    • A synchronizing method of delayed global data is provided to perform synchronization between a plurality of information devices, and information synchronization based on access authority for information between multi-users. A synchronizing method of delayed global data performs information synchronization between a server and at least one information device, and includes the steps of: forming a tree with the server(110) as a root, and the information device(120) as a leaf; generating packets periodically in the information device, and transmitting the packets to the server; and performing the information synchronization by the server receiving the packets from each information device. The step to form the tree includes the step of connecting the at least one information device with the server to form each middle node, and forming the leaf by connecting the information device with another information device.
