Intermediary Payment System for Secure E-commerce Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-commerce systems lack security and reliability in transactions, as buyers may not receive goods as described, and sensitive payment information is vulnerable, with difficulties in proving receipt or satisfaction of purchases.
Innovation Solution
A system and method that involves an intermediary to hold payment until both the buyer and seller confirm delivery and satisfaction, using signals to verify the transaction and release funds only if conditions are met, incorporating modules for order verification and payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buyer pays the seller directly, then the transaction process is simple, but the buyer's payment information is vulnerable and there is no guarantee of receiving goods as described
Solution Approach 1:
The patent introduces an intermediary system (payment processing system) that acts as a mediator between buyer and seller. The system holds payment information in escrow, verifies transaction completion through signal matching, and releases funds only when conditions are met. This resolves the contradiction by adding an intermediary layer that enhances security without significantly complicating the user experience.
Solution Approach 2:
The system performs preliminary actions by capturing and holding payment information before the transaction is complete. The payment is authorized and held in the intermediary system prior to delivery verification, ensuring funds are secured while protecting the buyer from premature exposure of sensitive payment details to the seller.
2Reliability
If the buyer receives goods without verification, then the transaction is fast, but the buyer may not receive goods as described or may be unable to prove receipt
Solution Approach 1:
The system performs preliminary synchronization of authorization signals between the buyer's device and the intermediary system before the transaction occurs. This pre-established cryptographic verification mechanism allows for rapid verification of receipt and satisfaction without time-consuming manual processes, resolving the contradiction between verification reliability and transaction speed.
Solution Approach 2:
The patent replaces traditional mechanical verification methods (manual inspection, physical signatures, paper receipts) with electronic signal-based verification. The synchronization of authorization signals provides cryptographic proof of transaction completion, enabling fast automated verification that maintains reliability while minimizing time loss.
3Reliability
If the seller handles payment information, then the payment process is direct, but the seller may mischarge or compromise buyer's sensitive information
Solution Approach 1:
The intermediary payment system acts as a trusted mediator that handles all sensitive payment information processing. The seller never receives or processes the buyer's actual payment details - only authorization tokens and verification signals are exchanged. This resolves the contradiction by removing the seller from the payment information handling chain while maintaining simple payment processing for both parties.
Solution Approach 2:
The patent extracts the sensitive payment information handling function from the seller's system and places it exclusively in the intermediary payment system. The seller's system only handles non-sensitive transaction coordination, while all payment data processing occurs in the secure intermediary environment, eliminating the risk of seller-side information compromise.

AI summary
A method for managing an e-commerce system comprising: accepting an order to sell one or more goods or services from a seller to a buyer; charging the buyer an amount according to the order; holding the amount in an intermediary; receiving a first signal from the buyer upon the seller's delivery of said one or more goods or services; retrieving a second signal; verifying the first signal against the second signal; and making at least a portion of the amount available to the seller if the first signal and the second signal satisfy a predetermined relationship.
