Universal Chargeback Database for Cross-Issuer Fraud Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems suffer from significant monetary losses due to chargeback fraud committed by customers, which is not well documented and imposes costs on the system that are not borne by the perpetrators.
Innovation Solution
A universal chargeback database is implemented, accessible to multiple card issuers, storing unique customer identifiers and historical chargeback data to assist in determining whether to issue new cards or approve chargeback requests, using autonomous computer algorithms for scalability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a universal chargeback database is implemented to reduce chargeback fraud, then chargeback fraud is reduced and system security is enhanced, but device complexity and system infrastructure requirements increase
Solution Approach 1:
The patent consolidates chargeback data from multiple card issuers into a single universal database, merging previously siloed information systems. This allows all participating issuers to access shared chargeback history, enabling more accurate fraud detection while distributing the benefits across the entire system rather than requiring each issuer to build independent solutions.
Solution Approach 2:
The universal chargeback database serves multiple functions: storing chargeback records, enabling fraud pattern analysis, supporting risk assessment for new card issuances, and providing historical data for dispute resolution. This multi-functional system replaces what would otherwise require separate specialized systems for each function.
2Measurement precision
If historical chargeback data is shared across multiple card issuers, then fraud detection accuracy is improved, but information security and data privacy risks increase
Solution Approach 1:
The patent introduces a neutral intermediary entity (the universal database managed by a neutral party) that handles the storage and sharing of sensitive chargeback data. This intermediary structure allows issuers to benefit from shared information without directly exposing their proprietary data to competitors, as the neutral intermediary controls access and maintains data governance policies.
Solution Approach 2:
The system creates standardized copies of chargeback records that can be shared across the network without transferring original sensitive data. Each issuer receives relevant information in a standardized format that preserves fraud detection capabilities while maintaining data security through controlled replication rather than direct data sharing.
Data Source
AI summary
A method and system are provided for issuing new financial cards to customers and for determining whether to approve chargeback requests made by customers. The method and system utilize a chargeback database that is accessible by multiple card issuers. The chargeback database uses customer identifiers that are unique for each customer in the database. Card issuers are able to search the database to retrieve historical chargeback data involving a particular customer. The historical chargeback data includes chargeback requests made to any card issuer with access to the database.
