Abstract? ? This paper mainly introduced a collaborative sharing scheme of meteorological data that integrated user system,data interface service system and block chain network service system by using block chain technology,combining big data privacy protection and extensibility scheme and relying on data sharing. Through the platform,data exchange could be recorded to ensure data traceability and prevent data tampering and forgery.Meanwhile,contribution incentive mechanism was established to increase the enthusiasm of meteorological data sharing,which could provide accurate meteorological data and scientific basis for meteorological decision service,meteorological disaster prevention and mitigation,and scientific research and learning.
Key words? ? meteorological data;block chain;sharing scheme
我國是一個(gè)自然災(zāi)害多發(fā)的國家,其中氣象災(zāi)害約占70%,各種氣象災(zāi)害每年都給社會經(jīng)濟(jì)帶來巨大損失。隨著氣象信息化建設(shè)和服務(wù)水平日益提高,氣象信息已經(jīng)成為國民生產(chǎn)生活中不可或缺的一部分,公眾對氣象數(shù)據(jù)的需求也逐漸增加,但是目前氣象數(shù)據(jù)一直面臨協(xié)作共享難、數(shù)據(jù)安全與隱私保護(hù)難、數(shù)據(jù)確權(quán)難以及數(shù)據(jù)收益分權(quán)難等問題,數(shù)據(jù)壟斷、數(shù)據(jù)孤島等現(xiàn)象非常突出。隨著區(qū)塊鏈技術(shù)的發(fā)展,目前已進(jìn)入到可編程社會的階段,并且區(qū)塊鏈具有數(shù)據(jù)透明、真實(shí)的特點(diǎn),可以解決信任問題,從而有效促進(jìn)數(shù)據(jù)協(xié)作共享[1-2]。鑒于氣象部門自身及相關(guān)行業(yè)對氣象數(shù)據(jù)的使用需求,本文利用區(qū)塊鏈與大數(shù)據(jù)結(jié)合,提出氣象數(shù)據(jù)共享方案,研究解決氣象數(shù)據(jù)的保護(hù)問題和可拓展性問題,以期為相關(guān)工作的開展提供準(zhǔn)確的氣象數(shù)據(jù)。……
