Solution Overview

Problem

Users are concerned about the security of using mobile wireless communications devices for payment processing systems, as they carry sensitive account information, leading to a need for enhanced security measures.

Innovation Solution

A payment processing system that includes a mobile wireless communications device, a point-of-sale (POS) device, and a secure intermediary, which uses a unique POS identifier encoded in a coded image to facilitate secure transactions by routing communications through a relay network, ensuring encrypted and secure data transmission between devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile wireless communications devices are used to store account access information for payment processing, then the number of cards carried by users is reduced, but security concerns increase due to the sensitivity of the stored information

Engineering Contradiction:

Improvecard consolidation capabilityVSAvoidsecurity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

A relay network is introduced as an intermediary component between the mobile device and the payment processing system. The relay network receives account access information from the mobile device, processes it securely, and forwards it to the payment processing system, thereby isolating the mobile device from direct exposure to security risks while maintaining payment functionality

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The payment processing system is segmented into distinct functional components: the mobile device that stores account information, the relay network that handles secure communication, and the payment processing system that executes transactions. This segmentation allows each component to be optimized for its specific function while reducing the security attack surface

Inventive Principle:

Principle #1Segmentation

2Reliability

If a relay network is used to route communications securely, then security is enhanced, but device complexity and communication overhead increase

Engineering Contradiction:

ImprovesecurityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The relay network is designed to handle multiple functions including secure communication routing, authentication verification, and transaction coordination through a single unified platform, reducing the need for separate specialized components and minimizing overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

In a payment processing system, a secure intermediary system associates payment processing devices including a POS device, mobile communication device, and transaction server with unique identifiers. The secure intermediary receives communications of transaction data from the payment processing devices, the communications including identifiers. The secure intermediary uses the unique identifiers to determine network addresses for the recipients of transaction data in support of a transaction.
