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 invention provides a method and a system for distribution of digital content in a peer-to-peer network. The method comprises the steps that: a content device receives a downloadrequest sent by a download client, wherein the download request comprises an uploading transaction identity and a license transaction identity of a content file required for downloading; the content device determines whether the download client has license information of downloading the content file or not according to the uploading transaction identity and the license transaction identity, and ifthe download client has the license information of downloading the content file, the content file is sent to the download server; when the content file is completely distributed, the content device sends a download transaction request to a content transaction processing device, wherein the download transaction request comprises download information; the content transaction processing device receives the download transaction request, the download information is determined to be valid, a download transaction is generated, and the download transaction is sent to a block chain processing device;and the block chain processing device receives the download transaction, and the download transaction is added into a block chain. The download server only has a download qualification, the content device can send the content file to the download server, so that the range of distribution of the content file is limited.

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. ...
