Application Research On User Identity Confirmation And Data Paid Sharing Based On Domestic Cipher Algorithm And Blockchain

With the continuous development of information technology such as the Internet and cloud computing,information application has penetrated into all aspects of our daily lives.The "Tenth Five-Year Plan" is pointed out that strengthening personal information protection and expanding data open shareholdings are significant of accelerating information construction.However,in current informatization applications,the security problems of users' personal information leakage often occur.Mainly because the user's personal information is re-collected by different services and applications when realizing identity confirmation,and the user uses a single account and password to simplify complicated account management issues,which increase the risk of user personal information and account leakage.In terms of data sharing,there is a problem that users' legitimate data rights and interests cannot be protected,mainly due to the current lack of user-specific data sharing platforms and services,and users' lack of initiative and right to benefit from data sharing.In addition,issues such as privacy leakage and difficulty in ensuring the authenticity and integrity of data involved in data sharing also restrict the circulation of user data.In response to the above two problems,this paper respectively proposes a secure user identity confirmation scheme and a data paid sharing scheme based on the domestic cipher algorithm and blockchain.Among them,the secure user identity confirmation scheme completes the verification of the legality of the service and application through the blockchain,and uses the public key cryptographic algorithm in the domestic cipher algorithm to realize the identity confirmation of the user securely when using the service and application.We also designed a client application for account security management.The data paid sharing scheme is based on the first scheme.By designing a unified data sharing platform and service,users can realize the free combination and sharing of data in different services and applications under the premise of ensuring privacy and security,and obtain corresponding benefits.Cryptographic algorithms and blockchain also ensure the authenticity and integrity of shared data and the security of data circulation.In order to verify the feasibility of the schemes proposed in this article,this article built a blockchain network,designed and implemented the user account security management client prototype and the unified data sharing platform prototype.All three are implemented in the form of web applications,and the database uses domestic Dameng Database,interactive communication uses HTTP protocol.Theoretical analysis and experimental test results show that the schemes proposed in this article have high security and feasibility,and can solve the problems of identity conformation and data sharing in the current information application,and realize the protection of user's personal information and data rights and interests.
