Users may sometimes employ these technologies for privacy reasons or to circumvent location-based restrictions. In such cases, the strategy might mistakenly block or flag legitimate users.

Tactical implementation

1. Utilizing IP geolocation APIs or libraries: Integrate an IP geolocation API or library into your platform to gather location information from user IP addresses. Numerous third-party solutions offer accurate IP geolocation data, which can be seamlessly incorporated into your existing infrastructure.

   
   

2. Establishing threshold metrics for impossible travel: Set up rules to define implausible travel scenarios. For example, you might determine that it is impossible for a user to perform transactions or logins from locations more than x kilometers apart within y minutes. This threshold will depend on your specific use case and risk appetite.

   
   

3. Implementing real-time login analysis and alert systems: Develop a real-time login monitoring system that analyzes user login data against the established impossible travel thresholds. If a user's activity meets or exceeds these thresholds, an alert should be generated, prompting further investigation or immediate action, such as blocking the user's access or flagging the transaction as potentially fraudulent.

   
   

By implementing IP Geolocation and impossible travel detection, travel and ticketing professionals can better protect their platforms from SMS Pumping and other fraudulent activities. However, it is vital to remain aware of potential false positives and continuously refine the system to minimize user disruption while maintaining security.
