Core Account Transaction Verification Using Signed Time Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service account systems lack integrated verification of transaction legality and resource transfer-out processing, leading to potential security risks and inefficiencies in transaction verification.
Innovation Solution
A data processing method that includes transmitting transaction data with a data signature to a core account layer for signature and legality verification, using a transaction verification time range to ensure authenticity and legality, and associatively storing verified data in a core account database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transaction verification is performed independently from resource transfer-out processing, then verification simplicity is maintained, but security of the service account deteriorates
Solution Approach 1:
The patent merges transaction verification and resource transfer-out processing into a unified workflow. The core account layer simultaneously performs both verification of transaction legality (using the time range) and resource transfer processing, ensuring they are interdependent rather than independent. This integration prevents unauthorized resource transfers while maintaining a streamlined verification process.
2Reliability
If all transactions are verified during subsequent transaction verification, then verification completeness is achieved, but verification efficiency deteriorates due to lengthy evidencing chain
Solution Approach 1:
The patent implements preliminary verification by embedding the transaction verification time range directly into the transaction data before it reaches the core account layer. This time range serves as pre-computed verification criteria that enables the core account layer to quickly determine transaction legality without constructing lengthy evidencing chains during subsequent verification processes.
3Measurement precision
If transaction verification time range is embedded in transaction data, then verification accuracy is improved, but data structure complexity increases
Solution Approach 1:
The patent applies local quality by adding the transaction verification time range as a specific attribute within the transaction data structure. Rather than redesigning the entire data structure, the time range is embedded as a localized verification criterion that provides precise verification capability while maintaining the overall simplicity of the existing transaction data framework.
Data Source
AI summary
A data processing method includes transmitting, at a moment, transaction data initiated by a service account to a core account layer. The transaction data includes a service transaction and a transaction verification time range corresponding to the service transaction, and the transaction data carries a data signature. The method further includes performing, in the core account layer, signature verification on the data signature, performing, in response to the signature verification being successful, legality verification on the service transaction according to the moment and the transaction verification time range, and associatively storing, in response to the service transaction being legal, the moment and the transaction data in a core account database corresponding to the core account layer.
