Site Check Method Using Synchronized Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication systems fail to effectively differentiate between legitimate and illegitimate sites, particularly when a user accidentally accesses a phishing site that mimics the authentication system, requiring manual verification of complex URL strings.
Innovation Solution
A site check method involving a site server and a check server that synchronize their internal timers, allowing users to access both via personal computers and mobile devices, displaying unique check information to verify the legitimacy of the site by matching check information across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional user authentication systems use complex URL strings for site identification, then security verification capability is improved, but user operation ease deteriorates
Solution Approach 1:
The patent creates a simplified copy of the authentication system's verification capability that displays on the user's mobile device screen. Instead of requiring users to read and verify complex URL strings, the system generates a visual representation (check image) that mirrors the authentication state, allowing users to easily compare and verify legitimacy through visual matching rather than textual analysis.
2Measurement precision
If users manually verify complex URL strings to check site legitimacy, then verification accuracy is improved, but time consumption increases
Solution Approach 1:
The patent replaces the mechanical process of manual URL string verification with an automated image-based verification system. The authentication system automatically generates and displays a check image on the user's mobile device that visually represents the site's legitimacy status, eliminating the need for users to manually analyze complex URL strings and significantly reducing verification time while maintaining accuracy.
3Reliability
If authentication systems require users to analyze complicated letter and number strings, then security checking capability is improved, but system complexity increases
Solution Approach 1:
The patent utilizes visual elements including color-coded indicators and graphical representations to convey security status. The check image displays colored elements (such as green checkmarks or colored borders) that intuitively indicate legitimate versus illegitimate sites, replacing complex textual verification with simple visual cues that reduce system complexity while maintaining or enhancing security checking capability.

AI summary
According to the present invention there is provided a site check method for checking whether a predetermined site is legitimate or not, the method comprising the steps of providing a first server that is provided with site identification information and manages the predetermined site; and a second server that holds the site identification information provided to the first server and synchronizes its time with a time in the first server, receiving, by the first server, a first access from a first information terminal used by a user and creating first check information based on the time of the first access obtained from its own time information and the site identification information, displaying, by the first server, a login screen containing the created first check information on the first information terminal, receiving, by the second server, a second access from a second information terminal used by the user and creating second check information based on the time of the second access obtained from its own time information and the site identification information, and displaying, by the second server, the created second check information on the second information terminal. The site check method enables a user to easily check whether a site the user has accessed is legitimate or not.
