Electronic Authorization Tokenization for Open-Network Payment Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database systems face challenges in securing confidential information stored on open networks, particularly when this information is used temporarily and then stored for future use, as they often lack the resources for active monitoring and high-level security measures.
Innovation Solution
An electronic authorization system that generates a unique encrypted identifier for transaction data, allowing confidential information to be replaced in databases, thereby preventing its storage in accessible open networks, and enabling secure data processing without direct access to proprietary information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If confidential information is stored in databases accessible over open networks, then data accessibility and operational efficiency are improved, but security risks and vulnerability to third-party attacks increase
Solution Approach 1:
The patent creates token copies that represent confidential payment card data. These tokens are stored in databases accessible over open networks, while the actual confidential data remains protected. The token serves as a functional copy that can be used for processing without exposing the sensitive information, thereby maintaining data accessibility while eliminating security risks associated with storing actual confidential data in accessible databases.
2Reliability
If high-level security measures and active monitoring are implemented, then security protection is improved, but system complexity and operational costs increase
Solution Approach 1:
The patent extracts the security burden from the overall system by removing confidential data from accessible databases entirely. Instead of implementing complex security measures to protect confidential data, the system stores only token copies that have no sensitive information. This extraction approach achieves high security protection without requiring complex security infrastructure, active monitoring, or additional security personnel, as the databases simply do not contain protectable confidential information.
Data Source
AI summary
An electronic authorization system comprising a data source system configured to transmit transaction data. A secure data system is coupled to the data source system over an open network, the secure data system is configured to receive the transaction data from the data source system, generate a unique encrypted identifier for the transaction data and to transmit the unique encrypted identifier to the data source system. The data source system is configured to receive the unique encrypted identifier and replace payment card data associated with the transaction data in a database with the unique encrypted identifier.
