Description

technical field [0001] The present invention relates to a rental component, a program, and a method for renting a component. Background technique [0002] Unlike analog content, digital content, such as music content, can be copied multiple times without loss of quality. Therefore, the recent rapid increase in the processing speed and storage capacity of the Internet and PCs (Personal Computers) has also increased the illegal distribution and exchange of content without the permission of the copyright owner of the content. [0003] In an attempt to prevent these illegal activities, a copyright management system based on DRM (Digital Rights Management) technology intended to limit the distribution and use of content has gained popularity.

Problems solved by technology

[0005] However, the copyright management system described above has a problem in that the copyright management block of the system for managing the use of content according to its license is individually designed and installed according to the usage restriction capability of the system and, for example, the type of user device, so that almost Lack of versatility and scalability

That is, prior art related copyright management blocks are not based on module configurations suitable for different content use cases, such as reproduction, copying, moving, renting (or payment), return (or check-in), and storage, thereby Full use of content cannot be performed across multiple user devices

In addition, as mentioned above, prior art-related licenses are written using different usage conditions, and at the same time, they are not written in a limited class for the above-mentioned usage cases, so there is a problem of poor portability

Therefore, it is difficult for a copyright management block with a specific installation to properly determine the usage condition for evaluating each usage situation from the license corresponding to another installation.
