WiMi Announces Blockchain-Based Framework for Secure Data Sharing in Smart Cities
WiMi Hologram Cloud Inc. today announced a blockchain-based privacy security protection framework that will provide an innovative solution for secure data sharing and collaboration in smart cities. The solution not only integrates the advantages of decentralization, transparency and immutability of blockchain technology, but also deeply integrates a variety of advanced encryption and authentication technologies, aiming to establish a secure and efficient sharing ecosystem for IoT data in smart cities, and to ensure the security and integrity of IoT data.
In the blockchain-based privacy and security protection framework, a decentralized network is first created through a secure initialization process in which all participating IoT devices and users undergo rigorous authentication and registration procedures. This process uses public key infrastructure (PKI) to issue digital certificates to ensure the authenticity and legitimacy of each participant, laying the foundation of trust for subsequent data exchanges.
In terms of data protection, the blockchain-based privacy and security protection framework employs a multi-layer encryption strategy. Data is encrypted when generated, and symmetric encryption algorithms such as AES are used to ensure the confidentiality of data in transit and at rest. Meanwhile, asymmetric encryption techniques (e.g., RSA) are used for key exchange to further enhance data security. In addition, data hash processing ensures data integrity, and any unauthorized changes to data can be quickly detected.
In addition, to ensure that only authorized users can access the data, the blockchain-based privacy and security protection framework implements strict access control mechanisms. This includes role-based access control and fine-grained attribute-based access control, which allows the system to dynamically adjust access rights based on users’ roles, attributes, and contextual conditions. In addition, the introduction of one-time passwords strengthens the security of login and transaction processes, effectively preventing replay attacks and unauthorized access attempts.
WiMi’s blockchain-based privacy security protection framework provides a comprehensive and innovative solution for secure IoT data sharing in smart cities. It not only solves the security vulnerabilities of traditional centralized repositories, but also realizes secure data transmission, storage and access control by combining blockchain and advanced encryption technologies, laying a solid foundation for the sustainable development of smart cities. In the future, with the continuous maturity of technology and the expansion of application scenarios, it is expected that the blockchain-based privacy security protection framework will become important to push smart cities towards higher security standards and deeper data collaboration.
