基于区块链技术的数字资产确权交易模型研究

A study of digital assets' copyright confirmation and transaction based on block chain technology

针对传统数字资产版权登记、签权、授权、交易等问题,提出基于区块链技术的数字资产确权交易模型;研究并设计该模型的逻辑结构及模型中数字签名、版权注册、区块链智能合约等模块的流程设计;在模型关键模块流程设计的基础上,重点结合数字签名技术、区块链智能合约、非对称数字加密等技术和相关的算法,实现了基于区块链技术的数字资产确权交易模型。最后,通过实验验证了模型中数字签名身份验证及数字内容解密算法的安全性和相关性能。

Aiming at the problems of copyright registration,signature,authorization and transaction of traditional digital assets,a model was put forward for the confirmation and transaction of the copyright of digital assets based on block chain technology.The logical structure of the model was studied as well as the process design of digital signature,copyright registration and smart contracts of the block chain in the model.On the basis of the process design of its key modules,the model for the confirmation and transaction of the right of digital assets based on block chain technology was realized by focusing on the combination of digital signature technology,block chain’s smart contracts,asymmetric digital encryption and related algorithms.Finally,the security and related performance of the digital signature authentication and digital content decryption algorithm in the model were verified by experiments.
