USER DATA MANAGEMENT METHOD AND RELATED DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18514095 titled 'USER DATA MANAGEMENT METHOD AND RELATED DEVICE
Simplified Explanation
Embodiments of this application provide a user data management method and a related device, to improve user data security. The method includes: A data request device sends a first request to a blockchain platform, where the first request indicates that the data request device needs to access a data storage device. The data request device receives first permission information sent by the blockchain platform, where the first permission information indicates whether the data request device has permission to access the data storage device, and the permission is related to signature information of the data request device, an access type, and an operator public key; and sends a second request to the data storage device if the first permission information indicates that the data request device has the permission to access the data storage device, where the second request includes an access address and an operator private key signature.
- Data request device sends a request to blockchain platform for access to data storage device
- Blockchain platform provides permission information based on signature, access type, and operator public key
- Data request device sends second request to data storage device with access address and operator private key signature
Potential Applications
This technology could be applied in secure data management systems, access control systems, and blockchain-based data storage solutions.
Problems Solved
This technology solves the problem of unauthorized access to sensitive user data, improves data security, and enhances data access control mechanisms.
Benefits
The benefits of this technology include enhanced user data security, improved access control, and increased trust in data management systems.
Potential Commercial Applications
Secure Data Access Management System: Enhancing data security through blockchain technology.
