Network Gateway Tokenization for Secure Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data security systems face challenges in securely transmitting sensitive information across networks without compromising compliance with regulations, as they often require handling and storing sensitive data, which can lead to compliance issues and data breaches.
Innovation Solution
A network-based messaging system that replaces sensitive information with tokens within messages, allowing the network gateway to process and forward the information securely, maintaining compliance by ensuring the sensitive information is not exposed to the sending party and is stored securely, with failover procedures for message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensitive information is transmitted directly from sending party to receiving party, then transmission simplicity is improved, but security and compliance are worsened
Solution Approach 1:
A network gateway is introduced as an intermediary component between the sending party and receiving party. The gateway receives messages containing tokens, replaces tokens with corresponding sensitive information, and forwards the messages to recipients. This intermediary approach maintains transmission simplicity for end users while ensuring security and compliance through centralized control of sensitive data handling.
2Reliability
If sensitive information is stored and handled by the network gateway, then security control is improved, but compliance risk is worsened
Solution Approach 1:
The system extracts sensitive information from the message transmission flow and stores it separately in a tokenization database managed by the network gateway. Only token references are transmitted in messages, while the actual sensitive data remains isolated in the gateway's secure storage. This extraction approach improves security control while reducing compliance risk by minimizing the exposure and handling of sensitive information.
3Reliability
If tokens are replaced with sensitive information at the network gateway, then security is improved, but system complexity is worsened
Solution Approach 1:
The network gateway automatically performs token replacement operations without requiring manual intervention or complex configuration. The gateway maintains an internal tokenization database that maps tokens to sensitive information, and the replacement process occurs transparently as messages pass through the gateway. This self-service approach improves security while keeping system complexity manageable through automation.
4Reliability
If the network gateway processes all messages through token replacement, then security consistency is improved, but processing time is worsened
Solution Approach 1:
Sensitive information is pre-tokenized and stored in the network gateway's database before message transmission occurs. When messages are sent, they contain pre-prepared tokens that simply need to be replaced with corresponding stored values. This preliminary tokenization action ensures security consistency while minimizing processing time during actual message transmission, as the replacement operation becomes a simple database lookup rather than complex processing.

AI summary
Embodiments of the present disclosure relate to network gateway based messaging systems and methods. Some methods include transparent message processing that includes receiving a message from a first party that includes a payload and a token. The token is associated with sensitive information. Next, the method includes replacing the token with the sensitive information within the message and forwarding the message with the sensitive information to a second party. The payload is unaffected by the token exchange process.
