Multi-pattern Authentication Gesture Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods, particularly those relying on something the user knows (Factor 2), are insecure due to ease of sharing, guessing, or observation, and require frequent password changes, which complicates secure access management.
Innovation Solution
Implementing a multi-pattern authentication gesture that combines temporal and positional dimensions, allowing users to create complex gestures that can be securely shared and adapted over time, using multi-pattern input devices like multi-touch sensors or video cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional Factor 2 authentication methods (passwords, PINs) are used, then ease of operation is improved, but security is worsened due to ease of sharing, guessing, or observation
Solution Approach 1:
The patent transforms traditional 1D password input into 2D/3D spatial gestures with temporal dimensions. Users perform gestures in space (x, y, z coordinates) over time, creating multi-dimensional authentication patterns that are much harder to observe, guess, or share than traditional passwords while remaining operable through natural hand movements.
Solution Approach 2:
The authentication system uses dynamic, time-varying gestures instead of static passwords. The gestures have temporal components (duration, speed, sequence) and spatial components (trajectory, position, shape), creating a dynamic authentication mechanism that adapts to user movement patterns and is difficult to replicate without precise temporal and spatial knowledge.
2Reliability
If frequent password changes are required to maintain security, then security is improved, but device complexity and user burden increase
Solution Approach 1:
The system allows users to naturally create and change their own gesture patterns without administrator intervention or complex procedures. Users can modify their gestures organically over time, and the system automatically adapts to the new patterns, eliminating the need for formal password change protocols and reducing authentication management complexity.
Solution Approach 2:
Instead of forcing periodic password changes, the system naturally accommodates periodic gesture evolution. Users can and do change their gestures over time, and the system continuously adapts to recognize the new patterns, transforming the rigid periodic change requirement into a flexible continuous adaptation process.
3Reliability
If complex authentication credentials are used to improve security, then security is improved, but ease of operation is worsened
Solution Approach 1:
The patent replaces the mechanical act of typing passwords with natural hand gestures in three-dimensional space. This substitution leverages the human body's natural movement capabilities, making complex authentication feel as intuitive as making hand gestures in conversation, thereby maintaining ease of operation while dramatically increasing security through spatial and temporal complexity.

AI summary
Apparatus, methods, and computer program products are disclosed for using gestures to authenticate a principal. The method acquires a multi-pattern authentication gesture that has multiple input patterns. The multiple input patterns have a temporal dimension. At least two of the multiple input patterns overlap in the temporal dimension. The multi-pattern authentication gesture also has a duration. The method compares whether the multi-pattern authentication gesture is sufficiently similar to an available gesture template over a portion of the duration and assigns a level-of-trust to the principal responsive to the comparison. The apparatus and program products use the method.
