Data Transmission Apparatus User Authentication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission apparatuses face security issues despite user authentication, as they allow data transmission without ensuring secure limitations on transmission destinations.
Innovation Solution
A data transmission apparatus with a control unit that sets and enforces user authentication settings to restrict transmission destinations, using a transmission unit to send data only to authorized destinations based on authentication settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user authentication is performed and transmission settings are received from the mobile terminal, then data transmission can be executed readily, but security cannot be ensured as transmission destinations are not properly restricted
Solution Approach 1:
The patent segments the transmission destination management into two distinct parts: (1) reception of transmission settings from external terminals, and (2) registration of these destinations in the apparatus's destination management table. This segmentation allows the system to receive settings readily while maintaining security by controlling which received destinations are actually registered and used for transmission.
Solution Approach 2:
The patent introduces an intermediary control mechanism that mediates between receiving transmission settings from external terminals and actually using those destinations. The control unit acts as an intermediary that prevents direct registration of received destinations, instead requiring explicit user instruction for registration. This intermediary layer ensures security while maintaining ease of operation.
2Ease of operation
If transmission settings are readily accepted from external terminals, then data transmission operation is simplified, but transmission destinations may not be properly restricted leading to security issues
Solution Approach 1:
The patent applies preliminary action by requiring user confirmation before registering transmission destinations received from external terminals. The control unit is configured to prevent automatic registration and instead waits for explicit user instruction. This preliminary verification step ensures that only authorized destinations are registered, preventing unauthorized transmission access while maintaining simple operation flow.
Solution Approach 2:
The patent implements feedback by having the control unit monitor and control the registration process of transmission destinations. The system provides feedback to the user about received transmission settings and requires explicit confirmation before registration. This feedback mechanism ensures that unauthorized destinations are not registered while maintaining ease of operation for legitimate transmissions.
Data Source
AI summary
In a data transmission apparatus, when user information for a user of an external mobile terminal coincides with user information managed by the data transmission apparatus, data transmission is readily performed based on transmission settings received from the mobile terminal. This gives rise to an issue that security cannot be ensured although the use of data transmission is limited. The data transmission apparatus uses a user authentication function to set not to transmit data transmitted from the external mobile terminal. With such a configuration, data transmission can be prevented when a limitation is made on data transmission processing by using user authentication.
