Multi-Parameter Identity Verification for Financial Fraud Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Card-not-present and card-present financial fraud continues to grow despite various fraud detection solutions, as existing methods fail to effectively verify the identity of cardholders in online transactions, particularly using mobile directory numbers and email addresses.
Innovation Solution
A system that utilizes mobile directory numbers and email addresses to validate the identity of cardholders by analyzing wireless device location data, supplementary subscription data, and IP address data, generating an identity risk value to detect fraudulent transactions and prevent identity theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fraud detection solutions (AVS, VAA, SecureCode) are used for card-not-present transactions, then some level of fraud protection is provided, but online fraud continues to grow at a rapid pace
Solution Approach 1:
The patent changes the verification parameters from traditional card-based verification (AVS, VAA) to multi-parameter verification including mobile device identifiers, email addresses, IP addresses, location data, and device characteristics. This parameter expansion enables more effective fraud detection by creating a comprehensive identity profile that is difficult for fraudsters to replicate
Solution Approach 2:
The verification system is segmented into multiple independent verification components: mobile device verification, email verification, IP address verification, location verification, and device fingerprinting. Each component verifies a specific aspect of the user's identity, and together they form a robust multi-layered security approach that addresses the limitations of traditional single-method verification
2Measurement precision
If multiple verification parameters (mobile device ID, email, IP address, location) are collected and analyzed, then identity verification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal verification platform that handles multiple verification types (mobile, email, IP, location, device characteristics) through a single integrated system. This multi-functional approach consolidates what would otherwise be separate verification systems, managing complexity through unification while maintaining high verification accuracy through comprehensive parameter analysis
Solution Approach 2:
The system introduces intermediary components including verification servers, databases for storing verification data, and communication protocols that mediate between various verification sources and the transaction processing system. These intermediaries manage the complexity of multi-parameter verification by providing standardized interfaces and centralized data management
3Reliability
If mobile directory numbers and email addresses are used as unique identifiers for cardholders, then identity verification capability is improved, but vulnerability to identity theft and fraudulent account establishment increases
Solution Approach 1:
The patent creates a composite identity verification system that combines multiple identification parameters (mobile device ID, email address, IP address, location data, device characteristics) into a unified identity profile. This composite approach ensures that compromise of any single parameter does not result in complete identity theft, as the system requires consistency across all parameters to verify identity
Solution Approach 2:
The system implements feedback mechanisms where verification data is continuously collected, analyzed, and used to update risk assessments. When anomalies are detected in any verification parameter, the system provides feedback to request additional verification or reject the transaction, creating a dynamic security response that adapts to potential identity theft attempts
