Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR environments face challenges in secure authentication due to the difficulty in using traditional input devices like keyboards and mice, and simple gesture passwords are easily copied, necessitating a more secure and user-friendly method for gesture-based authentication.
Innovation Solution
A method that captures and analyzes user gestures for complexity, suggesting amendments to increase or decrease complexity as needed, using machine learning to ensure the gesture is both secure and repeatable, with visual and auditory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional input devices like keyboards and mice are used in XR environments, then authentication can be performed, but the user experience deteriorates due to occlusion and difficulty in finding/using the devices
Solution Approach 1:
The patent replaces mechanical input devices (keyboards and mice) with gesture-based authentication using motion tracking technology. The system captures hand movements and gestures through cameras or sensors, translating physical gestures into digital authentication signals without requiring traditional mechanical interfaces.
Solution Approach 2:
The patent creates a virtual representation of the user's physical gestures by capturing motion data and processing it into authentication tokens. The system copies the essential characteristics of hand movements and transforms them into a secure authentication mechanism that functions within the XR environment.
2Ease of operation
If simple gesture passwords are used for authentication, then ease of operation improves, but security deteriorates because gestures are easily copied by observation
Solution Approach 1:
The patent enhances gesture security by adding temporal and dynamic dimensions to the authentication process. Instead of static gesture patterns, the system analyzes gesture velocity, acceleration, pressure, and timing characteristics, creating a multi-dimensional authentication space that is much harder to replicate through simple observation.
Solution Approach 2:
The patent transforms the gesture authentication system by changing multiple parameters simultaneously - incorporating velocity, acceleration, pressure, timing, and sequence variations. These parameter changes create a complex authentication signature that maintains ease of use while dramatically improving security against copying.
3Reliability
If complex gestures are required to improve security, then authentication security improves, but ease of operation deteriorates due to difficulty in remembering and executing gestures
Solution Approach 1:
The patent divides the authentication gesture into multiple segments or phases, where each segment contributes to the overall security through its unique characteristics. The system can validate each segment independently, allowing for modular complexity that enhances security without requiring the user to remember an entirely complex sequence.
Solution Approach 2:
The patent introduces dynamic adaptability to gesture complexity, where the system can adjust the required gesture complexity based on security requirements and user capability. The authentication system dynamically modifies gesture parameters such as speed, pressure, and sequence length to balance security needs with user ease of operation.

AI summary
A method, computer system and computer program are provided for achieving a secure authentication token for accessing an application. The method captures a user gesture provided by a user as an authentication token and analyses the gesture to evaluate a measure of complexity of the gesture. Responsive to a determination that the measure of complexity does not meet a minimum measure of complexity, an amendment is determined and proposed to the gesture to increase a complexity of the gesture. The capturing and analysing steps are repeated, and, responsive to a determination that the gesture meets the minimum measure of complexity, the gesture is approved as a secure authentication token.
