Email Sender Address Switching in Shared Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses in shared environments, such as offices, often display generic transmitter information in the From/Sender field of emails, making it difficult to identify the actual sender, which is undesirable for privacy and security reasons.
Innovation Solution
An image processing apparatus with a controller that allows flexible setting of the From/Sender field by enabling priority setting to display the logged-in user's information or apparatus transmitter information, based on user authentication and SMTP settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If generic transmitter information is displayed in the From/Sender field, then apparatus security is maintained, but sender identification capability deteriorates
Solution Approach 1:
The system dynamically switches between displaying generic transmitter information and logged-in user information based on authentication status and priority settings. When a user logs in and priority setting is enabled, the system transitions to displaying user-specific information; otherwise, it maintains generic apparatus information, thus adapting the display behavior to current operational conditions
Solution Approach 2:
The system applies different quality levels of information display to different operational contexts. For authenticated users with priority setting enabled, high-quality user-specific information is displayed; for other cases, standard generic apparatus information is displayed, ensuring appropriate information quality for each scenario
2Loss of information
If logged-in user information is always displayed in the From/Sender field, then sender identification capability is improved, but apparatus security and flexibility deteriorate
Solution Approach 1:
The system employs dynamic control logic that evaluates authentication status and priority setting configuration before determining what information to display. This prevents unconditional display of user information, maintaining security by only showing user-specific data when appropriate conditions are met
Solution Approach 2:
The system changes the display parameter (transmitter information type) based on authentication status and priority setting configuration. By conditionalizing the information display parameter, the system maintains security while enabling sender identification when needed
3Adaptability or versatility
If priority setting function is added to switch between user information and apparatus information, then flexibility is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary authentication and priority setting configuration before e-mail transmission. By pre-determining the appropriate transmitter information based on user login status and priority settings, the control logic becomes more straightforward, reducing operational complexity during actual mail sending
Solution Approach 2:
The authentication mechanism serves multiple functions: it verifies user identity, determines display priority for the From/Sender field, and controls overall system access. This multi-functionality reduces the need for separate dedicated mechanisms, thereby limiting the increase in device complexity

AI summary
An image processing apparatus comprising: one or more controllers that control transmission of electronic mail; a storage that stores user information of one or more users; and an authenticator that authenticates login of a user among the one or more users, wherein when priority setting of a transmission source address is enabled, the one or more controllers set the transmission source address, based on the user information of the user having logged in, and when the priority setting of the transmission source address is disabled, the one or more controllers set the transmission source address, based on transmitter information set for the apparatus.
