Engineering Contradiction Analysis
1Measurement precision
If GNSS signals are used for authentication services, then positioning and timing information can be obtained, but the signals are vulnerable to manipulation leading to data integrity issues
Solution Approach 1:
The patent introduces an intermediary verification system that mediates between the GNSS signal source and the authentication service. The verification device checks the integrity of positioning information by comparing it against expected values or cryptographic signatures, acting as a trusted intermediary that prevents direct manipulation of authentication data while maintaining the benefits of GNSS-based positioning.
2Reliability
If verification of positioning information is added, then data reliability is improved, but system complexity increases
Solution Approach 1:
The verification of positioning information is performed preliminarily, before the authentication service is finalized. By verifying the integrity of GNSS data in advance and only then proceeding with authentication, the system ensures reliability without requiring complex real-time verification mechanisms during the critical authentication moment.
Data Source
AI summary
A verified authentication device has a navigation receiver, a processor, and a verification device. Navigation signals are transmitted from a Global Navigation Satellite System (GNSS). The processor authenticates the navigation signals and determines position coordinates of the navigation receiver. The verified authentication device receives input from a user of the verified authentication device. The verified authentication device provides reliability of the position coordinates based on the input from the user.
