Geographic IP Location Authentication for Stolen Passwords
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unauthorized access to network accounts using stolen passwords remains a significant issue, with thieves often gaining access by exploiting geographic locations or using compromised IP addresses.
Innovation Solution
A method that correlates IP addresses with geographic locations to determine access permissions, combining this with cookie validation and biometric information to ensure secure authentication, including the use of a database to match IP addresses with geographic data and issuing challenges for unapproved locations, and refreshing login keys for approved access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional username and password authentication is used, then ease of operation is improved, but security against stolen password attacks deteriorates
Solution Approach 1:
The patent adds geographic location as a new dimension to the authentication process. Instead of relying solely on username and password, the system now considers the user's geographic location (derived from IP address) as an additional authentication factor. This dimensional addition allows the system to detect and block unauthorized access attempts from foreign locations while maintaining easy operation for legitimate users in approved locations.
2Reliability
If geographic location verification is added to authentication, then security is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary action by pre-approving geographic locations for each user before authentication is needed. During setup, the system identifies and stores the user's approved locations. During actual authentication, the system only needs to check whether the current IP address matches one of the pre-approved locations, significantly simplifying the runtime complexity while maintaining strong security.
3Reliability
If IP address correlation with geographic location is implemented, then unauthorized access detection is improved, but loss of time increases due to additional verification steps
Solution Approach 1:
The system applies partial action by performing geographic location verification selectively rather than for every authentication attempt. The system can quickly determine whether to perform full verification based on initial checks, and only conducts the complete IP-to-location correlation and comparison process when necessary. This reduces the average time loss while maintaining effective unauthorized access detection.
Data Source
AI summary
The geographic location of a computer attempting to gain authentication to a server is obtained using the IP address of the computer, with authentication being denied if the geographic location is not approved.
