TPMS Sensor ID Rotation for Anti-Tracking Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Tire Pressure Monitoring Systems (TPMS) can be used to track vehicle locations unintentionally and are vulnerable to data spoofing due to the use of low-power wireless technologies like Bluetooth Low Energy (BLE), making it possible for outside sources to monitor and alter tire pressure data.
Innovation Solution
The system generates a new unique identification for each TPMS sensor automatically in response to specific conditions, such as vehicle movement or ignition, using sensor parameters like time, battery state, and position, and deploys encryption to obscure and secure the data transmission, preventing unauthorized tracking and data alteration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If low-power wireless technologies like BLE are used for TPMS data transmission, then energy consumption is reduced and transmission efficiency is improved, but vehicle location tracking becomes possible and data security is compromised
Solution Approach 1:
The patent implements dynamic identification by randomly changing the TPMS sensor identification at predetermined intervals. This dynamic approach maintains the low-power BLE transmission while preventing tracking, as the identification used for communication changes over time rather than remaining static.
Solution Approach 2:
The system changes the identification parameter of the TPMS sensor at predetermined intervals. By modifying this key parameter, the system maintains communication efficiency while eliminating the ability of external systems to track the vehicle through consistent identification.
2Ease of operation
If static unique identification is used for TPMS sensors, then data transmission is simplified and communication is efficient, but vehicle tracking becomes possible and data integrity is vulnerable to spoofing
Solution Approach 1:
The patent transforms the static identification into a dynamic parameter that changes at predetermined intervals. This maintains communication simplicity while significantly improving reliability by preventing spoofing attacks that would require capturing and replaying static identification data.
Solution Approach 2:
The system implements periodic changes to the sensor identification at predetermined intervals. This periodic action maintains efficient communication during each interval while periodically refreshing the identification to prevent tracking and spoofing over longer periods.
3Object-affected harmful factors
If TPMS sensor identification changes frequently, then location tracking is prevented and data security is improved, but system complexity increases and communication protocols become more complex
Solution Approach 1:
The patent implements identification changes at predetermined intervals rather than continuously. This periodic approach provides security benefits while limiting system complexity, as the communication protocol only needs to handle identification changes at specific intervals rather than requiring continuous complex authentication.

AI summary
An apparatus and method include, among other things, providing a plurality of sensors for a tire pressure monitoring system where each sensor is associated with tire parameter properties and has sensor parameters. Each sensor has a unique initial identification. A new unique identification is automatically generated for each sensor to replace the initial identification in response to a predetermined condition that is associated with at least one sensor parameter.
