WiMi said the aim is to establish a sharing ecosystem for IoT data in smart cities that is secure and efficient and ensures IoT data security and integrity.
Hologram augmented reality (AR) technology provider WiMi Hologram Cloud is launching a blockchain-based privacy security protection framework for secure data sharing and collaboration in smart cities.
As well as integrating the advantages of decentralisation, transparency, and immutability of blockchain technology it also incorporates a variety of advanced encryption and authentication technologies.
IoT data-sharing ecosystem
WiMi said the aim of the platform is to establish a sharing ecosystem for Internet of Things (IoT) data in smart cities that is both secure and efficient, and that also ensures IoT data security and integrity.
In the blockchain-based privacy and security protection framework, a decentralised network is first created through a secure initialisation process where all participating IoT devices and users are subject to strict authentication and registration.
This process uses public key infrastructure (PKI) to issue digital certificates to ensure the authenticity and legitimacy of each participant, laying a foundation of trust for subsequent data exchanges.
In terms of data protection, the blockchain-based privacy and security protection framework employs a multi-layered encryption strategy. Data is encrypted when it is generated, and symmetric encryption algorithms such as advanced encryption standards (AES) are used to ensure data confidentiality in transit and at rest.
Meanwhile, asymmetric encryption techniques are used for key exchange to further enhance data security. In addition, data hash processing ensures data integrity and any unauthorised modifications to the data can be quickly detected.
To ensure that only authorised users can access the data, the blockchain-based privacy and security protection framework implements strict access control mechanisms. This includes role-based access control as well as 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 the login and transaction processes, effectively preventing replay attacks and unauthorised access attempts.
WiMi claims the platform not only solves the security vulnerabilities of traditional centralised repositories, but also realises 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.
