Image Forming Device User Authentication via External Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of user authentication in image forming devices connected to networks reduces the convenience of services by limiting the ability to perform remote jobs, as it may prevent the execution of tasks if the security measures are not valid.
Innovation Solution
An image forming device with a storage unit for user information and a control unit that authenticates and executes jobs based on user instructions received via an external network, ensuring only valid users can execute remote jobs, thereby maintaining security while allowing convenient service usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is introduced to improve security, then security is improved, but convenience of service is reduced
Solution Approach 1:
The patent introduces a server device as an intermediary that manages authentication information centrally. The image forming device communicates with this server to verify user credentials, allowing sophisticated security checks to be performed externally without adding complexity to the user interface or operation flow of the image forming device itself.
Solution Approach 2:
Authentication information is registered and stored in advance in a server device before actual job execution. When a user attempts to execute a job, the authentication has already been performed preliminarily through stored credentials, allowing quick verification without interrupting the user workflow. This enables security checks to be performed beforehand rather than blocking operations.
2Reliability
If user authentication is introduced to improve security, then security is improved, but service availability is reduced
Solution Approach 1:
The authentication system is designed to be universal, supporting multiple authentication methods (passwords, certificates, biometric data) and multiple types of jobs (scan, print, copy, fax). The server device stores and manages diverse authentication information types, allowing the same authentication infrastructure to support various service scenarios without limiting functionality.
Solution Approach 2:
The authentication system dynamically adapts to different users and job types. The server device can store and retrieve different authentication information based on user identity and job requirements. Authentication requirements can be adjusted dynamically based on the specific service being accessed, allowing the system to be both secure and flexible in supporting various services.

AI summary
An image forming device includes a storage unit and a control unit. The storage unit stores user information according to a specific device connected to an external network in advance. The control unit receives an execution instruction as an execution instruction of a job by a user indicated by the user information according to the specific device, if the execution instruction of the job is received from the specific device via the external network, and executes the job according to the execution instruction.
