PURPOSE: A distributed object system based on duplication and a providing method thereof are provided to perform communication and access between objects by a call or a function call in a client system without a network, thereby reducing a communication delay. CONSTITUTION: An interest module(120) determines admission or withdrawal for an interest group of a predetermined entity or a client system. A duplication module(130) reduplicates a real entity which exists in a server and joins in the interest group, as a shadow entity in the client system or deletes the shadow entity based on a determination result. A control module(110) synchronizes the shadow entity which exists in the client system and the real entity corresponding to the shadow entity.
