Abstract: Systems and methods for locally generating a license and activating a Digital Rights Management (DRM) agent are provided. The system includes a storage device and an electronic device. The storage device includes a DRM treated file, operation information, and a management application. The electronic device activates the management application from the storage device to retrieve information, such as a Unique Identification (UID) or a DRM machine certificate from the electronic device, and generate a license for the electronic device according to the operation information, and the retrieved information of the electronic device. The electronic device activates a DRM agent by providing the DRM treated file and the license to the DRM agent for playing back the DRM treated file based on the license. The management application may set the license expired after the DRM treated file is played back on the electronic device.
