MANAGEMENT PROGRAM, MANAGEMENT DEVICE AND MANAGEMENT METHOD

PROBLEM TO BE SOLVED: To associate contents between multiple management devices while keeping an ID used in own device confidential.SOLUTION: When a management device 100 sends contents 110, it sends the contents after converting an in-device ID given to the contents 110 to a temporary ID. The management device 100 which has received the contents 110 having the temporary ID converts the temporary ID given to the received contents 110 to an in-device ID of own device and identifies the contents 110 using the converted in-device ID. By this way, each management device 100 can keep the in-device ID credential as long as it keeps information about the association of the temporary ID and the in-device ID credential, because the in-device ID can not be recognized from the outside. Between management devices 100, the contents 110 can be associated through the temporary ID.
