watches and fitness trackers to virtual reality helmets on the head. The challenge is not only to preserve the security of this communication, but also in ensuring higher throughput and lower energy consumption.
Shreya sen, Professor of electrical engineering
Engineers from Purdue University have created a device that narrows the Bluetooth range is up to 0.5 inches. It uses the conductive properties of the human body to create a closed network to which you cannot join, no third-party device. The device not only provides protection against burglary, but also consumes 100 times less energy than an “open” network.
At the moment, the prototype resembles a very thick watch, but in the future the developers intend to reduce it to the size of the chip mounted on any medical device. In addition, he will ensure the safety of people, the device can be useful for doctors — they will be able to configure implantirovannogo electronics without surgical intervention, through the control panel.
