Abstract

The invention discloses a digital rights management evaluation device for an intelligent terminal, and the device comprises a simulation module which is used for responding to a first instruction, and running a second operation system of the intelligent terminal to be evaluated in a first operation system of the evaluation device; the simulation module is also used for responding to a second instruction input by the user through the system interface of the second operating system and running a media content playing program in the second operating system; the monitoring module is used for acquiring monitoring data of the second operating system in the process of running the media content playing program; the data sending module is used for sending the monitoring data to the safety evaluation module; and the security evaluation module is used for receiving the monitoring data and evaluating whether the to-be-evaluated intelligent terminal has a digital copyright management security risk or not according to the monitoring data so as to obtain an analysis result.

Description

technical field [0001] The present invention relates to the technical field of digital rights management (DRM), and more specifically, to a digital rights management evaluation device for smart terminals. Background technique [0002] With the continuous advancement of media convergence and broadcasting broadband, smart terminals begin to support the operation of 4K / HDR (High-Dynamic Range) content. On the one hand, the rapid update and iteration of smart terminals has brought more threats and challenges to content protection. On the other hand, 4K ultra-high-definition content has higher and higher requirements for content protection due to its high production cost. Moreover, with the development and operation of content providers' 4K ultra-high-definition content and services, content providers, especially large film companies, have put forward higher requirements for copyright protection, especially copyright protection on smart terminals. [0003] The existing digital ...
