A method of communicating information between an object and an information collection point via a short-range wireless network while protecting the privacy of a user of the object. Initially, a prompt is sent from the information collection point via the wireless network. The object detects the prompt and establishes a session by generating a random identifier for temporarily identifying the object, and sending the random identifier to the information collection point. The same random identifier is used throughout the session. No information permanently identifying the object is communicated to the information collection point until the information collection point is successfully authenticated to the object. Once this occurs, the object authenticates itself to the information collection point and communicates the information.
