UWB Transmitter Position Verification for Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing data integrity through location verification are not precise and can be vulnerable to falsification, especially in enclosed environments, as they rely on connectivity and GPS, which may not provide accurate or reliable location information, allowing for potential identity usurpation and data corruption.
Innovation Solution
A method utilizing UWB radio band messages acquired by multiple beacons to determine the precise location of a transmitter, generating a data pair comprising the decoded information and position information, and verifying the integrity of the data by correlating the position with expected coordinates, making it difficult to falsify the location and ensuring secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If WiFi or Bluetooth connectivity is used to determine position, then the system can verify basic location presence, but the position determination is not precise enough to prevent identity usurpation
Solution Approach 1:
The patent replaces connectivity-based position verification (WiFi/Bluetooth) with UWB (Ultra-Wideband) radio technology. UWB uses time-of-flight measurements of radio signals to determine position with centimeter-level precision, substituting the imprecise connectivity-based system with a physics-based signal propagation measurement system that provides both high precision and high reliability for data integrity control.
2Adaptability or versatility
If GPS satellite location is used, then position data can be obtained, but the precision is insufficient and the system cannot operate in enclosed or partitioned environments
Solution Approach 1:
The patent introduces UWB transceivers and beacons as intermediary devices deployed within enclosed environments to mediate position determination. These intermediaries create a localized positioning infrastructure that works independently of satellite signals, enabling precise position tracking inside buildings, rooms, or partitioned spaces where GPS cannot penetrate.
3Reliability
If position data from GPS or connectivity systems is used as password, then location-based authentication can be implemented, but the system is vulnerable to falsification and identity usurpation
Solution Approach 1:
The patent implements preliminary binding between position information and data integrity verification before the actual transaction occurs. The system pre-establishes expected position coordinates for legitimate data sources and verifies incoming data against these pre-defined position expectations. This preliminary position verification creates a security layer that prevents identity usurpation without requiring complex real-time tracking systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach provides a secure and precise method to verify the origin of data, enhancing the reliability of transactions by correlating the position of the transmitter with expected coordinates, thus preventing identity usurpation and ensuring data integrity, even in enclosed environments.
Implementation Method 1
Acquisition of at least one message in the UWB radio band coming from a transmitter by means of a wireless interface and a UWB demodulator
Implementation Method 2
Determination of a position information, designated second information, of the UWB transmitter from several receptions of messages transmitted by said transmitter
Data Source
AI summary
A method for controlling the integrity of at least one useful datum includes acquiring at least one UWB message coming from a transmitter by a wireless interface; demodulating the at least one UWB message and decoding of at least one useful datum; determining the position of the UWB transmitter by a reception of a plurality of messages transmitted by the transmitter and an analysis of the time-of-flight differences between these messages; associating the calculated position with the at least one useful datum.
