Wireless Device Characterization via Telemetric Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As more electronic devices communicate over wireless networks, accurately characterizing individual devices becomes challenging due to the limitations of Media Access Control (MAC) addresses, which do not provide sufficient information about the device's type, usage, or user demographics.
Innovation Solution
A system and method that utilize machine learning to analyze telemetric properties such as connection times, data transfer rates, and signal strength to determine probabilities and patterns associated with user devices, allowing for characterization without accessing individual data packets, thus addressing privacy concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data content analysis is used to identify device properties, then measurement precision is improved, but privacy protection deteriorates
Solution Approach 1:
The patent extracts only the necessary telemetric properties (connection times, data transfer rates, signal strength) from the data stream while leaving the actual data content untouched. This extraction approach enables device characterization without requiring access to or analysis of private data contents, thus resolving the contradiction between measurement precision and privacy protection.
Solution Approach 2:
The patent introduces telemetric properties as an intermediary between raw data and device characterization. Instead of directly analyzing data content to identify device properties, the system uses telemetric properties (connection times, data transfer rates, signal strength) as a mediator that provides sufficient information for characterization while preserving data privacy.
2Ease of operation
If MAC address is used for device identification, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent merges MAC address identification with telemetric property analysis. Instead of relying solely on MAC addresses for device identification, the system combines this simple identifier with additional telemetric data (connection times, data transfer rates, signal strength) to achieve both ease of operation and improved measurement precision for device characterization.
Solution Approach 2:
The patent performs preliminary characterization using MAC addresses, then refines the characterization by incorporating telemetric properties. This preliminary action approach allows the system to quickly identify devices using simple MAC addresses while subsequently improving characterization accuracy through additional telemetric analysis.
