区块链技术在数字媒体资产版权保护中的应用

Application of Blockchain Technology in Copyright Protection of Digital Media Assets

摘要: 随着“互联网+”时代的到来，以自媒体为代表的大众创新蓬勃发展，知识产权保护作为创新活动的推进剂和保护伞，在创新过程中起着重要作用。由视频、音频、图片、文字转化而来的数字化内容依托互联网平台得以迅猛发展，网络版权产业为整个经济的增长做出了巨大贡献。然而由于缺乏有效的信息技术支持，数字媒体资产版权保护还存在版权容易受到侵犯、中心化版权登记方式效率低下等问题，这些问题在传统的版权保护体系下较难解决。区块链具有去中心、去信任、可追溯以及防篡改等特性，将区块链技术与数字媒体资产版权保护相结合能有效地解决这些问题。本文将介绍区块链的特点和关键技术，分析将区块链技术应用在数字媒体资产版权保护的可行性，并在此基础上构建基于区块链技术的数字媒体资产版权交易系统的初步技术方案。

Abstract: With the arrival of the “Internet+” era, mass innovation represented by “we media” has been developing vigorously. And intellectual property protection, as the driving force and umbrella for innovation activities, plays an important role in the innovation process. Digital content transformed from video, audio, picture and text has been rapidly developed relying on the Internet platform. And the Internet copyright industry has made great contributions to the growth of the entire economy. However, due to the lack of effective information technology support, there are many problems in copyright protection of digital media assets such as easy infringement of copyright and low efficiency of centralized copyright registration, which are difficult to be solved under the traditional copyright protection system. Blockchain has the features of decentralization, trustless, traceability and tamper-proof. Above problems could be solved effectively by combining blockchain technology with the copyright protection of digital media assets. This paper will introduce the features and key technologies of blockchain, analyze the feasibility of applying blockchain technology to the copyright protection of digital media assets, and build a preliminary technical scheme of the copyright transaction system of digital media assets based on blockchain technology.
