Fax Transmission Device Embedding Destination Data in Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fax transmission methods require cumbersome pre-registration procedures and risk leakage of transmission destination information, especially when converting fax data to electronic mail, due to the need for explicit dialing numbers and codes that are not directly related to the actual reception destination.
Innovation Solution
A transmission system that embeds transmission destination information as dot data within the image data, allowing it to be transmitted via fax communication, where the dot data is converted back into command characters to determine the transmission method, enabling secure and efficient routing without the need for explicit pre-registration or large barcode spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission destination information is embedded as dot data within image data, then security against information leakage is improved and space efficiency is improved, but the complexity of the transmission system increases due to the need for embedding and decoding mechanisms
Solution Approach 1:
The patent embeds transmission destination information (command characters) within the image data itself by converting characters to dot patterns that are interspersed with image pixels. The destination information is nested inside the image data structure, allowing both the image and routing information to be transmitted together through the same fax channel without requiring separate communication channels or complex external routing systems.
Solution Approach 2:
The patent changes the representation form of transmission destination information from human-readable text or barcodes to binary dot patterns that can be seamlessly integrated with image data. By converting command characters into sequences of dots (present or absent pixels), the system transforms routing information into a format that occupies minimal space within the image data structure while maintaining security and enabling automatic decoding at the receiving end.
2Adaptability or versatility
If pre-registration procedures are implemented in the transfer service system, then transmission routing control is improved, but the ease of operation deteriorates due to troublesome procedures and time consumption
Solution Approach 1:
The patent incorporates the transmission destination information directly into the image data before transmission, eliminating the need for separate pre-registration procedures. The command characters containing destination information are embedded in advance within the image data structure, so that when the fax is received, the destination can be immediately extracted and processed without requiring the receiving system to look up pre-registered information or perform complex routing queries.
Solution Approach 2:
The image data itself carries its own routing information through the embedded command characters. The transmission system becomes self-sufficient as the image data contains all necessary information for routing and transmission control within its own structure, eliminating the need for external pre-registration databases or complex transfer service system interventions.
3Ease of operation
If explicit dialing numbers and codes are used for fax transmission, then transmission routing is simplified, but the risk of information leakage increases and security deteriorates
Solution Approach 1:
The patent applies different representation qualities to different parts of the transmitted data. The transmission destination information is encoded in a specialized dot pattern format that is locally distinct from regular image content. This local differentiation allows the routing information to be securely embedded within the image data while maintaining the simplicity of fax transmission, as the receiving system can locally identify and extract the dot-patterned command characters without exposing them in readable form during transmission.

AI summary
A transmission device includes an obtainment unit configured to obtain a fax number of a relay device and transmission destination information that determines a transmission destination; a scanner unit configured to scan a script of a transmission target so as to generate image data of the script; and a processor configured to execute a process including: generating a command for transmitting the image data to the transmission destination by using the obtained transmission destination information; converting each character constituting the command into a binary number; adding, to the image data, dot data represented by a dot that corresponds to the binary number; and transmitting the image data to which the dot data has been added, to the relay device via fax communication.
