摘　　要：基因数据作为极具私密性的个人数据资产,其隐私保护和价值化已成为当前的研究热门。但目前基因检测行业采取的仍是传统的基因数据共享模式,存在着个人基因数据所有权丢失、基因数据隐私性弱、共享多方协作性差等问题。鉴于此,设计基于区块链的基因数据共享模型,利用区块链技术的去信任化、可追踪溯源等特性,明确个人基因数据的所有权的归属;利用密码学技术和可信硬件,保证基因数据的隐私性;利用智能合约处理共享方间共享流程,建立安全可行的基因数据共享模型,作为基因数据价值流转的技术支撑。最后,简单实现基因数据安全共享操作平台,比较模型的优势并作出安全性分析。Genetic data is a very private personal data asset,and its privacy protection and value has become the current research hot.However,the genetic sequencing industry is still adopting the traditional gene data transaction mode,which has some problems such as the loss of personal gene data ownership and weak privacy of gene data and poor cooperation between sharing parties.In view of this,this paper proposes a genetic data sharing model based on blockchain.It made use of the trust-removing and traceability characteristics of blockchain technology to clarify the ownership of individual genetic data.The privacy of genetic data was guaranteed by using cryptography technology and reliable hardware.The smart contract was used to deal with the sharing process among sharing parties,and a safe and feasible gene data sharing model was established,which served as the technical support of gene data value transfer.The secure sharing platform of gene data was simply implemented,the advantages of the model were compared,and the security analysis was made.
