    摘要： A method and apparatus for acquiring and removing information regarding a digital rights object are provided. The method for acquiring removing information regarding a digital rights object includes receiving a request for data on a rights object from a device, processing the data on the rights object in response to the request, and providing the processed data to the device. The method of removing a digital rights object includes selecting information regarding a rights object to be removed, encrypting the selected information regarding the rights object using a common encryption key, embedding the encrypted information regarding the rights object into a signal to be transmitted to a portable storage device, and transmitting the signal to the portable storage device. A device requests information regarding a rights object from a portable storage device, receives the information regarding the rights object from the portable storage device, and removes an unnecessary rights object.
