Image-Based Authentication Using Grid Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional password-based user authentication systems are vulnerable to fraud, especially in public spaces and over the internet, as users often have to remember multiple complex passwords, making them inconvenient and susceptible to theft.
Innovation Solution
An image-based authentication system where users select verification images and perform actions on target locations, with encryption of these actions' positions using a grid system, enhancing security by making passwords more difficult to misappropriate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password-based authentication is used, then user authentication can be performed, but the system is vulnerable to fraud and password theft in public spaces and over the internet
Solution Approach 1:
The patent replaces traditional text-based password input with image-based authentication. Instead of typing passwords that can be captured through malware or shoulder surfing, users interact with images by selecting target locations and performing actions on them. This substitution of mechanical input method fundamentally reduces the vulnerability to password theft while maintaining authentication reliability.
Solution Approach 2:
The patent transforms the authentication parameter from text strings to image coordinates and action sequences. By changing the fundamental nature of the password from alphanumeric characters to spatial positions and gestures on images, the system eliminates the primary attack vectors targeting traditional passwords while preserving the core authentication function.
2Reliability
If multiple complex passwords are required for different applications, then security is improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The patent creates a universal image-based authentication system that can be applied across multiple applications and platforms. The same image interaction paradigm works for local applications, web applications, and mobile apps, eliminating the need for users to learn and remember different complex passwords for each application while maintaining strong security.
Solution Approach 2:
The patent divides the authentication process into distinct actionable components: selecting target locations on images, performing actions on those locations, and sequencing these actions. This segmentation makes the authentication process more manageable and easier to remember compared to complex multi-component passwords, while still providing equivalent or superior security.
3Ease of operation
If text-based passwords are used, then authentication can be performed, but they are vulnerable to misappropriation by thieves through malware or observation
Solution Approach 1:
The patent replaces the mechanical act of typing text passwords with graphical interactions involving image selection and gesture input. This substitution eliminates the vulnerability to keyloggers and malware that capture text input, while the visual nature of image-based authentication also makes it harder for observers to capture through shoulder surfing or screen recording.
Data Source
AI summary
In computer-based user authentication, a user may establish or enhance security for a component of a multi-component password by performing a security operation on a selected component of the password. The security operation may comprise encrypting the selected component. The password may be an image-based password and security operation may be encrypting information related to positions of at least one target location on a verification image.
