Research On Key Technologies Of Enterprise Data Exchange Based On Blockchain

In the era of big data,enterprise data is generating faster and faster.In order to better release the value of data,enterprises must accelerate the process of data from static information carriers to dynamically transferred production materials through data exchange and sharing.At present,enterprises generally implement data exchange and sharing by establishing a data center.However,the data center sharing mode causes data to face different data security issues during the life cycle of exchange and processing.On the one hand,after the data belongs to the data center,the departmental data ownership boundaries are chaotic,which makes it difficult to guarantee the quality and authenticity of the data.It takes a lot of time and effort to verify the data,and it is not conducive to the correct matching of responsibilities.On the other hand,the data security problem inherent in the centralized structure,the single centralized decision structure has the problems of opaque data authorization and authentication process,and the unauthorized use of unauthorized data;and because the data has the characteristics of reproducibility and easy dissemination,it leads to The data is out of the control of the data center,and there is a problem that the unauthorized data cannot be controlled for secondary flow.In response to the above problems,this paper introduces blockchain technology in the traditional enterprise data exchange and sharing model,using the characteristics of blockchain decentralization,smart contracts,tamper resistance,traceability,etc.to build a transparent,efficient,and secure data exchange control frame.First,by carefully analyzing the key problems in the process of enterprise data sharing,the architecture and solutions of enterprise data exchange system based on blockchain are proposed,and a block-oriented data resource description model is defined to ensure that data resources are shared during the sharing process.Standardized description and clear confirmation of power,and use the anti-tampering characteristics of the blockchain to trace the data source to ensure data quality and authenticity.Secondly,combining the blockchain with the access control model,a blockchain-based access control mechanism is proposed,the access control strategy is stored in the blockchain,and smart contracts are used to implement strategic management and strategic decision-making functions.Effectively avoid the single point of failure and transparency of decision in the traditional centralized access control.Finally,using the method of computing migration,a data collaboration and sharing model based on blockchain smart contracts for on-chain recording and off-chain computing is proposed.By combiningcontainer technology to build an automatic,efficient and safe execution environment,the strategy of invisible data is realized to ensure that the data sharing process is safe,controllable,transparent and traceable.This article takes the blockchain as an entry point to enable enterprise data exchange and sharing,to study the application model of blockchain in enterprise data exchange and sharing.By using the blockchain to record data collection and exchange information,it solves the problems of data confusion and unclear flow direction,and uses the technical advantages of the blockchain to make up for the shortcomings of traditional enterprise access control models and data sharing models,and to address the problem of data being over-authorized.It not only reduces the frequency of data secondary flows but also reduces the risk of private data leakage and abuse.
