Temporal CVV2 Generation for Secure Online Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems do not allow customers to use their new credit cards for online transactions before receiving the physical card, posing a fraud risk and limiting immediate purchasing capabilities.
Innovation Solution
A system and method that generates a Temporal CVV2, a temporary three-digit number associated with a card number, which includes a validity parameter, allowing customers to make purchases before the physical card arrives, using a crypto generation processor and secure encryption protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an instant display of credit card and CVV2 is provided when account is approved, then customer convenience and productivity are improved, but fraud risk increases
Solution Approach 1:
The patent applies dynamics by transforming the static CVV2 into a dynamic temporal CVV2 that changes over time. The temporal CVV2 is generated with a validity period and expires automatically, making it useless for future fraudulent transactions. This resolves the contradiction by enabling immediate transaction capability while limiting the window for fraud through time-based validity.
Solution Approach 2:
The patent changes the parameter of CVV2 from static to temporal by adding a validity period parameter. The temporal CVV2 includes expiration time information that is verified during transaction processing. This parameter change allows immediate card usage while preventing fraud by ensuring the CVV2 is only valid within a specific time window.
2Ease of operation
If actual CVV2 is revealed along with PAN and expiry date, then customer convenience is improved, but security is worsened
Solution Approach 1:
The patent creates a temporary copy of the CVV2 function rather than revealing the actual CVV2. The temporal CVV2 is a separate entity that mimics the authentication function but is distinct from the permanent card credentials. This allows customers to make online purchases without exposing the actual CVV2 stored on the physical card, maintaining security while enabling convenience.
Solution Approach 2:
The patent implements disposable temporal CVV2s that are generated for specific time periods or transactions and then expire. These temporary credentials are inexpensive to generate and replace, allowing the system to provide secure one-time or limited-use authentication codes that eliminate the need to store or repeatedly use the actual CVV2, thereby enhancing security while maintaining ease of operation.
3Reliability
If Temporal CVV2 is generated for each transaction request, then fraud risk is reduced, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-generating temporal CVV2s with embedded validity periods and transaction parameters before actual transactions occur. The system can pre-issue these temporary credentials to customers upon account approval, and the validation logic is pre-programmed into the crypto validation processor. This reduces fraud risk through pre-configured security measures while managing complexity through automated pre-processing.
Solution Approach 2:
The patent implements self-service through automated temporal CVV2 generation and validation. The crypto generation processor automatically creates temporal CVV2s with embedded expiration times, and the crypto validation processor automatically verifies them during transactions without requiring manual intervention. This automation reduces fraud risk through consistent application of security rules while managing system complexity through self-service processing.

AI summary
An embodiment of the present invention is directed to a Temporal CVV2 of CVV, which may be represented as a temporary three digit number generated using unique credentials associated with a card product. According to an embodiment of the present invention, the Temporal CVV2 may be generated for each transaction request or other defined set of transactions based on one or more factors, including time period/limit, usage, fraud/risk considerations. With this solution, a customer may request a new Temporal CVV2 each time a purchase is initiated. This may include online purchases, e-commerce transactions, manual link and provision requests, customer authentication for servicing channels, etc. An embodiment of the present invention seeks to mitigate risk and provide a safer and secure solution for customers while providing flexibility to make various purchases before a new card arrives.
