Authentication Metadata in Payment Transaction Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction protocols lack support for modern authentication techniques, leading to increased development costs and complexity for merchants and banks, and do not effectively mitigate fraud risks in digital transactions.
Innovation Solution
Integration of authentication metadata into transaction authorization protocols, using biometric authentication methods such as fingerprint, facial, and vocal recognition, to verify user identity and reduce fraud risk by providing authentication metadata that includes success rates and other statistical metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If modern authentication techniques are implemented, then transaction security is improved, but development cost and system complexity increase
Solution Approach 1:
The patent introduces authentication metadata as an intermediary element that bridges traditional transaction protocols and modern authentication techniques. This metadata structure allows authentication information to be transmitted through existing protocol frameworks without requiring fundamental protocol changes, thereby reducing development complexity while enabling enhanced security through biometric and other modern authentication methods
Solution Approach 2:
The authentication metadata structure is designed to be universal and protocol-agnostic, capable of carrying various types of authentication information (biometric, device-based, behavioral) across different transaction protocols. This multi-functionality allows a single metadata framework to support multiple authentication techniques simultaneously, reducing overall system complexity while maintaining high security standards
2Device complexity
If traditional transaction protocols are used, then system simplicity is maintained, but fraud mitigation capability is insufficient
Solution Approach 1:
The patent segments the authentication process from the transaction protocol by introducing a separate authentication metadata structure. This segmentation allows traditional protocols to remain simple and unchanged while authentication capabilities are independently enhanced through the metadata layer, which carries authentication results and risk indicators separately from the core transaction flow
3Reliability
If authentication metadata is integrated into transaction protocols, then fraud risk is reduced, but protocol complexity increases
Solution Approach 1:
The patent creates a simplified copy or representation of authentication information through metadata statements that capture essential authentication outcomes without requiring transmission of complex raw authentication data. This metadata copying approach reduces protocol complexity by transmitting only the necessary authentication verification results rather than complete authentication datasets
Data Source
AI summary
A system may receive a transaction request for a transaction using a transaction authorization protocol. The transaction request may include a transaction amount and may also be associated with a transaction account. The system may transmit a request to authenticate a user associated with the transaction account. The request to authenticate uses the transaction authorization protocol. The system may also receive an authentication message using the transaction authorization protocol. The authentication message may comprise authentication metadata that indicates an authentication type and/or an authentication outcome. The authentication type may include biometric authentication techniques.
