WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global provider of holographic augmented reality (AR) technology, announced the development of a blockchain-based privacy and security protection framework. The framework is designed to leverage the decentralization, transparency and immutability of blockchain technology to facilitate secure data sharing and collaboration within smart cities. It aims to integrate various advanced encryption and authentication technologies and establish a secure and efficient ecosystem for Internet of Things (IoT) data.
Secure Initialization and Authentication
A blockchain-based framework begins by creating a decentralized network through a secure initialization process that includes rigorous authentication and registration of all participating IoT devices and users. A Public Key Infrastructure (PKI) is used to issue digital certificates, ensuring the authenticity and legitimacy of each participant. This foundational step is essential to establish trust for all subsequent data exchanges within the network.
Multi-layer encryption for data protection
To protect data, the framework employs a multi-layer encryption strategy. Data is encrypted at the time of generation, and symmetric encryption algorithms such as AES ensure confidentiality both in transit and at rest. Additionally, asymmetric encryption techniques such as RSA are used for key exchange to further strengthen security. Data hashing is implemented to maintain data integrity and allow for rapid detection of unauthorized modifications.
Robust Access Control Mechanisms
The framework also incorporates strict access control mechanisms to ensure that only authorized users can access data. These mechanisms include role-based access control and fine-grained attribute-based access control, which dynamically adjusts access rights based on user roles, attributes, and contextual conditions. One-time passwords are introduced to enhance security during the login and transaction process, effectively preventing replay attacks and unauthorized access attempts.
A comprehensive solution for IoT data security
WiMi’s blockchain-based privacy and security protection framework provides a comprehensive solution for secure IoT data sharing in smart cities. The framework combines blockchain technology with advanced encryption methods to address the security vulnerabilities inherent in traditional centralized repositories, ensuring secure data transmission, storage and access control, laying a solid foundation for the sustainable development of smart cities.
Future prospects and application development
WiMi expects that the role of this blockchain-based privacy and security protection framework will become even stronger in the future as the technology continues to mature and its application scenarios expand. The company hopes that the framework will play a key role in improving security standards and enhancing data collaboration within smart cities.
Key features of the WiMi framework
Building a decentralized network
A secure initialization process forms the foundation of the framework, with all IoT devices and users undergoing rigorous authentication and registration, facilitated by a PKI, establishing the network of trust essential for secure data exchange.
Advanced encryption technology
The framework’s multi-layer encryption strategy ensures that your data remains confidential and secure at every stage: Symmetric encryption algorithms protect data in transit and at rest, while asymmetric encryption techniques secure key exchanges. Data hashing ensures integrity and any unauthorized modifications are immediately detected.
Dynamic Access Control
Integration of role- and attribute-based access control mechanisms dynamically adjusts access rights to ensure that only authorized users can access data. The inclusion of one-time passwords enhances login and transaction security, preventing unauthorized access attempts.
Integration and Future Applications
WiMi’s framework not only addresses current security challenges, but also paves the way for future advancements in smart city technology. The combination of blockchain and encryption technologies provides a scalable solution that can adapt to the evolving needs of smart cities, facilitating higher security standards and deeper data collaboration.
Conclusion
WiMi Hologram Cloud’s blockchain-based privacy and security protection framework represents a major advancement in the secure management of IoT data within smart cities. By addressing the limitations of traditional centralized systems and providing robust encryption and access control mechanisms, this innovative solution establishes a new benchmark for smart city governance and data integrity. As technology continues to evolve, WiMi’s framework is poised to play a pivotal role in shaping the future of safe, efficient and collaborative urban environments.
