Point-to-Point Encryption Tokenization System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack robust security measures for protecting sensitive data, particularly card holder data, during transfer and processing across computing systems, which can lead to unauthorized access and data breaches.
Innovation Solution
A point-to-point encryption and tokenization system that includes a pin entry device for encrypting card holder data, a first computing system for receiving and transmitting encrypted data, and a second computing system with decryption, tokenization, and authorization modules to securely process and store the data, using multiple cryptographic techniques and segmented zones for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensitive data is transferred between computing systems without encryption, then data processing is simple and fast, but security is compromised and unauthorized access occurs
Solution Approach 1:
The system segments data processing into distinct zones (first computing system for encryption, second computing system for decryption and tokenization). Each zone handles specific operations with dedicated modules, isolating sensitive data handling to minimize exposure risks while maintaining overall system functionality.
Solution Approach 2:
A tokenization service acts as an intermediary between the first and second computing systems. The service generates tokens representing encrypted card holder data, enabling secure data exchange without directly transmitting sensitive information between systems, thus reducing security risks during transfer.
2Reliability
If card holder data is stored in plaintext, then data retrieval is fast and simple, but data breaches occur and sensitivity is compromised
Solution Approach 1:
Card holder data is encrypted at the point of entry using a pin entry device before being stored or transmitted. This preliminary encryption action ensures that data is protected from the outset, preventing unauthorized access while maintaining the ability to process data through proper decryption channels.
Solution Approach 2:
Instead of storing sensitive card holder data in plaintext, the system creates and stores tokens as copies that represent the encrypted data. These tokens can be processed and stored without exposing the actual sensitive information, reducing breach impact while enabling continued data operations.
3Reliability
If multiple encryption and tokenization steps are implemented, then data security is enhanced, but processing time and system complexity increase
Solution Approach 1:
The system merges encryption and tokenization operations into an integrated workflow where the tokenization service handles both encrypted data receipt and token generation in a coordinated manner. This combining of functions reduces redundant operations and optimizes processing flow while maintaining security robustness.
Solution Approach 2:
The system maintains continuous security protection through automated encryption at point of entry and ongoing tokenization, ensuring that data remains protected throughout the entire processing lifecycle without requiring repeated manual intervention or creating significant delays.
