WiMi Hologram Cloud Inc. today launched a blockchain-based privacy and security protection framework that provides an innovative solution for secure data sharing and collaboration in smart cities. The solution not only integrates the decentralization, transparency and immutability advantages of blockchain technology, but also deeply integrates various advanced encryption and authentication technologies, aiming to establish a safe and efficient smart city IoT data sharing ecosystem and ensure the security and integrity of IoT data.
In a blockchain-based privacy and security framework, a decentralized network is first created through a secure initialization process, where all participating IoT devices and users are subject to rigorous authentication and registration, using 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 at the time of generation and uses symmetric encryption algorithms such as AES to ensure 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. Moreover, data hashing ensures data integrity and quickly detects unauthorized changes to the data.
Moreover, to ensure that only authorized users can access data, the blockchain-based privacy and security protection framework implements strict access control mechanisms, including role-based access control and fine-grained attribute-based access control, allowing the system to dynamically adjust access rights based on user roles, attributes and contextual conditions. Moreover, the introduction of one-time passwords enhances 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 the secure sharing of IoT data in smart cities. Not only does it solve the security vulnerabilities of traditional centralized repositories, but the combination of blockchain and advanced encryption technology also enables secure data transmission, storage and access control, laying a solid foundation for the sustainable development of smart cities. In the future, with the continued maturity of technology and the expansion of application scenarios, the blockchain-based privacy security protection framework is expected to play a key role in driving smart cities towards higher security standards and deeper data collaboration.
