Benefits of technology
The present invention is a method and system for a mobile terminal that improves the management of protected content by acquiring multiple rovers in a batch processing manner. This helps to increase the efficiency of rover acquisition.
Problems solved by technology
However, without copyright protection policy, the advanced network environment and technologies are likely to be used for illegal distributions of the contents.
DRM technologies attempt to protect the digital contents through all the phases of creation, distribution, use, and abrogation; and restricts access and usage rights of the user on the digital contents.
However, the conventional DRM system has a drawback in that the RO acquisition or update process is performed item by item such that it is time consuming and cumbersome to acquire or update multiple ROs.
That is, since the ROs required for consuming DRM content objects are purchased one by one, the user should perform the purchasing process repeatedly as many as the number of the DRM content objects, resulting in user inconvenience.
These repeated RO purchase transactions are time-consuming and cumbersome, resulting in contents management inefficiency and user inconvenience.
