Spoofed Webpage Detection via Imperceptible Pixel Color Shifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spoofed webpages have become increasingly difficult to detect due to their similarity in aesthetics and design to legitimate pages, making it challenging to distinguish between authentic and fraudulent websites.
Innovation Solution
A system that generates or modifies graphical representations on webpages, which are periodically changed in a way that is imperceptible to users but detectable by user devices, allowing for the verification of a webpage's legitimacy by comparing captured images with stored data from a server device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spoofed webpages use the same aesthetics and design as legitimate webpages, then the visual similarity increases making spoofing more convincing, but the ability to detect spoofing decreases
Solution Approach 1:
The patent applies color changes by modifying the graphical representation through pixel value alterations that are imperceptible to human users but detectable by automated systems. The server device generates modified graphical representations with subtle color variations that maintain visual authenticity while enabling technical detection of spoofed webpages.
Solution Approach 2:
The patent introduces an intermediary detection mechanism between the user and the webpage content. A user device captures images of the webpage and compares them against stored reference images, acting as an intermediary layer that detects spoofing without affecting the user's visual experience of the webpage.
2Difficulty of detecting and measuring
If graphical representations are periodically changed to enable detection, then spoofing detection capability improves, but user perception of stability decreases
Solution Approach 1:
The patent applies parameter changes by systematically varying parameters such as pixel values, color intensities, and graphical representation characteristics over time. These parameter changes are controlled to remain within thresholds that preserve visual stability for users while enabling detection systems to identify and verify webpage authenticity through comparative analysis.
Data Source
AI summary
Methods and systems are provided to determine the legitimacy of a website. Such a website may include a graphical representation. The graphical representation may be periodically updated. A user device accessing the website may obtain data directed to the graphical representation at the time that the user device is accessing the website. The graphical representation may be compared to the data and legitimacy of the website may be determined through analysis of the graphical representation displayed on the website.
