Game Board Authentication Method for Secure Mobile Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Alphanumeric passcodes lack mathematical robustness and are difficult for users to remember, leading to security vulnerabilities and interference between similar memory-based codes, making it challenging to achieve both high security and memorability.
Innovation Solution
An interactive game board authentication method using graphical game boards and pieces, where users select and move game pieces on a board to generate a passcode, combining game selection, piece identity, and spatial relationships, with the option for game-changing attributes to avoid memory interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If alphanumeric passcodes are used for authentication, then ease of operation is improved, but mathematical robustness deteriorates
Solution Approach 1:
The passcode is segmented into multiple components: game selection, game piece selection, and spatial positioning on the board. This segmentation dramatically increases the total number of permutations while maintaining ease of use through familiar game interfaces.
Solution Approach 2:
The authentication system transitions from one-dimensional alphanumeric strings to multi-dimensional game board configurations, incorporating spatial relationships, piece identities, and board states to create a vastly expanded permutation space.
2Ease of operation
If simple alphanumeric passcodes are used, then ease of operation is improved, but memorability deteriorates
Solution Approach 1:
Familiar games serve as an intermediary layer between the user and the authentication code. Users interact with games they already know and enjoy, which provides natural mnemonic anchors without requiring them to remember abstract alphanumeric sequences.
Solution Approach 2:
The system utilizes visual differentiation through game pieces and board configurations, creating distinct visual patterns that are easy to remember and distinguish from one another, avoiding the confusion of similar alphanumeric strings.
3Adaptability or versatility
If multiple alphanumeric passcodes are used for different devices, then adaptability is improved, but memorability deteriorates
Solution Approach 1:
The game-based authentication system provides a universal interface that works across different devices and contexts. Users can play chess, checkers, or other familiar games on any computing device, making the authentication process consistent and memorable regardless of the specific device.
Solution Approach 2:
The system allows dynamic selection of different games and board configurations based on the device or context, providing adaptability while maintaining consistency through the use of familiar game mechanics that users can remember across different scenarios.

AI summary
An authentication method and system includes a computing device, such as a smart phone, which includes a display for presenting a graphical and interactive game board that is used for entering a user's passcode. During the authentication process, the user selects a game board (e.g. chess, checkers, poker, backgammon, etc.) and associated game pieces for presentation on the display. The user then moves one or more game pieces to locations on the game board. Together, the selected game board, selected game pieces, and the movements and/or locations which the game pieces are moved on the game board form an entered passcode. This generated passcode is then compared with a stored passcode to authenticate the user before granting access to the computing device.
