Transaction Intermediary Encryption for E-commerce Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-commerce encryption methods fail to adequately secure sensitive information during online transactions, exposing user data to potential breaches and compromising privacy.
Innovation Solution
A transaction intermediary system that encrypts transaction information on the client device using a PGP encryption module, routes the encrypted package to a transaction processor for decryption and validation, and generates an electronic voucher for subsequent retail transactions, maintaining user privacy by minimizing exposure of sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional e-commerce encryption methods are used, then transaction processing is simplified, but security of sensitive information is compromised
Solution Approach 1:
The patent introduces an encryption module as an intermediary component between the form interface and the transaction processor. This module acts as a mediator that automatically encrypts sensitive information (credit card numbers, addresses, phone numbers) before transmission, while maintaining the existing e-commerce workflow. The intermediary approach allows security enhancement without requiring complex system-wide changes.
Solution Approach 2:
The encryption of sensitive information is performed preliminarily - before the transaction data is transmitted to the processor. By encrypting the data in advance during the form submission phase, the system ensures security is built into the data flow from the start, preventing exposure during transmission and processing while maintaining simplicity in the overall architecture.
2Reliability
If sensitive information is transmitted in plain text, then transaction processing is fast and simple, but user privacy is compromised
Solution Approach 1:
The encryption module serves as an intermediary that automatically transforms plain text sensitive information into encrypted format during the natural flow of transaction processing. This intermediary operation adds minimal overhead while ensuring user privacy is protected throughout the transaction lifecycle, without requiring manual intervention or complex timing coordination.
3Reliability
If encryption is implemented on the server side, then security is improved, but client device functionality is reduced
Solution Approach 1:
The patent segments the encryption functionality from the server and places it on the client device. This segmentation allows the client device to independently encrypt its own data before transmission, maintaining autonomy and functionality while improving security. The encryption module resides on the client side, enabling local encryption operations without requiring server-side cryptographic infrastructure.

AI summary
A transaction intermediary configured to receive a transaction request, enable the input of transaction information, receive a transaction package including the inputted transaction information, route the transaction package to a processing location, receive an indication that the transaction package has been processed, and generate an electronic voucher in response to the indication.
