Disclosed is a method for sharing Rights Object (RO) of a specific DRM content resident in a certain device with different devices (or terminals) in a Digital Rights Management (DRM) system, wherein a first device and a second device can share RO for DRM content by performing a mutual authentication between the first device and the second device to set a session therebetween; creating, by the first device, a second RO for the second device; and transferring the second RO from the first device to the second device through a particular interface. Thereby, while the first device consumes a specific DRM content with employing the first RO, the second device simultaneously consumes the specific DRM content with the second RO transferred from the first device.
