Authentication based on through-body signals detected in body area networks

A method performed by at least one processor, the method comprising:

• receiving, by the at least one processor of a receiving device, a signal that is transmitted through at least a portion of a body of an individual, wherein the signal is transmitted from a sending device to the receiving device while the sending device and the receiving device are both in physical contact with the individual, wherein the sending device is communicatively coupled to a door controller mechanism that controls a door;
• determining, by the at least one processor, a body signature for the individual based at least partly on an alteration of the signal that is caused by propagation of the signal through at least the portion of the body of the individual;
• and
• communicating, by the at least one processor, the body signature to a computing device, wherein the computing device is configured to:
• authenticate the individual based on the body signature;
• and
• send an access signal to the sending device in response to authenticating the individual, wherein the access signal is configured to instruct the door control mechanism to open the door to provide access to the individual.

One or more non-transitory computer-readable media storing instructions which, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• receiving a signal at a receiving device, wherein the signal is transmitted from a sending device and through at least a portion of a body of an individual to the receiving device while the sending device and the receiving device are both in physical contact with the individual;
• determining a body signature for the individual based at least partly on an alteration of the signal that is caused by propagation of the signal through at least the portion of the body of the individual;
• and
• providing the body signature to a computing device configured to authenticate the individual based on the body signature, wherein the computing device is configured to send an access signal to the sending device or the receiving device in response to the authenticating the individual, wherein the access signal is configured to enable the individual to access at least a portion of a client application executing on the sending device or the receiving device.
