Signals-Based Authentication Using Biometric Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional authentication methods are becoming less secure and more cumbersome, making it difficult to protect user data and prevent unauthorized access.
Innovation Solution
Implementing a signals-based authentication system that uses a user's biometric data, such as heart rate and respiratory rate, to automatically authenticate users by detecting their devices within a predefined proximity of an authentication device, without requiring additional user input, if the confidence level meets a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then user data protection and unauthorized access prevention are compromised, but the authentication process becomes less secure
Solution Approach 1:
The system performs automatic authentication by detecting user presence through device signals and comparing biometric data without requiring active user participation. The authentication process serves itself by automatically initiating detection, analyzing biometric data, and making authentication decisions without user intervention, thereby maintaining high security while improving convenience.
Solution Approach 2:
The patent replaces traditional mechanical authentication methods (keyboards, fingerprint scanners requiring active input) with signal-based detection systems that passively monitor device emissions and biometric data. This substitution enables automatic authentication through environmental sensing rather than direct user interaction, resolving the contradiction between security and convenience.
2Ease of operation
If automatic authentication based on biometric data is implemented, then authentication convenience is improved, but the complexity of the authentication device increases
Solution Approach 1:
The authentication device integrates multiple functions into a single system: it detects user presence through device signals, captures biometric data, processes authentication logic, and communicates results. This multi-functional integration achieves automatic authentication convenience while managing complexity through consolidated design rather than separate components.
Solution Approach 2:
The system uses the user's own device as an intermediary to facilitate authentication. The device signals and biometric data serve as mediators between the user and the authentication system, enabling automatic verification without requiring the authentication device to directly interact with the user, thereby simplifying the overall system architecture.
3Reliability
If traditional authentication methods are used, then device complexity is reduced, but authentication security and reliability deteriorate
Solution Approach 1:
The system performs preliminary detection of user presence and biometric data collection before the actual authentication decision is made. By pre-gathering necessary information through device signal detection and biometric monitoring, the system establishes a foundation for secure authentication while managing complexity through staged processing rather than simultaneous operations.

AI summary
Arrangements for automatically authenticating a user based on a signals-based footprint of the user are provided. In some examples, an authentication device may continuously scan a predefined area surrounding the authentication device. Upon detecting a user device, a determination may be made as to whether the device is detected for at least a threshold amount of time. If so, user data may be requested. In some examples, the user data may be requested from, for example, a mobile device of a user and may include biometric signature data, such as heart rate, respiratory rate, and the like. User response data may be received and compared to pre-stored data and, if the user response data meets or exceeds a threshold confidence level, the user may be automatically authenticated. If not, additional user authentication information, such as a username and password, personal identification number (PIN), or the like, may be requested to authenticate the user.
