A secure identification system is proposed in which a user gets access through an identification device or badge or tag (51) worn on his / her body, which applies the techniques of body coupled communication (BCC) to create a kind of aura around the user. An identification (ID) is communicated to a user interface of the secure identification system through BCC communication, and the user is authenticated by the system through an authentication procedure checking the identity of the user on the basis of an assumed secure BCC communication of the ID.

The present invention relates to coupler device, processing apparatus and method of processing a plurality of body-coupled communication signals which have been detected by using an electrode arrangement with a plurality of electrodes or electrode segments (40, 42; 40, 43). Respective transmission parameters of the body-coupled communication signals are estimated and at least one of a selecting and weighting processing is applied to the detected body-coupled communication signals based on the estimated transmission parameters. Then, the processed body-coupled communication signals are combined to generate a diversity output signal. Thereby, robustness against coupler misplacement and user convenience is increased in body-coupled or body-based communication systems.

A device for transmitting in multiple coupling modes has a transmission module (11), at least one periphery module (18), and an antenna (16, 17) for each of the multiple coupling modes. Further, in a method of switching between multiple coupling modes, switching is conducted between at least polling and listening phases of first and second coupling modes. The device and the method enable a seamless switching between e.g. a near field communication and a body coupled communication. Such a coupling or switching is particularly useful for performing secure transactions whereby through body coupled communication a body-worn tag is interrogated which provides a secure code for a transaction initiated through near field communication with a transaction terminal.

A device (100) which is placeable on or close to a human or animal body has at least a sensing unit (105) configured to capacitively sense a physiological signal from the human or animal body and capacitively communicate a body coupled communication signal.

In summary, the present invention relates to a device, a method, a system and a computer program enabling to ensure a reliable communication even under difficult radio frequency conditions. In case data cannot be successfully communicated by a radio frequency communication, the data may be transmitted to another device by a body-coupled communication via a human or animal body. The other device can act as a relay and forward the data to an intended destination. Thus, data may be successfully transmitted to the intended destination even under difficult radio frequency conditions due to body shadowing or other effects.
