Abstract: Biometric identification through intra-body communication is described. In one embodiment, a system for biometric identification includes a biometric transmitter device and a biometric receiver device. The biometric transmitter device includes at least one transmit electrode for contact with skin of an individual at a first location on the skin, and the biometric transmitter device is configured to transmit a signal through the transmit electrode and the skin. The biometric receiver device includes at least one receive electrode for contact with the skin of the individual at a second location on the skin, and the biometric receiver is configured to receive the signal through the receive electrode for biometric authentication of the individual.
