Email Communication Destination Conversion for Restricted Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods, such as PTL 1 and PTL 2, cannot convert communication destination information for various communication destinations into two-dimensional barcodes, making it difficult for users to access information from emails sent to terminals with restricted network communication.
Innovation Solution
An information conversion device and method that extracts mail-related information from received emails and converts communication destination information into readable format, allowing a first terminal not connected to the same network to read and communicate with the communication destination without network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication restrictions are implemented on the second network to protect confidential information, then security is improved, but the ability to access communication destinations from emails is worsened
Solution Approach 1:
The patent introduces a mail server as an intermediary that bridges the first network (with access to communication destinations) and the second network (with communication restrictions). The mail server receives emails containing communication destination information, converts this information into a readable format, and delivers it to terminals on the second network without requiring direct network communication between the restricted terminal and the communication destination
Solution Approach 2:
The patent transforms communication destination information (such as URLs or telephone numbers) into a different format that can be displayed and read by terminals on the restricted network. This parameter change allows the information to be accessible in the second network environment without violating communication restrictions
2Reliability
If the user manually inputs communication destination information to a first terminal, then communication with the destination is possible, but the operation complexity increases
Solution Approach 1:
The system performs automatic conversion of communication destination information into a readable format without requiring user intervention. The mail server automatically processes the information extraction and format conversion, eliminating the need for users to manually input data to a first terminal
Solution Approach 2:
The communication destination information is pre-converted into a readable format by the mail server before being delivered to the terminal on the second network. This preliminary action ensures that the information is already in the correct format when the user receives it, eliminating the need for subsequent manual input or conversion steps

AI summary
The present invention enables a user to easily reference information of a communication destination related to email-related information included in an email transmitted to a terminal connected to a network for which communication with another network is restricted. Prescribed email-related information is extracted from a received email, a conversion is carried out, from communication destination information of a communication destination related to the email-related information, into read information wherein the communication destination information can be read by a method not utilizing a network by a first terminal that is not connected to a network to which a second terminal receiving the email is connected, and an email to which the read information has been appended is output to the second terminal.
