Server Login Country Verification via IP SIM GPS Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video call services lack effective methods to restrict users from accessing services by faking their login country, which can lead to unfair access to country-specific benefits.
Innovation Solution
A server system that determines the login country of a terminal by analyzing IP address, SIM, and GPS information, comparing it with the country information provided during service subscription, and allowing or blocking access based on matching or non-matching results, with the option to request additional time and locale information for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video call service is provided without country verification, then service accessibility is improved, but service fairness deteriorates due to users faking login country to access country-specific benefits
Solution Approach 1:
The server performs preliminary verification of the terminal's login country against the beneficiary country before providing video call service. Country information is obtained in advance from multiple sources (IP address, SIM card, GPS) and compared with the beneficiary country stored in the user profile, preventing unauthorized access before it occurs
Solution Approach 2:
The patent introduces country verification as an intermediary mechanism between the terminal and video call service. The server acts as a mediator that checks whether the terminal's actual country matches the beneficiary country, controlling service provision based on this verification without affecting the terminal's ability to access the service when legitimate
2Measurement precision
If multiple country verification methods are used, then measurement precision of login country is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple country verification methods (IP address verification, SIM card country code verification, GPS location verification) into a unified verification system. The server integrates these different verification approaches and uses them collectively to determine the terminal's login country, improving accuracy while managing complexity through systematic integration
Solution Approach 2:
The verification system is designed to perform multiple functions using a single integrated mechanism. The server can verify country information through different methods (IP, SIM, GPS) and switch between them or use them in combination, making the verification system versatile and adaptable to different scenarios without requiring separate systems for each verification method

AI summary
A server may include a communication interface for receiving a log in request for a video call service from a terminal, and for receiving at least one information to be used to determine a country of a log in attempt from the terminal; a memory for storing country information received from the terminal when subscribing the video call service of the terminal; and a processor for determining the country of the log in attempt of the terminal based on the at least one information, comparing a prestored country information corresponding to the terminal with the determined country of the log in attempt, and allowing the log in of the terminal depending on a result of the comparison.
