Authentication Handover in Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image processing apparatuses, implementing a handover function for authentication information from a login application to another application, such as a transmission application, can be redundant if the transmission application already has a handover function, leading to unnecessary duplication of functionality.
Innovation Solution
An image processing apparatus with a processor that enables a first application for user authentication and sets an authentication function for a second application to ON, allowing the handover of authentication information from the first application to the second application without requiring an explicit handover function in the login application, utilizing the existing handover function of the transmission application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a handover function for authentication information is implemented in the login application, then authentication information can be handed over to other applications, but the device complexity increases due to redundant functionality
Solution Approach 1:
The patent applies universality by enabling the transmission application's existing handover function to serve dual purposes: both receiving authentication information from the login application and performing its original transmission authentication handover. This allows one function (the transmission application's handover function) to perform multiple roles, eliminating the need for a separate handover function in the login application while maintaining full authentication handover capability.
2Adaptability or versatility
If the authentication function is always enabled in the transmission application, then authentication information handover is always available, but it increases device complexity when the login application is not being used
Solution Approach 1:
The patent applies dynamics by making the authentication function setting in the transmission application changeable based on the operational state of the login application. The setting dynamically adjusts between ON and OFF states according to whether the login application is enabled, allowing the system to optimize between authentication handover availability and device complexity reduction based on current usage conditions.

AI summary
An image processing apparatus, if a login application (login app) is enabled, performs setting of an authentication function (authentication transmission) of a transmission application (transmission app). The image processing apparatus performs an ON or OFF setting of the authentication function (authentication transmission) which has a handover function for receiving authentication information, used for authentication by another application, that is handed over from the other application and using the handed over authentication information. The image processing apparatus, in accordance with the login app being enabled, by setting the authentication transmission of the transmission app to ON, enables handover by the handover function of authentication information used by the login app to the transmission app.
