Dynamic Card Verification Value Delivery via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The persistence of fraud and counterfeiting in financial transactions, particularly with skimming of magnetic stripe data in both static and contactless card environments, where traditional methods are ineffective in preventing fraudulent activities due to the passive nature of magnetic stripes and the ease of data interception in wireless transactions.
Innovation Solution
Implementing a dynamic card verification value (dCVV) system that generates and provides a dynamically changing verification value, which is securely received by consumers through their personal communication devices, ensuring authenticity and preventing fraudulent use, while minimizing disruptions to the transaction process and leveraging existing network infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dynamic card verification value (dCVV) is generated and securely received by the consumer, then transaction security is improved, but the inconvenience of receiving and using the dCVV increases
Solution Approach 1:
The patent uses a personal communication device (mobile phone) as an intermediary to deliver the dCVV to the consumer. Instead of requiring direct interaction with complex verification systems, the consumer simply receives the dCVV as a text message or notification on their existing mobile device, significantly reducing the inconvenience while maintaining security
Solution Approach 2:
The system automatically generates, transmits, and manages the dCVV without requiring active consumer participation in the verification process. The consumer's existing mobile device and communication channels are leveraged to deliver the verification value, eliminating the need for consumers to perform additional security steps
2Ease of operation
If contactless cards are used to enable wireless transactions, then transaction convenience is improved, but the vulnerability to skimming increases
Solution Approach 1:
The patent implements a dynamic verification value that changes with each transaction instead of using static card data. The dCVV is generated dynamically based on transaction parameters and is unique to each transaction, making it impossible for skimmers to copy and reuse the same verification value across multiple transactions
Solution Approach 2:
The system changes the verification parameter from static magnetic stripe data or fixed CVV codes to dynamically generated values that vary with each transaction. This parameter transformation makes the verification mechanism resistant to skimming while maintaining the convenience of contactless transactions
3Adaptability or versatility
If magnetic stripe data is used for transactions, then backward compatibility is improved, but the data can be perfectly copied without difference
Solution Approach 1:
The system performs preliminary verification by generating a fresh dCVV before each transaction occurs. This advance preparation ensures that even if magnetic stripe data is skimmed, the verification value used for authentication is already unique and cannot be copied, thereby maintaining security while preserving compatibility with existing magnetic stripe cards

AI summary
Embodiments of the invention are directed to methods, systems, and computer program products pertaining to obtaining, providing, and using dynamic card verification values for portable consumer devices, such as credit cards and debit cards. An exemplary method comprises receiving, at a server, a request for a device verification value for a portable consumer device associated with a user; obtaining, at the server, a datum indicative of a device verification value for a portable consumer device; and sending, from the server, the datum to at least one of a phone number or network address of a personal communication device associated with the user.
