摘要

A device authentication system and a method thereof are provided to enable a user to register his/her plural devices at once, thereby using provided contents in the plural devices. A plurality of devices(100) have device identifiers. A user client using the devices registers personal information and device identifiers. A management server(300) distributes the license provided from a contents server(400) and the license provided from a license server(500) to the devices to reproduce them. The contents server provides the management server with contents so that the contents can be reproduced in the devices. The license server gives the right for the use of the contents to the devices.
