摘" 要: 針對當前數據審計系統在實際應用中存在的數據泄露、數據損壞以及第三方審計人員身份泄露等隱私保護問題,設計一種基于區塊鏈的老年數據審計系統,并基于此提出一個可監管的匿名身份認證方案。系統采用非對稱加密算法和群簽名算法確保數據通信和存儲的安全性,且能夠實現身份證書的匿名性,具有一定的隱私保護能力。此外,如果第三方審計人員出現非法行為,可以從身份證書中獲取第三方審計人員的真實身份信息。

Abstract: In allusion to some privacy protection problems in the practical application of data audit system, such as data disclosure, data damage and the disclosure of the identity of third?party auditors, an elderly data audit system based on blockchain is designed, and on this basis, a supervised anonymous identity authentication scheme is designed. In this system, the asymmetric encryption algorithm and group signature algorithm are used to ensure the security of data communication and data storage, and achieve the anonymity of identity certificates, which has a certain ability of privacy protection. In addition, if the third?party auditors have illegal behavior, the true identity information of the third?party auditors can be obtained from the identity certificate.
Keywords: data auditing system; anonymous identity authentication; blockchain; elderly data; privacy protection; data communication

2021年,我國正式頒發《中華人民共和國數據安全法》,這表明國家高度重視數據安全領域。同時,數據安全也是國民經濟的重要保障[1],沒有數據安全就沒有我國經濟的高速發展。云計算與云存儲技術日益成熟,已經成功應用到我國的各行各業[2?4]。2024年1月,國際數據公司(IDC)發布調研報告表明,全國云計算與云存儲市場整體規模將達到154.3億元。僅2023年上半年,相關云服務的市場占比提升約26.6%。同時,相關外包云存儲市場規模將達到150.8億元,同比提升約25.8%。因此,越來越多的人開始關注云端數據的安全性問題[5?7]。2024年1月,國家統計局公布了我國2023年人口數據報告,表明近兩年我國人口持續負增長且人口老齡化嚴重[8]。這意味著接下來與老年數據存儲相關的云服務市場占比將有所提升[9?10]。
為了確保云服務平臺上數據的安全性和完整性,必須利用大數據、云計算和區塊鏈等技術構建一個有效的解決方案?!?br>
