Abstract: Methods, systems and devices enable synchronizing obscured identification information between a wireless identity transmitter and a central server to support one-way communication of the obscured identification information to the central server. The wireless identity transmitter may be a compact device configured to broadcast messages, such as through Bluetooth® advertisements, including an obscured identifier for receipt and relay to the central server by proximate proximity broadcast receivers via sighting messages that may also include location information. The central server may decode received identification codes to identify the wireless identity transmitter. The wireless identity transmitter may create message data by concatenating identifying information with an incrementing nonce, encrypting the concatenated information, and truncating the encrypted information. Alternatively, concatenated identification information may be encrypted with a pseudo-random function and a secret key known by the central server. The central server that may compare received data to pre-calculated encrypted data.
