Wearable Authentication Using Dynamic Hand Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable user devices face security deficiencies in authentication methods, as voice recognition and touchpad input are susceptible to interception and errors, and lack robustness against unauthorized access.
Innovation Solution
A wearable user device system that displays authentication elements in varying orientations, allowing users to select and input sequences using hand movements, which changes with each authentication attempt, making it difficult for unauthorized users to replicate the gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used for authentication, then ease of operation is improved, but security is worsened due to interception risks
Solution Approach 1:
The patent replaces voice recognition (acoustic field) with hand gesture recognition (visual field). The system captures hand gestures via camera and processes them to authenticate users, eliminating the interception vulnerability of voice while maintaining ease of operation through intuitive physical gestures.
Solution Approach 2:
The patent introduces a camera as an intermediary device to capture hand gestures, which then serve as the authentication input. This intermediary visual-based system replaces the direct acoustic field interaction of voice recognition, creating a secure authentication channel that is not susceptible to interception.
2Ease of operation
If touchpad input is used for authentication, then ease of operation is improved, but reliability is worsened due to time consumption and errors
Solution Approach 1:
The patent replaces the mechanical touchpad interface with optical hand gesture recognition. Instead of physical contact input that requires deliberate pressing and is prone to errors, the system uses camera-based gesture capture that is faster, more intuitive, and more accurate for authentication purposes.
3Ease of operation
If fixed authentication patterns are used, then ease of operation is improved, but security is worsened due to predictability
Solution Approach 1:
The patent implements dynamic authentication by randomly selecting from multiple authentication patterns each time. The system maintains a set of valid gesture patterns and randomly chooses which one to present for authentication, ensuring that the authentication sequence changes with each attempt and cannot be predicted or replicated by observers.
Solution Approach 2:
The patent employs periodic randomization of authentication patterns. Each authentication attempt uses a different pattern selected from a predefined set, creating a periodic variation in the authentication sequence that prevents predictability while maintaining ease of operation through consistent gesture-based interaction.

AI summary
Systems and methods for authenticating a user include a wearable user device receiving a first request to access a secure system. A plurality of authentication elements are then displayed on a display device to a user eye in a first authentication orientation about a perimeter of an authentication element input area. A user hand located opposite the display device from the user eye is then detected selecting a sequence of the plurality of authentication elements. For each selected authentication element in the sequence, the wearable user device moves the selected authentication element based on a detected movement of the user hand and records the selected authentication element as a portion of an authentication input in response to the user hand moving the selected authentication element to the authentication element input area. The user is authenticated for the secure system if the authentication input matches stored user authentication information.
