Payment Block Bypass via Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cardholders face issues when trying to reinitiate transactions with merchants after previously requesting a payment block, as the block can prevent transactions from being completed even if the cardholder intends to re-subscribe or make a new purchase.
Innovation Solution
A payment network system that allows for the bypass and removal of user-requested blocks upon sufficient authentication of the transaction, enabling transactions to proceed despite the block and ensuring that the block is removed once the transaction is approved by the issuer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a payment block is placed to prevent improper charges, then cardholder security is improved, but legitimate transactions are declined
Solution Approach 1:
The patent introduces an intermediary authentication process between the block enforcement and transaction approval. When a transaction is attempted against a blocked merchant, the system inserts an authentication challenge that the cardholder must complete. This intermediary step allows the system to differentiate between fraudulent transactions (which should be blocked) and legitimate transactions (which should be allowed), thereby resolving the contradiction between security and ease of operation.
2Reliability
If a payment block is maintained to prevent recurring charges, then charge prevention is improved, but customer flexibility deteriorates
Solution Approach 1:
The patent makes the payment block dynamic rather than static. Instead of a fixed block that permanently prevents all transactions, the system dynamically evaluates each transaction attempt through authentication. The block adapts its enforcement level based on the authentication outcome: fully blocking fraudulent attempts while allowing legitimate ones. This dynamic approach resolves the contradiction between charge prevention and customer flexibility.
Solution Approach 2:
The system changes the parameter of block enforcement from a binary state (blocked/not blocked) to a multi-state system involving authentication levels. By introducing authentication as a variable parameter, the system can adjust the effective block strength based on the transaction context and customer verification, thereby maintaining charge prevention while restoring customer flexibility.
3Reliability
If authentication requirements are added to bypass blocks, then transaction security is improved, but processing complexity increases
Solution Approach 1:
The patent implements preliminary authentication actions that are prepared in advance and only activated when needed. The authentication mechanisms (such as biometric verification or one-time passwords) are pre-configured in the system but only invoked when a transaction attempts to bypass a payment block. This preliminary preparation reduces processing complexity during normal operations while maintaining high security when block bypass is required.

AI summary
This disclosure relates to a computer-implemented method for enabling a transaction bypass for a user-requested block on a merchant. The method involves receiving an authorization request message from a merchant, determining if the merchant is subject to an active block instruction, and verifying customer authentication information. If the authentication information is present and the merchant matches a block instruction, a transaction bypass message is generated and sent to the issuer. Based on the issuer's response, the active block may be removed or maintained. The method also allows for sending authentication data to the issuer for verification, and periodically receiving authorization requests from the merchant. Additional features include managing an authentication security threshold and sending status notifications to the merchant. The invention ensures secure transaction processing, providing flexible handling of user-requested merchant blocks based on customer authentication and issuer approval.
