Problems solved by technology
At the same time, the encryption and decryption of audio and video will consume a lot of time and server resources, and the efficiency is low
Finally, the particularity of the client also makes the user have to use a designated player to obtain the service, which brings a lot of inconvenience to the user

Embodiment
[0047] The streaming media DRM cloud service system of the B / S architecture of the present embodiment consists of four levels:
[0048] Client: The media resource requester is used to request media resources. It can be a simple player or a web page with a playback function, so that media resources can be accessed simply through the web page, forming a B / S architecture system.
[0049]Resource service interface: developed and implemented by cloud computing service providers. The resource service interface can be roughly classified into three parts: encryption module, decryption module, and application service module. The function of the encryption module is to encrypt media files according to relevant copyright information and a specific encryption algorithm; finally, generate a media file license certificate (such as figure 2 ). The application service module is used to store and manage the license; receive and process the application request sent by the client; process th...

The invention discloses a streaming media DRM (Digital Rights Management) cloud service system with browser / server architecture and an implementation method thereof. The system comprises a client side, a resource service interface, a virtual machine and a computer cluster, wherein the client side is a tool for a media resource requester to require resources; the resource service interface is arranged at a cloud service side, and is used for processing operation requests from a media provider, a media file requester or a backstage manager; and the cloud service side is provided with a service request, and a support for operation environment is provided for the resource service interface. According to the novel DRM system structure, not only is the client side simplified, so that a user can use conveniently without limitation of a certain player client side, but also the application of the DRM system with proprietary intellectual property rights is favored; the efficiency of encryption and decryption of media files is improved; and the service side is put on the cloud server, so that a system user has no need to repetitively set up an infrastructure, a computing platform and an operation environment, and the system is more stable and safer.
Description
technical field [0001] The invention relates to the technical field of streaming media DRM, in particular to a streaming media DRM cloud service system and an implementation method of a B / S architecture. Background technique [0002] At present, a general streaming media DRM (Digital Rights Management, content digital copyright encryption protection technology) system is composed of a streaming media resource management subsystem, an identity authentication subsystem and a client. The streaming media resource management subsystem is mainly used to manage streaming media resources and pack and encrypt streaming media data packets in real time. The encryption of the data packet is mainly by encoding the relevant watermark into the data part of the video data packet (video file, you can directly encode the fixed watermark into the video file in advance), and write the relevant copyright information into the data packet header at the same time. The streaming media resource mana...
