WiMi Hologram Cloud, a global provider of Hologram Augmented Reality (AR) technology, has announced an IoT data perception system based on blockchain technology.
This system features decentralised storage, data verification, automated management driven by smart contracts, and secure data exchange enabled by cryptography. It allows data generated by IoT devices to be recorded directly on the blockchain, ensuring the authenticity and traceability of the data source, while using smart contracts to automatically enforce data transaction rules. This facilitates data sharing and maximises the value of data without compromising privacy.
The blockchain-based IoT data perception system enhances data security and privacy protection. By leveraging blockchain’s encryption technology and decentralised nature, it ensures the integrity and immutability of IoT data during transmission and storage. It improves the efficiency and transparency of data transactions and effectively defends against external attacks and internal fraud.
All transaction records are open, transparent, and traceable, increasing trust within the IoT ecosystem and facilitating multi-party collaboration. Smart contracts automatically execute data-sharing agreements, guaranteeing the security and compliance of data circulation, promoting cross-domain data sharing and collaboration, and addressing the issue of data silos. The system comprises multiple core technology modules that work together to create a highly secure, transparent, and efficient IoT data perception and management system, supporting cross-industry and cross-device data sharing and collaboration.
Key components include:
- Data Perception Collection: Responsible for gathering various types of data from IoT devices, such as environmental parameters, device status, and location information. This may involve diverse data collection devices like sensor networks, RFID tags, and cameras
- Blockchain Node: The system’s core component, used to store and validate data collected from sensing units. Each data block is encrypted and linked to the previous block, forming a tamper-proof chain that ensures data integrity and authenticity
- Smart Contracts: Automatically executable code deployed on the blockchain to define rules for data transactions, permission controls, and automatic responses to specific events, such as data-sharing agreements and payments
- Identity and Access Management: Manages the authentication of IoT devices and users to ensure that only authorised entities can access the system and interact with data, enhancing system security
- Locating and GPS Positioning: For applications requiring geographic location information, such as smart cities and logistics tracking, this module accurately locates IoT devices and assists in location-related data analysis and decision-making
- Data Analysis and Prediction: Utilises big data analysis and machine learning algorithms to process collected data, such as predicting traffic congestion or equipment failure, providing a basis for decision support
- Privacy Protection and Encryption: Employs advanced encryption technology to protect privacy during data transmission and storage, ensuring that personal or corporate data remains secure even when shared
