Secure Passwords Able To Be Sent Through The Body, University of Washington Study

The team discovered that by using benign, low-frequency transmissions generated by devices such as fingerprint sensors and touchpads, they were able to transmit data using both the sensors and the human body.

Usually sensors use signals to receive data about the user’s finger. The team created a way to output these signals to correspond to data contained in a password or access code. The data, when entered on a smartphone can travel through a user’s body to a receiver in a device, which can then confirm the person’s identity.
