Quantum Credential Verification for Eavesdropping and Fraud Origin Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting payment fraud and unauthorized network access are inadequate in preventing eavesdropping and identifying the origin of fraudulent activities, as they do not effectively secure the verification process against interception.
Innovation Solution
Utilizing a quantum channel for password exchange through Quantum Key Distribution (QKD) to detect eavesdropping and perform out-of-band verification, flagging potential fraudulent transactions by storing false verification information and monitoring device information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional verification methods are used to secure credentials, then verification can be performed, but the system is vulnerable to eavesdropping and cannot identify the origin of fraud
Solution Approach 1:
The patent introduces a quantum channel as an intermediary communication path between the user device and server. This quantum channel enables secure credential transmission through quantum key distribution, detecting eavesdropping attempts while maintaining the ability to identify fraudulent device origins through classical channel correlation
Solution Approach 2:
The verification system is segmented into two independent channels: a quantum channel for secure credential exchange and a classical channel for device information transmission. This segmentation allows the quantum channel to provide eavesdropping detection while the classical channel tracks device origins, resolving the contradiction between security and fraud identification capability
2Reliability
If quantum key distribution is used for password exchange, then eavesdropping can be detected, but the system complexity increases
Solution Approach 1:
The patent applies partial quantum action by using quantum key distribution only for the critical credential transmission phase, while relying on classical channels for device information exchange and fraud detection. This partial application of quantum technology provides eavesdropping detection without requiring full quantum system complexity throughout the entire verification process
3Measurement precision
If verification information is stored for fraud detection, then potential fraud origins can be identified, but false verification information may be stored incorrectly
Solution Approach 1:
The patent implements feedback mechanisms where the server compares verification information against stored data and provides responses that guide further verification steps. When verification fails or suspicious patterns are detected, the system feeds back device information for additional analysis, improving both fraud origin identification and verification accuracy through iterative validation

AI summary
The arrangements disclosed herein relate to systems, apparatus, methods, and non-transitory computer readable media for receiving, by a server from a first device via a quantum channel, first verification information associated with a user of the first device. The server determines that the first verification information fails to verify against second verification information. In response to determining that the first verification information fails to verify against second verification information, the server stores the first verification information. In response to receiving, by the server from a second device, the first verification information and device information of the second device, the server flags the device information of the second device as a potential origin of fraud.
