Abstract: Aiming at the problem that multi-source network data has a low security factor during transmission and cannot guarantee the security of user information, research on multi-source network data privacy protection is carried out, and a multi-source network data privacy protection method based on blockchain technology is proposed. By detecting whether malicious nodes are generated during the transmission of multi-source network data, the uniqueness of blockchain technology is used to protect data privacy. Experiments show that this method can effectively improve the security factor of data transmission compared with traditional methods, and provide effective guarantee for the trust and privacy of multi-source network nodes.

摘要： 针对多源网络数据在传输过程中安全系数较低，无法保证用户信息的安全问题，开展多源网络数据隐私保护的研究，提出一种基于区块链技术的多源网络数据隐私保护方法。通过对多源网络数据在传输过程中是否产生恶意节点进行检测，再利用区块链技术的独特性对数据隐私进行保护。通过实验证明，该方法与传统方法相比有效提高了数据传输的安全系数，为多源网络节点的信任和隐私提供有效保障。
