Authenticated Random Verification Codes for Transaction Card Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction card systems are vulnerable to misappropriation of transaction card information, leading to illicit purchases and burdensome reporting processes for cardholders.
Innovation Solution
A transaction platform generates a random verification code based on user profile information, authenticates it, and provides it to the user device for secure transactions, validating the transaction with the merchant device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transaction card systems are used, then transaction card information can be stored on the card, but the system becomes vulnerable to misappropriation and requires burdensome reporting processes
Solution Approach 1:
The verification code is extracted from the transaction card and transferred to a remote server. The server generates verification codes dynamically based on transaction details rather than storing them on the card, eliminating the vulnerability of stored card information while maintaining security functionality.
Solution Approach 2:
A remote server acts as an intermediary between the transaction card and the verification process. The server receives card information, generates verification codes, and validates transactions without requiring direct access to stored card data, thereby enhancing security and simplifying the reporting process for cardholders.
2Productivity
If verification codes are generated manually or stored on cards, then transaction validation can be performed, but computing resources are consumed and human intervention is required
Solution Approach 1:
Verification codes are generated in advance by the server before transactions occur. The server pre-computes verification codes based on transaction details and stores them securely, allowing rapid validation during actual transactions without consuming significant computing resources at the time of validation.
Solution Approach 2:
The system automatically generates and validates verification codes without requiring human intervention. The server autonomously processes transaction validation by comparing generated codes with stored values, eliminating manual operations and reducing computing resource consumption while maintaining high validation efficiency.

AI summary
A device receives, from a user device, a request to generate a verification code for a transaction associated with a user of the user device, and receives user profile information associated with a transaction card to be used for the transaction. The device generates a random verification code for the transaction based on the request and the user profile information, and authenticates the random verification code, based on the user profile information, to generate an authenticated random verification code. The device provides the authenticated random verification code to the user device, and receives transaction information, including the authenticated random verification code, from a merchant device associated with the transaction. The device validates the transaction based on the transaction information, and provides, to the merchant device associated with the transaction, information indicating that the transaction is validated.
