Recent advances in information technology go beyond the simple convenience offered to individuals, leading to smart city technology that provides urban facilities and better quality of life. Smart City is a heterogeneous system consisting of a large IoT-based network, offering various applications for citizens by collecting and analyzing real-time information. As intelligent, efficient digital systems, smart cities manage data by digitalizing all information. Despite the potential benefits of smart cities for citizen convenience, this digital information service can give rise to security and privacy issues. In particular, the challenge of relying on the Cloud Service Provider (CSP) is that it is difficult for individuals to manage large amounts of data in smart city environments. In this paper, we study blockchain and Secret Sharing to address personal information protection issues in external cloud services and improve data integrity and security by designing a distributed system. CSPs are connected in a blockchain to validate user data integrity and provide easy data access through Transaction. CSP uses the blockchain to store distributed users' information safely through the Secret Sharing algorithm as a distributed system with improved security of existing centralized systems. The proposed approach demonstrates improved security and privacy through security analysis and has faster transaction speed and data storage efficiency than existing research.

基于区块链的基于云秘密共享的智慧城市云架构

信息技术的最新进展已经超越了为个人提供的简单便利,从而导致了提供城市设施和更高生活质量的智能城市技术。智能城市是一个异构系统,由基于物联网的大型网络组成,通过收集和分析实时信息为市民提供各种应用程序。作为智能,高效的数字系统,智慧城市通过数字化所有信息来管理数据。尽管智能城市可能为市民带来便利,但这种数字信息服务仍会引起安全和隐私问题。特别是,依靠云服务提供商(CSP)的挑战在于,个人很难在智慧城市环境中管理大量数据。在本文中,我们研究了区块链和秘密共享,以解决外部云服务中的个人信息保护问题,并通过设计分布式系统来改善数据完整性和安全性。CSP连接在区块链中,以验证用户数据的完整性,并通过Transaction提供便捷的数据访问。CSP使用区块链通过秘密共享算法将分布式用户的信息安全地存储为分布式系统,从而提高了现有集中式系统的安全性。所提出的方法通过安全性分析证明了改进的安全性和隐私性,并且比现有研究具有更快的事务处理速度和数据存储效率。CSP连接在区块链中,以验证用户数据的完整性,并通过Transaction提供便捷的数据访问。CSP使用区块链通过秘密共享算法将分布式用户的信息安全地存储为分布式系统,从而提高了现有集中式系统的安全性。所提出的方法通过安全性分析证明了改进的安全性和隐私性,并且比现有研究具有更快的事务处理速度和数据存储效率。CSP连接在区块链中,以验证用户数据的完整性,并通过Transaction提供便捷的数据访问。CSP使用区块链通过秘密共享算法将分布式用户的信息安全地存储为分布式系统,从而提高了现有集中式系统的安全性。所提出的方法通过安全性分析证明了改进的安全性和隐私性,并且比现有研究具有更快的事务处理速度和数据存储效率。
