Account Security Mediation for Tokenized Transaction Offers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction systems face barriers due to integration complexity and security concerns, particularly in managing client data and fraud prevention, which hinder efficient and secure transactions between clients, merchants, and lenders.
Innovation Solution
An account security system is implemented to authenticate merchant systems and handle promotions independently, using client tokens to secure transactions, isolating sensitive client data from merchant systems and facilitating seamless integration with merchant websites through modal interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If merchant systems handle promotions and transaction data directly, then integration with promotional systems is complex and requires significant system changes, but data security is improved by keeping sensitive data out of merchant systems
Solution Approach 1:
The patent introduces an account security system as an intermediary between merchant systems and promotional systems. This mediator handles sensitive client data and promotion management, allowing merchant systems to remain simple while maintaining security. The account security system receives authentication requests from merchants, validates them, and manages promotion data without requiring merchants to directly handle sensitive information.
2Productivity
If merchant systems process all transaction data including promotions, then functional capabilities are complete, but network efficiency decreases due to additional integration barriers and communications
Solution Approach 1:
The patent segments the transaction system into distinct functional components: merchant systems handle only authentication and basic transaction initiation, while the account security system handles promotion management and sensitive data processing. This segmentation improves network efficiency by reducing unnecessary communications between systems while maintaining complete functional capabilities through the coordinated work of specialized components.
3Reliability
If client data is shared with merchant systems for transaction processing, then transaction functionality is enabled, but fraud risk and security vulnerabilities increase
Solution Approach 1:
The patent uses tokenization to create secure copies of client data. Instead of sharing actual sensitive information with merchant systems, the system creates token representations that enable transaction processing without exposing real client data. These tokens can be used for authentication and promotion eligibility verification while maintaining the security of original client information.
Data Source
AI summary
Examples described herein include systems, methods, instructions, and other implementations for data security with integrated promotion systems. In one example, account security system receives a checkout communication that includes data describing a validated checkout system of a merchant system, where the checkout communication does not include a purchase promotion option. A client token is transmitted in response to an authentication that the checkout communication is from the validated checkout system, and an account communication including the client token and secure client information is received from a client device. A plurality of promotion options associated with the secure transaction is transmitted in response to the account communication, and a promotion selection for the secure transaction is received from the client device and not from the merchant system.
