Mobile Gambling Access Verification Using Multi-Level Location Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile gaming systems struggle to accurately determine the location of devices accessing gaming services, particularly when using IP addresses, leading to potential unauthorized access from unauthorized locations.
Innovation Solution
A multi-level location determination system that includes trusted IP-based location, high confidence IP-based location, and low confidence IP-based location, with secondary location verification methods such as geofencing and GPS, to ensure accurate location determination and authorization for gaming services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IP address-based location determination is used for mobile gaming access, then access convenience is improved, but location accuracy deteriorates leading to potential unauthorized access
Solution Approach 1:
The location verification process is segmented into multiple levels: first-level IP address-based location determination for quick access, and second-level alternative location determination methods (GPS, cell tower triangulation, Wi-Fi positioning) for verification when confidence is low. This segmentation allows the system to maintain access convenience while improving location accuracy through selective multi-method verification.
Solution Approach 2:
A confidence level mechanism acts as an intermediary between IP address-based location determination and access authorization. The system calculates a confidence level based on IP address reliability indicators, and this intermediary confidence assessment determines whether to proceed with IP-based access or require alternative location verification methods, thus balancing convenience and accuracy.
2Measurement precision
If multiple location verification methods are implemented, then location accuracy is improved, but system complexity increases
Solution Approach 1:
The system dynamically selects and applies location verification methods based on real-time confidence level assessments. Instead of always using all verification methods, the system adaptively determines the appropriate verification level needed for each access request, reducing unnecessary complexity while maintaining high location accuracy when required.
Solution Approach 2:
Different location verification methods are applied locally based on specific conditions: IP address-based determination is used for high-confidence cases, while alternative methods (GPS, cell tower triangulation, Wi-Fi positioning) are selectively applied for low-confidence cases. This localized application of verification methods reduces overall system complexity by avoiding universal multi-method verification for all access requests.
3Reliability
If IP address confidence thresholds are set high, then unauthorized access prevention is improved, but legitimate access rate decreases
Solution Approach 1:
The system implements feedback through confidence level calculation and threshold comparison. When an IP address-based location determination falls below the confidence threshold, the system provides feedback by triggering alternative location verification methods. This feedback mechanism ensures high reliability for unauthorized access prevention while maintaining high legitimate access rates by allowing low-confidence requests to proceed with additional verification rather than immediate rejection.
Solution Approach 2:
The system performs preliminary confidence assessment of IP address-based location determination before final access authorization. This preliminary action identifies low-confidence requests that require alternative verification methods, allowing the system to prepare appropriate verification steps in advance and process legitimate users efficiently without compromising security.

AI summary
Techniques for multi-level device verification for mobile gambling applications are described. For example, when an application executing on a smartphone attempts to access a gambling activity of the gambling service, the location of the smartphone is attempted to be determined based on GPS data. If the GPS data is not determinable, the location of the smartphone may be determined using another technique, such as triangulation. Based on the determined location, the application receives an indication that the smartphone is in a U.S. state where gambling is allowed, and the application is enabled to access the gambling service to engage in the gambling activity.
