Visual Voucher Communication System for Fraud-Resistant Transit Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual voucher systems in mass transit and controlled access events are vulnerable to fraud due to replicable images and rely on unpredictable wireless service for updates, making it challenging to ensure validity and efficiency.
Innovation Solution
A visual voucher communication system using Entry Point Devices connected to two-way beacon devices or Wi-Fi routers, which transmit current voucher data to mobile devices, ensuring only authorized users receive updates, and allowing for frequent image changes to mitigate fraud.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional barcode scanning is used for ticket validation, then automated verification is achieved, but it is not practical for multiple entry points where manual inspection is needed
Solution Approach 1:
The patent replaces traditional barcode scanning equipment with visual symbols that can be manually inspected by transit personnel. The mechanical/optical scanning system is substituted with human visual verification of simplified graphical symbols, making the system adaptable to multiple entry points without requiring complex automated scanning infrastructure at each location.
2Reliability
If voucher images are made unique to date, time, and route to prevent fraud, then security is improved, but reliable deployment is challenged by spotty wireless service
Solution Approach 1:
The system pre-generates and stores multiple unique voucher symbols locally on transit personnel devices before wireless service is available. These pre-prepared symbols correspond to different dates, times, and routes, allowing immediate validation without requiring real-time wireless downloads, thus overcoming spotty service conditions.
Solution Approach 2:
The voucher symbols incorporate multiple variable parameters including date, time, route, and sequence numbers. By changing these parameters, each voucher becomes unique and time-sensitive, preventing fraud while the local storage capability ensures reliable deployment regardless of wireless service availability.
3Reliability
If voucher images are frequently changed to mitigate fraud, then security is improved, but communicating current images to drivers becomes more challenging
Solution Approach 1:
Transit personnel devices pre-load multiple future voucher symbols and validation rules before needed. This advance preparation eliminates the need for real-time communication during frequent voucher changes, allowing drivers to immediately validate current vouchers without waiting for image updates to be transmitted.
Solution Approach 2:
The voucher system divides validation information into separate components: symbolic visual elements, validation rules, and current active voucher identification. This segmentation allows the system to communicate only necessary update information rather than complete image sets, reducing communication time while maintaining security through frequent changes.
4Ease of operation
If visual symbols are used instead of barcodes for manual inspection, then ease of use at multiple entry points is improved, but vulnerability to replication and fraud increases
Solution Approach 1:
The visual voucher symbols use asymmetric, non-replicable graphical patterns that are difficult to copy accurately. The symbols incorporate unique geometric arrangements and visual characteristics that make fraudulent replication obvious to trained inspectors, maintaining ease of visual inspection while significantly reducing fraud vulnerability compared to simple barcodes or symmetric patterns.
Data Source
AI summary
Various embodiments each include at least one of systems, devices, methods, and software for visual voucher communication systems and methods. One such embodiment includes receiving an entry request with an account identifier from a requestor and retrieving data of a voucher from a voucher database based on the account identifier and a current voucher requirement. In such embodiments, when voucher data is retrieved, the voucher data is transmitted to the requestor. However, when no voucher data is retrieved and at least one voucher is available, the method includes transmitting a voucher procurement option to the requestor. Otherwise, when no voucher data is retrieved and no voucher is available, data representative thereof is transmitted to the requestor.
