Word-Gesture Pair Authentication for Device-Independent User Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods, such as password and biometric systems, face challenges in providing a user-friendly, robust, and device-independent way to create and authenticate gesture-based passwords, often requiring specific hardware or being difficult to replicate across different devices.
Innovation Solution
A data processing system that uses a combination of word and gesture pair indications, where users input a sequence of words and gestures, which are then compared to stored authentication data, allowing for flexible and device-independent authentication through a computer processor and storage device, capable of processing sound and image inputs from user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is used, then user authentication reliability is improved, but device complexity increases due to requirement of special hardware such as fingerprint scanners
Solution Approach 1:
The patent replaces mechanical biometric systems (fingerprint scanners, hardware sensors) with a software-based gesture recognition system that uses standard camera inputs. The gesture-based authentication mechanism substitutes complex hardware requirements with simpler, more universally available camera-based input collection, thereby reducing device complexity while maintaining authentication reliability through the combination of word and gesture pair recognition
2Ease of operation
If gesture-based authentication is used, then ease of operation is improved, but device complexity increases due to requirement of complex processing and object tracking
Solution Approach 1:
The patent segments the authentication process into distinct components: word recognition and gesture recognition as separate but combined elements. By breaking down the authentication into word-gesture pairs rather than requiring complex continuous gesture sequences, the system reduces processing complexity while maintaining ease of operation. Each pair can be independently processed and verified
Solution Approach 2:
The patent introduces an intermediary authentication server that handles the complex gesture recognition and verification processes remotely. This intermediary service offloads complex object tracking and gesture analysis from the user's device, reducing local device complexity while maintaining ease of operation through simplified client-side interaction
3Measurement precision
If device-specific authentication is used, then measurement precision is improved, but adaptability deteriorates as signature may not match across different devices
Solution Approach 1:
The patent creates a universal authentication system where word-gesture pairs can be recognized and verified across multiple different devices. The authentication mechanism is designed to be device-independent, allowing the same authentication to work on different cameras and processing systems. This universality is achieved through standardized gesture recognition and cloud-based verification that doesn't depend on device-specific sensors or characteristics
