Problems solved by technology

[0004] Although P2P content distribution technology speeds up the sharing of large-capacity files between networks and improves the utilization rate of network bandwidth, the control of the spread range of digital content files is not good enough, which may lead to unlimited spread of digital content files
Furthermore, it will lead to the inability to fully control the rights of digital content

Embodiment Construction

[0053] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0054] At present, P2P content distribution technology can accelerate the transmission efficiency of large-capacity files between networks and improve the utilization rate of network bandwidth. However, the transmission range of digital content under the P2P content distribution technology may not be limited, thus making it difficult to protect the copyright of digital content. For example: in the process of uploading or downloading mathematics content, it is not necessary to verify the consumer or the content device performing the upload or download. Consumers who do not own a license to the digital content can also download content from a content device. Alternativel...

Abstract

The embodiment of the present application provides a method and system for distributing digital content, including: the content device receives a download request sent by the download client, the download request includes the upload transaction identifier and the license transaction identifier of the content file requested to be downloaded; the content device receives the download request according to the upload transaction Identification and license transaction identification determine whether the download client has permission information for downloading the content file, and if so, send the content file to the download client; when the distribution of the content file is completed, the content device sends a download transaction request to the content transaction processing device, The download transaction request includes download information; the content transaction processing device receives the download transaction request, determines that the download information is valid, generates a download transaction, and sends the download transaction to the block chain processing device; the block chain processing device receives the download transaction and sends the download transaction added to the blockchain. Only with the download qualification, the content device will send the content file to the download client, limiting the distribution scope of the content file.

Description

technical field [0001] This application relates to the technical field of digital rights management, in particular to a method and system for distributing digital content in a peer-to-peer network. Background technique [0002] Digital Rights Management (DRM for short) is a technology developed with the widespread dissemination of electronic audio and video programs on the Internet. Its purpose is to protect the rights of digital content, technically prevent unauthorized (unauthorized) copying of digital content, or make copying difficult to a certain extent, and end users must be authorized to use digital content. DRM protects digital products such as software, music and movies, and can control and limit the use rights of these digital products. Thereby effectively protecting the copyright of digital content, protecting the legal benefits of digital content owners, increasing the enthusiasm of digital content creators and stimulating the development of digital content. ...
