Token Metadata Mediation for Cross-Network Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incompatibilities between different processing network computers can lead to incomplete interactions and processing errors when using access tokens, requiring additional steps to rectify errors.
Innovation Solution
A record server computer retrieves and provides metadata to processing network computers using tokens and device/session identifiers, enabling compatibility and proper transaction processing across different network systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a token is used with an incompatible processing network computer, then processing errors occur and interactions cannot be completed, but adding compatibility processing steps increases system complexity
Solution Approach 1:
The patent introduces a metadata server as an intermediary component that stores and provides metadata about tokens to processing network computers. When a processing network computer receives a token, it queries the metadata server to obtain compatibility information and processing parameters. This mediator enables incompatible tokens to be processed correctly without requiring complex compatibility processing steps at each processing node, thus resolving the contradiction between adaptability and system complexity.
2Reliability
If additional processing steps are added to rectify errors from incompatible tokens, then transaction accuracy improves, but processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-storing metadata information about tokens in the metadata server during token issuance. This metadata includes compatibility information, processing parameters, and validation rules. When a token needs to be processed, the processing network computer simply queries the pre-prepared metadata rather than performing complex error detection and rectification steps. This eliminates the need for additional processing steps during transaction execution, maintaining both high transaction accuracy and fast processing speed.
3Reliability
If metadata retrieval is implemented across distributed processing network computers, then token processing reliability improves, but network communication overhead increases
Solution Approach 1:
The patent extracts critical token information (metadata) from the token issuance system and stores it separately in a dedicated metadata server. This extracted metadata contains all necessary compatibility and processing information that would otherwise need to be transmitted during each transaction. By taking out this information beforehand and making it readily accessible, the system achieves reliable token processing across distributed computers without incurring significant network communication overhead during actual transactions.
Data Source
AI summary
A method is disclosed and includes receiving, by a record server computer from a first processing network computer, a token, a device identifier associated with a user device, a session identifier associated with a registration request, and metadata about the token, and then receiving a metadata request from a second processing network computer in response to the second processing network computer receiving an authorization request message comprising the token, and the device identifier and/or the session identifier. The metadata request comprises at least the device identifier and/or the session identifier. The method also includes retrieving, by the record server computer, metadata associated with the metadata request, and providing the metadata to the second processing network computer. The second processing network computer processes the authorization request message using the token and the metadata.
