Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for presenting trusted data are cumbersome and inconvenient, requiring users to repeatedly obtain data from authority agencies and lack traceability in data usage.
Innovation Solution
A data processing method and apparatus that involves obtaining and verifying data use authorization information, storing trusted data in hardware, and recording data transactions on a blockchain network to ensure data integrity and facilitate user-friendly management and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users repeatedly obtain data from authority agencies with official seals, then data trustworthiness is ensured, but operation convenience deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-storing trusted data in trusted hardware devices (such as USB security tokens) before users need it. Users obtain trusted data once and store it in advance, eliminating the need to repeatedly visit authority agencies. The data is stored in a secure, tamper-resistant manner with associated authorization information that enables future use without re-obtaining.
Solution Approach 2:
The patent uses copying by creating digital copies of trusted data and storing them in trusted hardware devices. Instead of requiring physical presence at authority agencies, the system creates authorized copies that can be stored and reused. Blockchain technology records these copies and their authorization status, ensuring authenticity while enabling convenient access.
2Loss of information
If data is stored in trusted hardware with blockchain recording, then data usage traceability is improved, but device complexity increases
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between trusted hardware devices and the data usage tracking system. The blockchain serves as a decentralized ledger that records data usage events, authorization information, and transaction details without requiring complex centralized tracking infrastructure. This intermediary simplifies the overall system architecture while providing comprehensive traceability.
3Reliability
If users present data from authority agencies, then service provision reliability is improved, but time consumption increases
Solution Approach 1:
The patent enables users to perform preliminary actions by obtaining and storing trusted data in advance in trusted hardware devices. Instead of spending time repeatedly visiting authority agencies whenever data is needed, users can access their pre-stored trusted data instantly. The system verifies data authenticity through blockchain records and authorization information, maintaining service provision reliability while dramatically reducing time consumption.

AI summary
Embodiments of the present specification disclose a data processing method, apparatus, and device. A solution can include: verifying data use authorization information sent by a data requester; sending data authorized to be accessed by the data use authorization information stored in trusted hardware to the data requester if the verification is successful, where because the data stored in the trusted hardware is data obtained from a trusted institution and the data in the trusted hardware cannot be tampered with, the data sent to the data requester can be ensured to be trusted data; and storing a data sending record for the data in a blockchain network.
