Network environment-based universal digital copyright protection method

Abstract

The invention relates to the technical field of information security, in particular to a network environment-based universal digital copyright protection method. In the method, the use of multimedia files is monitored and managed through a network in real time without influencing the normal use by users, wherein the monitoring and management covers contents in monitoring and management: monitoring is to allow a server to acquire the state of the use of media by the users in real time, and management is to uniformly manage the authorities of the users for using various media by the server and allows the users to use the media after acquiring permission from the server. In the invention, the bandwidth requirements for use by the users are reduced, it is not required to acquire contents through the network in real time, the original using habits of the users are not changed, the centralized management of authority is implemented by the server, and the real-time authentication mode of theserver increases safety.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a general digital copyright protection method based on a network environment. Background technique [0002] Digital content itself is easy to copy, and the development of network technology has led to the proliferation of illegal transmission. On the one hand, the intellectual property protection of digital assets is passive and difficult to collect evidence afterwards. On the other hand, it dampens the enthusiasm of creators and merchants of media content, and affects the development of the media industry. In response to the demand, DRM technology has emerged. Using a general-purpose microcomputer as the client's content playback device, DRM actually prevents the machine's playback program from bypassing the control. [0003] When information content becomes electronic files, management is transferred from human beings to computer programs, and copyrights become ...

The poor network also prevents users from enjoying the viewing effect of local media

Fourth, this business model is acceptable for enjoying media (movies, music), but for document media, it is difficult to meet the needs of users for playback, page turning, jumping, and page-by-page printing, which will increase the cache on the server side pressure

In addition, this method still cannot absolutely protect the media content from being diffused. Now there are software tools that can buffer the streaming page in the client memory, and then save it as a plain text file and spread it.
