Solution Overview

Problem

Current user authentication methods compromise privacy, are prone to hacking, require real-time network access, and are not intuitive or adaptable to different devices and environments, limiting their usability and reliability.

Innovation Solution

A system that uses smart devices to interact with peripheral devices via gesture recognition, where a user device captures biometric and motion data, authenticates with a server, and sends a token to a reader device to authorize actions on peripheral devices, allowing offline access and maintaining user privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If biometric data is captured and transmitted over computer networks for authentication, then user identification accuracy is improved, but user privacy is compromised and security vulnerabilities increase

Engineering Contradiction:

Improveuser identification accuracyVSAvoidprivacy compromise and security vulnerabilities

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes personally identifiable information from the authentication process. Instead of transmitting actual biometric data or personal identifiers over networks, the system uses anonymous device identifiers and local gesture recognition, eliminating sensitive data from network transmission while maintaining authentication functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system creates and uses anonymous copies or representations instead of original sensitive data. Device identifiers serve as anonymous copies that enable authentication without exposing actual user identity or biometric information, and gesture patterns are recognized locally without transmitting the actual motion data.

Inventive Principle:

Principle #26Copying

2Extent of automation

If real-time network access is required for authentication, then centralized control and logging are improved, but system reliability and usability in offline environments deteriorate

Engineering Contradiction:

Improvecentralized control and loggingVSAvoidsystem reliability in offline environments

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The system performs preliminary authentication and establishes device identifiers before offline operations are needed. Device identifiers are pre-configured and stored locally, enabling authentication to proceed without real-time network access. Logging and control functions are designed to operate with delayed synchronization rather than requiring continuous connectivity.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If traditional authentication methods are used, then security protocols are maintained, but user convenience and accessibility deteriorate

Engineering Contradiction:

Improvesecurity protocol complianceVSAvoiduser convenience and accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical authentication methods (keycards, biometric scanners, password entry) with gesture-based recognition using device sensors. This substitution maintains security through authenticated device identifiers while dramatically improving ease of operation, particularly for users with physical limitations who can perform gestures more easily than traditional authentication methods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If dedicated hardware such as badges is used for authentication, then access control reliability is improved, but cost and device portability deteriorate

Engineering Contradiction:

Improveaccess control reliabilityVSAvoidcost and portability

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system makes the user's existing smartphone or wearable device universal for multiple functions: it serves as both the authentication credential (replacing badges) and the gesture recognition platform. This eliminates the need for separate dedicated authentication hardware while maintaining access control reliability through device-specific identifiers and secure gesture patterns.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for a system includes capturing with a biometric capture device biometric data associated with a user of a smart device, determining with processor a user profile in response to the biometric data, determining with a physical sensor a plurality of physical perturbations in response to physical actions of the user, determining with the processor a requested user-perceptible action in response to the user profile and the plurality of physical perturbations, receiving with a short-range transceiver an authentication request from a reader device, and outputting with the short-range transceiver a token and identification of the user-perceptible action to the reader device in response to the authentication request, wherein the reader device performs or directs performance of the user-perceptible action in response to the identification of the user-perceptible action and to the token being valid.
