Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture-based authentication is used in XR environments, then ease of operation is improved, but security is worsened due to easy copying of simple gestures
Solution Approach 1:
The patent applies parameter changes by transforming the gesture authentication from simple spatial movements to complex multi-dimensional parameter combinations including spatial coordinates, temporal sequencing, velocity profiles, acceleration patterns, and pressure forces. This transformation maintains ease of operation while significantly enhancing security through increased gesture complexity that is difficult to copy or replicate.
Solution Approach 2:
The patent employs composite materials principle by creating a composite authentication gesture that integrates multiple physical parameters (spatial position, time, velocity, acceleration, force) into a single authentication token. This composite gesture structure provides both user-friendly operation and high security, as the combination of multiple parameters makes the gesture difficult to replicate while remaining executable by users.
2Reliability
If complex gestures are required for security, then security is improved, but ease of operation deteriorates due to difficulty in remembering and repeating gestures
Solution Approach 1:
The patent applies partial or excessive action by implementing a two-stage authentication process where the system first captures and analyzes the gesture to evaluate complexity, then requests repetition only if the initial gesture meets security thresholds. This partial approach allows the system to accept simpler gestures when sufficient while requiring complex repeated gestures only when necessary for security, balancing usability and security requirements.
Solution Approach 2:
The patent implements feedback mechanisms by analyzing the captured gesture's complexity metrics and providing real-time evaluation to the user. The system feedbacks whether the gesture meets the defined complexity threshold and guides users to adjust their gestures accordingly, making the authentication process adaptive and user-friendly while maintaining security standards.
3Reliability
If gesture complexity is increased to prevent copying, then security is improved, but repeatability deteriorates making authentication harder to complete
Solution Approach 1:
The patent applies dynamics by making the authentication process adaptive and flexible. The system dynamically adjusts the authentication requirements based on the analyzed complexity of the user's gesture. If the gesture is sufficiently complex, the system accepts it with fewer repetition requirements; if less complex, it requests additional repetitions. This dynamic approach optimizes both security and authentication speed based on real-time gesture analysis.
Solution Approach 2:
The patent implements preliminary action by performing a preliminary analysis of the gesture's complexity metrics before finalizing the authentication requirements. This preliminary evaluation allows the system to pre-determine the appropriate repetition threshold, avoiding unnecessary repetitions for complex gestures and ensuring sufficient verification for simpler ones, thereby optimizing authentication efficiency while maintaining security.
Data Source
AI summary
A method, computer system and non-transitory computer-readable storage medium are provided for validating a secure authentication token for accessing an application. The method captures a user gesture provided by a user as an authentication token and analyzes 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, repeating the capturing and analyzing steps until the gesture meets the defined measure of complexity. Then the user is requested to repeat the approved gesture and the repeated gesture is captured, and it is determined if the repeated gesture meets defined requirements for repeatability. Responsive to a determination that the repeated gesture does not meet the requirements for repeatability, the method is repeated; and, responsive to a determination that the repeated gesture does meet the requirements for repeatability, the gesture is validated as a secure authentication token.
