Image-Based Login System for Pen-Computing Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pen-based computing systems face difficulties in user authentication due to the lack of convenient keyboard access, leading to frustration and security compromises, as users struggle to input secure information efficiently.
Innovation Solution
Implementing an image or pictographic-based login procedure that involves displaying images on a screen, receiving user inputs via electronic ink, and determining if they correspond to acceptable authentication inputs, allowing secure access when correct inputs are provided.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keyboard input is used for password entry, then security can be maintained through random character strings, but user convenience deteriorates due to the lack of keyboard accessibility in pen-based systems
Solution Approach 1:
The patent replaces the mechanical keyboard input system with a graphical interface system that accepts pen-based electronic ink input. Instead of requiring physical keyboard interaction, the system displays graphical elements and accepts drawing inputs, substituting the mechanical input method with a graphical-digital hybrid approach that works naturally with pen-based computing systems.
Solution Approach 2:
The patent changes the input parameter from discrete keyboard characters to continuous graphical drawings. By transforming the authentication input from a sequence of discrete key presses to a continuous electronic ink drawing, the system adapts the authentication mechanism to match the natural interaction mode of pen-based systems, thereby improving ease of operation while maintaining security through sophisticated drawing analysis.
2Ease of operation
If easy-to-remember passwords are used, then user convenience improves, but security deteriorates due to susceptibility to cracking
Solution Approach 1:
The patent introduces an intermediary graphical representation layer between the user's memory and the authentication system. Instead of directly entering a password, the user draws a graphical representation that serves as an intermediary - a visual mnemonic that is easy to remember but transforms into a complex authentication pattern that is difficult to crack, thus bridging the gap between memorability and security.
Solution Approach 2:
The patent uses copying by creating a graphical copy or representation of the authentication data. Rather than storing and processing plain text passwords, the system stores graphical drawings that are visual copies of the authentication information. These graphical copies are easy for users to remember visually but provide enhanced security through their complexity and resistance to traditional password cracking methods.
3Ease of operation
If pen-based input is used for authentication, then ease of operation improves by eliminating keyboard requirements, but device complexity increases due to the need for image processing and recognition systems
Solution Approach 1:
The patent extracts the authentication logic from the traditional keyboard-input-processing chain and isolates it into a separate graphical processing module. By taking out the password verification function and replacing it with dedicated image recognition and drawing analysis components, the system manages complexity through functional separation, allowing pen-based input convenience while organizing the sophisticated processing requirements into distinct, manageable modules.

AI summary
Image based login procedures for computer systems include: (a) displaying a first image on a computer screen; (b) receiving user input indicating a portion of the first image; (c) determining if the user input corresponds to a first acceptable user input for user authentication; and (d) proceeding with the authentication procedure when this user input corresponds to the first acceptable user input for user authentication. Additionally or optionally, when proceeding with this authentication procedure, the systems and methods further may include: displaying a second image on the screen; receiving new user input indicating a portion of the second image; and determining if this new input corresponds to a second acceptable user input for user authentication.
