摘要:
A method for moving a rights object (RO) between devices, a method of using a content object based on the moving method, and devices using the methods are provided. The moving method includes performing authentication between two devices; securing a connection between the devices; and communicating the rights object between the two devices. The using method includes two devices communicating with each other, the first device having use permission of content objects and the second device including the content objects and corresponding rights objects; the first device searching for the content objects; and the first device using the content object that was found. The device includes an authentication module to authenticate another device; a security formation module to secure a connection for the other device; and a transceiving module which communicates a rights object for which the connection has been secured.

A method and apparatus for copying or moving a rights object having right information regarding digital contents between a device and a portable storage device to copy or move the digital contents there between are provided. According to the method and apparatus, the digital works can be prevented from being recklessly and randomly copied and moved, and therefore, copyright can be protected. In addition, data loss or unauthorized access can be prevented.
摘要:
An apparatus and method for managing a rights object by backing up and restoring the rights object between a host device and a multimedia card are provided. The apparatus includes an input unit that receives an order signal from a user, a rights-object-managing unit that determines whether the rights object can be backed up and restored based on rights object information when the order signal is input, and backs up and restores the rights object according to a result of the determination, and an information-managing unit that manages information related to movement and removal of the rights object and information on the backed up and restored rights object.
摘要:
An apparatus and method for operating many applications between a portable storage device and a digital device are provided. The method includes opening at least two logical channels from the digital device to the portable storage device through a physical channel, transmitting and receiving data between a plurality of applications of the digital device and a plurality of applications of the portable storage device through the opened logical channels, and closing the logical channels after finishing the transmitting and receiving of the data.
摘要:
There is provided a method and an apparatus for searching rights objects stored in a portable storage device by using an object location data. The method includes: accessing the portable storage device; transmitting an object identifier to the portable storage device; receiving a location data of a first object searched based on the object identifier from the portable storage device; storing the location data of the first object with the object identifier; and transmitting the location data of the first object and an operation data representing operations to be performed with the first object to the portable storage device by using the location data of the first object.
