Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth validation in public transportation systems is vulnerable to fraud possibilities such as ticket sharing, cloning, and device spoofing, which can lead to revenue losses and overcrowding, necessitating additional security measures to ensure authorized access.
Innovation Solution
Implementing a multi-factor authentication system using High Frequency Data-over-Voice (HF DOV) technology in conjunction with Bluetooth validation, where both Bluetooth and audio signals are synchronously authenticated, enhancing security and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth validation is used for passenger verification, then the validation process is simplified and can be performed automatically, but the system becomes vulnerable to fraud such as ticket sharing, cloning, and device spoofing
Solution Approach 1:
The patent combines Bluetooth Low Energy (BLE) technology with High Frequency Data-over-Voice (HF DOV) audio signals to create a multi-factor authentication system. The validator device simultaneously receives both Bluetooth tokens and audio signals from the passenger's mobile device, requiring both factors to be present and synchronized for successful validation. This merging of two different authentication modalities maintains ease of operation while significantly improving security against fraud.
2Device complexity
If traditional single-factor validation methods are used, then the system is simpler to implement, but it cannot prevent unauthorized access or spoofing effectively
Solution Approach 1:
The validation system is segmented into two distinct authentication factors: Bluetooth token verification and High Frequency Data-over-Voice audio signal verification. Each factor operates independently but must both succeed for validation to complete. This segmentation allows the system to maintain relatively simple individual components while achieving robust security through the combination of multiple independent verification layers, making it difficult for fraudsters to compromise the entire system.

Function Achieved in This Case
The HF DOV-based multi-factor authentication significantly reduces fraudulent behavior, providing a secure and reliable validation process while being cost-effective and compatible with a wide range of devices, thus preventing unauthorized access and ensuring accurate passenger validation.
Implementation Method 1
The validator constantly generates a new Bluetooth (BT) token and sends it to the user's smart mobile device
Implementation Method 2
Based on the prepared BT token, the validator generates a High Frequency Data-over-Voice (HF DOV) audio signal
Implementation Method 3
When the user's smart mobile device receives the HF DOV token, it decodes the synchronisation code and the BT token
