摘要： The present invention relates to a receiver information hiding method of hiding receiver information of a message in a system including a transmitting terminal broadcasting the message and a multitude of receiving terminals receiving the message, and the method includes selecting by the transmitting terminal at least one receiving terminal that has to process the message from the plurality of terminals, transforming by the transmitting terminal address information regarding the selected at least one receiving terminal, generating by the transmitting terminal the message using the transformed address information and broadcasting the generated message, and determining by each of the plurality of receiving terminals whether or not the corresponding receiving terminal is included in the selected at least one receiving terminal using specific address information corresponding to each of the plurality of receiving terminals and the transformed address information, in response to the reception of the message, and selectively processing or ignoring the message according to the determination result.
