POS Terminal Risk Scoring via Mobile Location Analysis

The patent introduces geographic location data as an intermediary verification element. Instead of relying solely on mobile terminal identifiers and PINs, the system uses the geographic location of the mobile terminal as a mediating factor to verify the authenticity of the POS terminal. This intermediary layer helps distinguish legitimate transactions from fraudulent ones by checking whether the mobile terminal's location is consistent with the expected location of the POS terminal, thereby improving reliability while maintaining ease of operation.

The patent changes the parameter used for verification from static mobile terminal identifiers to dynamic geographic location data. By incorporating location-based parameters into the risk scoring system, the patent enhances reliability without requiring complex hardware modifications. The system processes location data that is already available from mobile terminals and combines it with transaction information to generate risk scores, avoiding the need for additional complex devices or infrastructure.

The patent applies partial verification by not requiring all transactions to undergo the same level of scrutiny. Instead, the system generates risk scores for all transactions but only applies additional verification controls to transactions with high risk scores. This partial action approach maintains productivity for low-risk transactions while enhancing reliability for suspicious transactions, avoiding the need to slow down all transactions uniformly.
