Continuous Biometric Control for Real-Time User State Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively mitigate risks posed by human error, misjudgment, and wrongdoing in interactions with computing systems without causing unnecessary detriment to system function, particularly in scenarios where human-machine interactions can have widespread adverse effects.
Innovation Solution
A computer-implemented method for continuous control using passive biometric readings to authenticate user identity and infer their state of mind, applying policies to determine appropriate actions based on multiple biometric inferences weighted by confidence scores, allowing for real-time adaptation to user mood or mental state without requiring user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional authentication checks are required at key decision points to mitigate risks from human error and malicious behavior, then security is improved, but system operation speed deteriorates
Solution Approach 1:
The system performs continuous passive biometric monitoring and authentication in the background before critical decisions occur. By continuously assessing the user's state of mind and physiological condition throughout the interaction, the system prepares authentication verification in advance, so that when a key decision point is reached, the security check can be performed rapidly without interrupting the user flow or requiring additional active user actions.
2Measurement precision
If biometric monitoring is performed continuously to prevent spoofing, then detection accuracy is improved, but complexity of the system increases
Solution Approach 1:
The system employs a multi-functional biometric monitoring apparatus that simultaneously performs multiple tasks: continuous authentication verification, state of mind assessment, physiological condition monitoring, and spoofing detection. By consolidating these functions into a single integrated system rather than separate components, the patent reduces overall system complexity while maintaining high detection accuracy through the coordinated operation of multiple biometric parameters.
3Reliability
If multiple biometric parameters are monitored to assess user state, then reliability of state assessment is improved, but quantity of data processing increases
Solution Approach 1:
The system extracts and processes only the essential biometric parameters and features that are most indicative of the user's state of mind and authentication validity. Rather than processing all available biometric data equally, the patent identifies and focuses on key discriminative features from multiple biometric sources, filtering out redundant information. This selective extraction approach maintains high assessment reliability while significantly reducing the volume of data that requires processing.

AI summary
The present disclosure relates to improving ways of making decisions made by, or with the assistance of, computing systems. One aspect relates to a computer-implemented continuous control method, the method comprising: obtaining a policy decision according to an application of a policy to an inference; the inference being of an authorised user's state of mind over a time interval, determined according to a plurality of biometric readings obtained passively from the user over the time interval for continuous authentication of the user; the user's identity having been continuously authenticated according to the plurality of biometric readings; and causing one or more actions in accordance with the policy decision. Further aspects relate to a data processing system comprising means for carrying out such a method, a computer program comprising instructions which, when the program is executed by a computer, cause the computer to carry out such a method, a computer-readable data carrier having stored thereon such a computer program and a data carrier signal carrying such a computer program.
