Transaction Verification Using Social Network Verifier Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fraud detection systems struggle with transactions in the 'grey zone', requiring manual intervention due to indeterminate fraud status, leading to false positives and increased operational costs.
Innovation Solution
A method and system utilizing social network analysis to identify and propose trusted contacts as candidate verifiers for transactions, leveraging supervised learning to categorize transactions and match them with closest social network contacts for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used for grey zone transactions, then fraud detection accuracy is improved, but operational costs and processing time increase
Solution Approach 1:
The patent introduces social network contacts as intermediary verifiers between the automated fraud detection system and manual human review. These contacts serve as a middle layer that can automatically verify grey zone transactions, reducing the need for costly manual intervention while maintaining high detection accuracy through trusted social connections
Solution Approach 2:
The system enables self-service verification by allowing transaction owners to pre-designate social network contacts who can automatically verify transactions on their behalf. This eliminates the need for manual bank intervention in grey zone cases, as the verification process is handled autonomously by trusted contacts within the social network
2Measurement precision
If social network analysis is implemented, then false positives are reduced, but system complexity increases
Solution Approach 1:
The system performs preliminary action by having transaction owners pre-designate their social network contacts and define verification rules before any transactions occur. This advance setup creates a ready-to-use verification framework that simplifies real-time processing, as the system only needs to match transactions with pre-configured contacts rather than analyzing social networks from scratch for each transaction
Solution Approach 2:
The patent segments the fraud detection system into distinct modules: automated fraud scoring, social network contact matching, and manual review triggering. This segmentation allows each component to operate independently with specialized logic, reducing overall system complexity while improving verification precision through targeted social network analysis
3Device complexity
If traditional fraud detection is used, then system simplicity is maintained, but false positives increase
Solution Approach 1:
Social network contacts serve as intermediary verifiers that bridge the gap between simple automated detection and complex manual review. These intermediaries provide an additional verification layer that reduces false positives without requiring complete system redesign, maintaining relative simplicity while improving reliability
Solution Approach 2:
The patent makes the fraud detection system multi-functional by enabling it to handle both traditional automated detection and social network-based verification through a unified platform. This universality allows the system to maintain simplicity for clear-cut cases while automatically engaging social network verification for ambiguous transactions, improving overall accuracy without proportionally increasing complexity
Data Source
AI summary
A method, computer program product, and computer system are provided for verifying transactions. The method includes analyzing past transactions and categorizing the transactions into multiple categories; analyzing a social network of a transaction owner to identify a set of closest social network contacts for the transaction owner for each transaction category; and proposing the set of closest social network contacts as candidate transaction verifier contacts to be used by a transaction verifying entity for incoming transactions of the transaction category by the transaction owner to the transaction verifying entity.
