Abstract
A method, a device, and a system for digital rights management (DRM), for measuring a usage amount of content used in a device. The DRM method of measuring a usage amount of content used in a device and reporting the measured usage amount to a server, includes: receiving policy information on the measuring or reporting including limitation information on the reporting from the server; and limiting usage of the content when the reporting is not performed according to the limitation information included in the received policy information. Accordingly, it is possible to prevent the content from being limitlessly used without allowing the user to report the usage amount of the content by limiting usage of the content, when the usage amount of the content is not reported based on the limitation information.
