Abstract: A management server comprises a memory section including at least two memory areas, a message reception section which receives a message, a message conversion section which converts the message and generates a transmission message and a message transmission section which transmits the transmission message to a specified destination, wherein the memory section stores in the memory areas a temporary Identification (ID) link in which a real ID of a user and a temporary ID of the user are associated, and wherein the message conversion section converts, in a case where the message includes a first temporary ID which corresponds to a real ID and is stored in a first memory area, the first temporary ID to a second temporary ID which corresponds to the real ID, on a basis of the temporary ID link stored in a second memory area, and generates the transmission message.

Abstract: A system, which is connectable to a first apparatus capable of data communication using a data communication protocol via a network where each session is managed by a session management protocol, includes: a connecting section which, if ID about the first apparatus exists in a storing section when a start instruction is received from the first apparatus, registers ID about a session corresponding to the start instruction in association with the ID about the first apparatus, and establishes a path enabling data communication for the first apparatus in the network using the session management protocol; and a providing section which, upon receiving the ID about the session from a second apparatus, transmits confirmation information according to the result of confirmation about whether the ID about the first apparatus is in association with the ID about the session.
