Game-like Multi-level Authentication for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device security systems are cumbersome for shared environments, particularly for young users, as they require complex password management and login/logout processes, which are difficult to implement and maintain, especially when devices are frequently shared among family or school users.
Innovation Solution
A game-like multi-level authentication system using drawing and gesture recognition, where users create a profile by responding to challenges, such as drawing numbers or identifying shapes, and are authenticated by comparing their responses to stored records, providing a more intuitive and accessible method for identity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password authentication is used, then security is improved, but ease of operation deteriorates for young users
Solution Approach 1:
The patent replaces the mechanical typing system (keyboard input for passwords) with a graphical interaction system (touchscreen drawing and gesture recognition). This substitution allows young users to authenticate through natural drawing and gesturing actions rather than memorizing and typing complex passwords, thereby maintaining security while dramatically improving ease of operation for children and non-literate users.
Solution Approach 2:
The patent changes the authentication parameter from discrete symbolic input (password characters) to continuous spatial-temporal patterns (drawings and gestures). By transforming the authentication mechanism from text-based to visual-motor-based, the system maintains security through pattern recognition while making the process intuitive for young users who can draw and gesture naturally without needing to read or type.
2Reliability
If data segregation is implemented for multiple users, then security is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service authentication where the system automatically captures, stores, and compares drawing/gesture patterns without requiring manual setup or configuration. The device autonomously manages user profiles and authentication verification, reducing the operational complexity of implementing multi-user data segregation while maintaining strong security through biometric-like pattern recognition.
3Reliability
If password authentication is required, then security is improved, but productivity deteriorates due to frequent login/logout
Solution Approach 1:
The patent performs preliminary action by capturing and storing the user's drawing and gesture patterns during an initial setup phase. This pre-captured biometric-like data enables rapid authentication during subsequent logins, eliminating the need for users to repeatedly type passwords. The system quickly compares new drawings/gestures against stored patterns, significantly reducing authentication time and improving productivity while maintaining security.

AI summary
The disclosed embodiments provide a convenient way for users to access segregated work spaces on mobile devices. A game-like multi-level interactive approach is used to prompt users for input to verify their identity. Multiple identity verification attributes can be collected at each level of interaction. Authentication is achieved when a settable level of user identification confidence is reached. This can potentially reduce the amount of interaction needed as compared to requiring a user to type in a long, cryptic password.
