Radio Noise Matching for Physical Presence Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face vulnerabilities in user verification, particularly in remote access scenarios, as current security schemes like username-password, two-factor authentication, and hardware-based methods are susceptible to social engineering and cyberattacks, and lack robust physical presence verification.
Innovation Solution
Utilizing existing radio communication hardware to detect and compare radio noise patterns from multiple sources in the user's and device's environments, synchronizing these patterns to verify co-location and authenticate authorized users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional username-password or two-factor authentication is used, then user verification can be performed, but the system remains vulnerable to social engineering and cyberattacks without physical presence verification
Solution Approach 1:
The patent converts the harmful radio frequency interference and noise into a beneficial authentication mechanism. By detecting and analyzing RF noise patterns from various sources (cell towers, Wi-Fi networks, Bluetooth devices) in the environment, the system creates a unique environmental fingerprint that verifies physical presence. This transforms what was previously considered electromagnetic pollution into a security feature that prevents remote access attacks and social engineering exploits.
2Reliability
If physical presence verification is implemented to prevent remote access threats, then security is enhanced, but additional hardware and complexity are required
Solution Approach 1:
The patent makes the existing radio frequency receiver - already present in every smartphone for cellular communication - perform an additional authentication function. The same hardware that receives cell tower signals now also captures Wi-Fi and Bluetooth noise patterns for security verification. This multi-functionality approach avoids adding dedicated hardware while implementing robust physical presence verification through software-based RF environment analysis.
3Measurement precision
If multiple radio noise sources are monitored to ensure accurate co-location verification, then authentication accuracy is improved, but processing complexity and time increase
Solution Approach 1:
The patent creates a digital copy or fingerprint of the radio frequency environment by recording the patterns, frequencies, and intensities of multiple RF noise sources. This environmental fingerprint is then compared against stored reference fingerprints to verify co-location. By copying and analyzing the characteristics of multiple radio noise sources rather than attempting to identify each individual source, the system achieves high authentication accuracy while managing processing complexity through pattern recognition rather than source enumeration.

AI summary
A method for assuring a person wanting to access an information handling system is an authorized user comprises the information handling system comparing radio noise detected near the information handling system with radio noise detected near a mobile device associated with the authorized user. If the radio noise information matches, the person wanting to use the information handling system may be determined to be the authorized user. If the radio noise does not match, the information handling system may remain locked until the person can be verified as the authorized user.
