Transfer passwords through the body? Today is reality

Nowadays sending personal information via connection wireless (WiFi and Bluetooth) is a method not sure. Any signal can in fact be intercepted and decoded. That is why researchers at the University of Washington have devised a way to convey the #password using only the #body human, using the sensors integrated in electronic devices. In this way, the transmission of passwords is even more secure.

The engineers of the Networks and Mobile Systems Lab, who have tested the sensors of smartphones and notebooks to look for those that transmit with a frequency below 30 MHz. The low frequency signals in fact pass through the human body, without propagating in the air. Fingerprint readers and touchpads were used to send passwords to an external device.

It works like this: the user could type the password on the smartphone or notebook and then touch the fingerprint reader or the touchpad. The low-frequency signal is then transmitted through the body and reaches, for example, the smart lock touched with the other hand. The system opens the door. “Let's say I want to open a door with a smart electronic lock,” he explained Mehrdad Hessar. "I can touch the doorknob and at the same time the fingerprint sensor on my phone and transmit the secret credentials to open the door through my body, without any personal information leaking into the ether."
