Secure Anonymous Transaction System Using One-Time Card Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic commerce systems lack secure and anonymous transaction methods, exposing users to potential fraud and privacy violations, as they often require sharing personal information during transactions.
Innovation Solution
The Secure Anonymous Transaction (SAT) system employs a custom hardware authentication chip and a pay network server to generate one-time anonymous cards, anonymize user information, and provide real-time transaction notifications, ensuring secure and private transactions by shielding user data from merchants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electronic commerce transaction methods are used, then transaction processing is simple and direct, but user privacy is compromised and fraud risk increases due to exposure of personal information
Solution Approach 1:
The patent introduces a payment network server as an intermediary between the user and the merchant. This server generates one-time anonymous card numbers and transmits transaction data anonymously, preventing the merchant from accessing the user's personal information while still enabling successful transactions. The intermediary shields the user's identifying information from the merchant throughout the transaction process.
Solution Approach 2:
The system creates a copy of the user's payment information in the form of a one-time anonymous card number. This copy contains sufficient data to process the transaction but excludes sensitive personal identifying information. The anonymous card copy is transmitted to the merchant instead of the user's actual card information, enabling transaction processing while protecting privacy.
2Loss of information
If one-time anonymous cards are generated and transmitted, then user privacy is protected, but transaction processing time and system complexity increase
Solution Approach 1:
The payment network server generates the one-time anonymous card number and transmits the anonymous transaction data to the merchant before the actual purchase is completed. This preliminary action ensures that privacy protection is established in advance, and the merchant receives ready-to-use anonymous transaction information without delays during the checkout process.
Solution Approach 2:
The system automatically generates one-time anonymous card numbers and transmits encrypted transaction data without requiring manual intervention. The payment network server handles the entire process of creating anonymous identifiers and securing data transmission autonomously, minimizing additional time requirements beyond standard transaction processing.
3Object-affected harmful factors
If authentication chip is required for transactions, then fraud prevention is enhanced, but ease of operation is reduced
Solution Approach 1:
The authentication chip functionality is merged with the mobile communication device, combining security authentication with an everyday carried device. The chip is integrated into the mobile phone that users already possess and use constantly, eliminating the need for separate authentication devices while maintaining security.
Solution Approach 2:
The authentication chip automatically performs fraud prevention functions without requiring active user intervention. The chip verifies transaction authenticity and protects against fraud autonomously during the transaction process, providing security enhancement without adding operational steps or complexity for the user.

AI summary
The SECURE ANONYMOUS TRANSACTION APPARATUSES, METHODS AND SYSTEMS (“SAT”) transform hardware-verified user authentication requests via SAT components into secure transaction notifications. In one implementation, the SAT obtains a secure anonymous transaction user authentication request. The SAT verifies the authenticity of a user, using the secure anonymous transaction user authentication request. The SAT obtains an authenticated purchase order, in response to which it generates a one-time anonymous card account. Using the one-time card account, the SAT generates an anonymized purchase order for a merchant, and provides the anonymized purchase order. On obtaining a purchase notification for the anonymized purchase order, the SAT provides a real-time notification for a user of the purchase notification. Also, on obtaining notification of a shipment related to the anonymized purchase order to an anonymized address, the SAT generates an order to re-route the shipment from the anonymized address to an actual shipment address of the user.
