区块链技术在信息技术安全与隐私保护中的应用

随着网络和移动设备用户数量的增长，信息安全和隐私保护变得越来越重要。文中提出了一种基于区块链的解决方案，即隐私保护型区块链系统，以保护用户数据的安全性和隐私性。此外，设计并实施了一种利用区块链不可篡改性和分布式特性的系统，以确保数据的完整性和防止未经授权的访问。通过仿真实验，验证了该系统的有效性和效率。实验结果表明，该系统在提高用户数据安全性和隐私性方面表现优异，是一种值得推广的新型数据保护策略。

Application of Blockchain Technology in Information Technology Security and Privacy Protection

With the growth of network and mobile device users, information security and privacy protection have become increasingly important. This paper proposes a blockchain based solution, namely a privacy protected blockchain system, to protect the security and privacy of user data.In addition, a system utilizing the immutability and distributed nature of blockchain has been designed and implemented to ensure data integrity and prevent unauthorized access. The effectiveness and efficiency of the system were verified through simulation experiments. The experimental results show that the system performs excellently in improving user data security and privacy, and is a new data protection strategy worth promoting.
