Secure Report Generation in Payment Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Payment systems face challenges in securely transmitting and storing sensitive cardholder data across secure and unsecure devices, particularly in fueling environments, where existing solutions increase costs or introduce complexity, and unsecure methods like removable storage pose security risks.
Innovation Solution
A method and apparatus for securely transmitting and generating reports in a payment system, where a secure device connected to a host system encrypts and stores sensitive data, allowing authorized access through password protection and secure report generation, compliant with PA-DSS standards, without requiring additional hardware on unsecure devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensitive cardholder data is transmitted to unsecure devices for reporting purposes, then reporting functionality is enabled, but security compliance with PA-DSS standards is violated
Solution Approach 1:
The system segments data into sensitive cardholder data and non-sensitive report data. The secure device generates reports containing only non-sensitive information (masked account numbers, transaction amounts, dates) that can be safely transmitted to unsecure POS devices for reporting purposes, while sensitive data remains isolated in the secure environment.
Solution Approach 2:
The secure device acts as an intermediary that receives sensitive cardholder data, processes it into secure report formats with masked information, and transmits only the secure version to unsecure devices. This intermediary process enables reporting functionality while maintaining security compliance by preventing direct transmission of sensitive data.
2Reliability
If a printer is installed within the secure environment to print reports containing account information, then secure reporting is achieved, but system cost increases
Solution Approach 1:
Instead of installing expensive printing hardware in the secure environment, the system creates a secure copy of the report data with sensitive information masked or encrypted. This secure copy is then transmitted to unsecure devices that already have printing capability, eliminating the need for additional secure printing hardware.
Solution Approach 2:
The secure device performs multiple functions: it generates reports, masks sensitive information, encrypts data, and transmits secure reports to unsecure devices. This multi-functionality eliminates the need for separate secure printing hardware, reducing overall system cost while maintaining secure reporting capabilities.
3Ease of operation
If removable storage devices are used to transfer account information, then data accessibility is improved, but security risks increase due to unsecure storage
Solution Approach 1:
The system changes the parameters of the data before storage by masking sensitive cardholder information (replacing account numbers with asterisks) and encrypting the report data. This transformation allows the data to be stored on unsecure removable media while maintaining security, as the stored data no longer contains sensitive information in readable form.
Data Source
AI summary
A system, device, and method for generating and transmitting secure reports or documents in a retail environment or payment system comprising both secure and unsecure portions, where users of the unsecure portions may require access to sensitive information stored by the secure portions for various purposes, such as reporting, accounting, or reconciliation.
