Client system and method of digital rights management and digital rights management system

Abstract

The invention provides a DRM client system, a method and a DRM system applying the DRM client system. The DRM client system comprises at least one application plug-in module used for generating a DRM client processing request according to a user request or an external application system request; and a DRM information processing module used for responding the DRM client processing request from the application plug-in module and receiving the digital data as well as performing decryption to the received digital data, wherein the DRM information processing module judges and selects the DRM strategy to be taken according to the DRM client processing request and the contents of the digital data and performs the corresponding decryption operation to the digital data according to the selected DRM strategy. According to the invention, the united processing platform can be provided for all the DRM systems, and the arbitrary application system has the DRM function by the DRM client system and the method.

Description

technical field [0001] The present invention relates to a system for digital rights management, in particular to a client system for digital rights management (DRM). Background technique [0002] DRM is the abbreviation of Digital Rights Management (Digital Rights Management), and its purpose is to protect digital products from illegal use. It provides a complete set of means for the commercial operation of digital media. The emergence of DRM technology makes copyright owners no longer need to spend a lot of time and energy negotiating with customers to ensure that digital media content can be used legally. DRM will enable content providers on various platforms, whether it is the Internet, streaming media or interactive digital TV, to provide more content, adopt more flexible program sales methods, and effectively protect intellectual property rights at the same time. [0003] DRM not only refers to rights protection, but also provides a complete set of solutions for the t...

AI Technical Summary

Problems solved by technology

[0008] However, existing DRM systems still have some disadvantages

First of all, because there is no unified standard for DRM, each company is developing its own DRM system, and each company will develop a corresponding DRM client for their DRM system, which greatly increases the difficulty and intensity of development, and different companies have The decryption algorithm is repeatedly developed in each DRM client, which wastes a lot of resources

In addition, the versatility of the existing DRM system is very poor, and each company has its own DRM system, which brings great inconvenience to users

At the same time, the promotion of products has also been greatly restricted.

In addition, the DRM client stores the digital license in the general storage unit of the local computer. This kind of storage has no security at all, and cannot prevent the local copy from being reused, and the decryption key is easily exposed during the decryption process. Exposed, DRM-protected files will have no security at all, and may be spread and used arbitrarily
