区块链技术在数据溯源中的应用研究
摘 要
随着信息技术的快速发展，数据溯源在保障数据真实性、提升供应链透明度和维护信息安全等方面的重要性日益凸显。然而，传统数据溯源方法面临数据篡改风险高、信任机制薄弱以及跨组织协作效率低等问题，难以满足现代复杂场景的需求。为解决上述问题，本研究以区块链技术为核心，探索其在数据溯源中的应用潜力。研究旨在通过构建基于区块链的数据溯源框架，实现数据全生命周期的可信记录与高效追踪。具体而言，研究采用智能合约技术确保数据操作的自动化与透明性，并结合分布式账本技术保障数据不可篡改性。同时，引入隐私保护算法以平衡数据共享与安全性之间的矛盾。实验结果表明，所提出的框架能够显著提高数据溯源的准确性和效率，降低系统对中心化机构的依赖，从而增强整体系统的可信度。

Abstract
With the rapid development of information technology, data traceability is becoming increasingly important in ensuring data authenticity, improving the transparency of supply chain and maintaining information security. However, traditional data traceability methods are faced with the problems of high risk of data tampering, weak trust mechanism and low efficiency of cross-organization collaboration, which is difficult to meet the needs of modern complex scenarios. In order to solve the above problems, this research takes blockchain technology as the core to explore its application potential in data traceability. The research aims to achieve a trusted record and efficient tracking of the whole life cycle of data by building a data traceability fr amework based on blockchain. Specifically, the study uses smart contract technology to ensure the automation and transparency of data operations, and combines distributed ledger technology to ensure data immutability. At the same time, the privacy protection algorithm is introduced to balance the contradiction between data sharing and security. The experimental results show that the proposed fr amework can significantly improve the accuracy and efficiency of data traceability, reduce the dependence of the system on the centralized mechanism, and thus enhance the credibility of the overall system.
