Design And Application Of A Secure Sharing System For Observation Data Of Terrestrial Ecosystems Based On Blockchain

The scale of ecological data storage continues to expand with the expansion of research scales in the field of ecology,and the traditional centralized data storage method is increasingly unsustainable in the face of the growing amount of ecological data.Observation data is easy to repeat,tamper,share,and store in traditional databases and a few datum could be used effectively due to large amounts of data and high storage cost.Therefore,more and more ecologists hope to find more effective methods of data storage.At the same time,the blockchain technology derived from bitcoin transactions quickly gained popularity in the financial and insurance industries due to its advantages of low distributed data storage cost and a high degree of data security sharing.In this context,from the perspective of blockchain technology,this research has effectively implemented the combination of distributed storage and traditional databases,real-time monitoring of data released by the system,and real-time network users through the technical design of real-time data tag release and real-time data modification verification.The specific application of blockchain technology,such as data label query verification in the field of ecology,could promote efficient data sharing among ecologists.Additionally,this technology is less expensive than traditional data storage.Based on the understanding and mastering of information technology such as blockchain technology and underlying data storage technology,this research is based on the realities of ecological observation data such as its use and sharing.First,the functional and non-functional requirements are analyzed for ecological data storage.On this basis,this study examines the overall function of the blockchain-based terrestrial ecosystem observation data security system,including a detailed elaboration of the design ideas of each sub-module in the system.After that,the Python development language was used to complete the technical development work of the target system,and a variety of functions have been tested in this system.At last,we further improve and enhance the system function to ensure system effectiveness.Based on the classic C / S architecture and the executable script file framework design in the wx-python development mode,this research realizes the client-terminal of the ecological observation data security system that can quickly get started,and can effectively meet the common functions demanded by the field of ecology.Compared with the traditional centralized data storage method,this study adopted the blockchain technology,such as the Hash algorithm and timestamp technology,to ensure data security.We also try to apply the advantages of blockchain technology to ecological data management to solve the long-term difficulties in the safe storage and sharing of data in the field of ecology for providing a useful reference for subsequent related exploration.
