Abstract
A beacon device transmits a challenge message to each of one or more responder devices over a respective direct communication link, inviting each responder device to prove the existence of its respective direct communication link by transmitting to a respective recipient device, distinct from the beacon device, a respective response message indicating knowledge of contents of the challenge message. A predetermined time period after its transmission of the challenge message, the beacon device transmits a confirmation message indicating knowledge of the contents of the challenge message to a message store. A validation device then compares contents of each response message which preceded the confirmation message in time, if any, to contents of the confirmation message and infers therefrom which of the respective responder devices, if any, received the challenge message over the respective direct communication link.
