Proximity-Based Secure Transaction Authorization System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems lack a convenient and secure method for authorizing transactions between devices in proximity, particularly for financial and physical access operations, which often require manual input or separate identification.
Innovation Solution
A communications system that enables mobile wireless devices to determine proximity and generate secure transaction requests, allowing for secure transactions to be performed by a transaction terminal when devices are paired via NFC or Bluetooth, leveraging proximity-based authorization for enhanced security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input or separate identification methods are used for transaction authorization, then security can be maintained, but convenience and speed of transaction are reduced
Solution Approach 1:
The system performs preliminary pairing and authorization between mobile devices before the actual transaction occurs. When devices are paired via NFC or Bluetooth, the authorization relationship is established in advance, so that during the transaction no additional manual input or identification steps are needed, thus improving convenience and speed while maintaining security
2Productivity
If proximity-based pairing and authorization is implemented, then transaction speed and convenience are improved, but system complexity increases
Solution Approach 1:
The system uses universal wireless communication standards (NFC and Bluetooth) that are already widely integrated into mobile devices. By leveraging these existing multi-functional communication capabilities, the system achieves proximity-based authorization without requiring specialized hardware or complex proprietary protocols, thus limiting the increase in system complexity
3Ease of operation
If proximity-based authorization is used, then convenience is improved, but security requirements become more stringent
Solution Approach 1:
The system introduces a transaction terminal as an intermediary that verifies and validates the proximity-based authorization between mobile devices. The terminal acts as a trusted mediator that confirms the authorization relationship before completing the transaction, thereby enhancing security assurance while maintaining the convenience of proximity-based operation

AI summary
A communications system may include a plurality of mobile wireless communications devices configured to determine proximity between one another. At least one of the mobile wireless communications devices may also be configured to generate a secure transaction request based upon the determined proximity. The system may further include a transaction terminal configured to receive the secure transaction request and perform a secure transaction based thereon.
