Dynamic Graphical Password Sequence Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face password fatigue due to the need to remember multiple accounts and passwords, leading to weak or reused passwords, and security systems that require frequent password changes can be cumbersome and insecure due to password stagnation.
Innovation Solution
A dynamic graphical password system that adapts over time based on user preferences and patterns, using a selection grid with customizable elements, categories, and authentication scores to create a secure and user-friendly authentication method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passwords are required to be changed frequently to maintain security, then security is improved, but user convenience deteriorates due to password fatigue and complexity
Solution Approach 1:
The patent implements dynamic password adaptation where the password sequence automatically evolves over time based on user interaction patterns. The system monitors user preferences and behavior, then dynamically modifies password requirements without forcing complete changes. This resolves the contradiction by making password security adaptive rather than static, maintaining strong security while adapting to user habits to reduce fatigue.
Solution Approach 2:
The system automatically monitors user patterns and adapts password sequences without requiring user intervention for password changes. The authentication system self-adjusts based on observed user behavior, eliminating the burden of manual password updates while maintaining security through automated adaptation to user preferences.
2Reliability
If complex passwords are used to enhance security, then security is improved, but password retention by users deteriorates
Solution Approach 1:
The patent creates a dynamic password system that adapts its complexity based on user patterns rather than imposing static complex requirements. The system evolves password sequences over time based on user preferences, making the complexity adaptive rather than fixed. This allows security to be maintained through dynamic adaptation while reducing the burden of remembering permanently complex passwords.
Solution Approach 2:
The system incorporates feedback loops that monitor user interaction with password sequences and automatically adjust complexity based on observed patterns. By continuously learning from user behavior and adapting password requirements, the system maintains security through intelligent adaptation rather than relying on users to remember increasingly complex static passwords.
3Ease of operation
If password sequences are made static and fixed, then ease of operation is improved, but security deteriorates due to password stagnation
Solution Approach 1:
The patent implements a fundamentally dynamic password system where sequences automatically evolve over time based on user patterns. Rather than being static, the password requirements adapt continuously, preventing stagnation while maintaining ease of operation through automated adaptation to user preferences rather than forcing frequent manual changes.
4Reliability
If multiple password restrictions are imposed to increase security, then security is improved, but password retention by users deteriorates
Solution Approach 1:
The patent replaces static password restrictions with dynamic adaptation. Instead of imposing fixed rules that users must remember, the system automatically adjusts password sequences based on user patterns. This eliminates the need for users to retain multiple restrictive rules while maintaining security through intelligent, automated adaptation to individual user preferences and behaviors.

AI summary
A method of dynamically adapting a secure graphical password sequence provides a secure means to access a restricted account through a dynamic password defined by element selection requirements. A selection grid is dynamically generated with graphical elements, and a password sequence is inputted by selecting certain grid cells containing graphical elements. Various preferences provide full customizability for the dynamic password, and security measures increase the difficulty of an undesirable user ascertaining the element selection requirements. The dynamic password can adapt over time through user input by designating one of the sequential locations of the password sequence as a sequence updating parameter.
