Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network registration methods, such as those using conventional passwords and graphical passwords, face issues with security and usability, including vulnerability to cracking and difficulty in remembering complex passwords, as well as limitations in scenarios where hardware tokens are not available.
Innovation Solution
A dynamic graphical password-based network registration method and system that generates two dynamic graphical passwords using full-element dynamic factor tables, where positioning factor strings are mapped to create unique and complex passwords, allowing users to input passwords based on positioning rules, enhancing security and ease of use without relying on hardware devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional passwords are used for network registration, then the registration process is simple and easy to implement, but the security is weak and passwords are easy to be stolen and cracked
Solution Approach 1:
The patent applies dynamics by transforming static passwords into dynamic graphical passwords. The system generates random graphical passwords that change over time and across different sessions, making the authentication mechanism dynamic rather than static. This resolves the contradiction by providing strong security through randomness and temporal variation while maintaining ease of use through graphical interaction.
Solution Approach 2:
The patent replaces the mechanical keyboard input system with a graphical touch-based system. Instead of typing passwords on a keyboard, users interact with graphical elements on a touchscreen display. This substitution eliminates the need to remember complex character sequences while maintaining security through graphical pattern recognition and touch interaction analysis.
2Reliability
If graphical passwords are used for network registration, then security is improved and passwords are easy to remember, but the method is only applicable to stand-alone situations and cannot meet the security needs of great Internet users during registration
Solution Approach 1:
The patent achieves universality by designing a graphical password system that can be deployed across multiple platforms and scenarios. The system supports both stand-alone applications and large-scale Internet services, accommodating different user volumes and security requirements. The core authentication mechanism remains consistent while adapting to various deployment contexts, from individual devices to server farms.
Solution Approach 2:
The patent applies segmentation by dividing the graphical password system into modular components that can be independently deployed and scaled. The system separates the password generation, verification, and management functions into distinct modules that can be distributed across multiple servers and devices. This enables the system to handle both small-scale and large-scale Internet services effectively.
3Ease of operation
If fixed graphic passwords are used, then the password is easy to input through touch screen operations, but tap or slide traces are easily left on the screen and the user password is easily guessed according to the trace
Solution Approach 1:
The patent applies periodic action by implementing time-varying graphical passwords that change at regular intervals or between authentication sessions. The graphical elements, their positions, and configurations are periodically updated, ensuring that even if traces are left on the screen, they become meaningless after a short period. This temporal variation eliminates the security risk of trace analysis while maintaining input convenience.
4Device complexity
If the number of points of the graphic is limited and each point can only be used once, then the graphical password structure is simple, but only a small number of available graphical passwords can be generated and the passwords have a high repetition rate
Solution Approach 1:
The patent applies dimensionality change by expanding the graphical password space from one-dimensional point sequences to multi-dimensional graphical configurations. The system utilizes spatial relationships, geometric transformations, color variations, and hierarchical structures to create passwords that exist in multiple dimensions. This dramatically increases the number of possible password combinations while maintaining relatively simple individual graphic structures.

AI summary
The present application provides a dynamic graphical password-based network registration method and system. The method includes: a server receives a registration request transmitted by a client, selects positioning factors from a positioning factor library based on a structure of a full-element dynamic factor table, generates positioning factor strings, and transmits the generated positioning factor strings to the client; the client generates full-element dynamic factor tables based on the structure of the full-element dynamic factor table and the positioning factor strings, wherein a user inputs two dynamic graphical passwords through the full-element dynamic factor tables, and transmits registration information including a user name and the positioning rules corresponding to the dynamic graphical passwords to the server; wherein if the registration information is correct, the positioning rule in the registration information is used as the password of the user. In the method, the input dynamic graphical password is used as the password stored for the user, which is securer, easy to remember, and hard to crack as compared with a conventional password consisting of fixed numerals or characters.
