Authentication Server Mediates Image Processing Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing devices face security compromises due to unrestricted access from external applications, making it difficult to maintain security without pre-registering information for all applications, especially with the increasing number of third-party applications.
Innovation Solution
An authentication server authenticates users and sends application information to the image processing device, which then determines access requests based on stored application information, allowing only authorized applications to access and execute jobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image processing device allows access from all external applications, then the ease of operation is improved, but the security is compromised
Solution Approach 1:
The patent introduces an authentication server as an intermediary between external applications and the image processing device. The authentication server verifies application credentials and manages access permissions, allowing the image processing device to maintain security while enabling access from multiple third-party applications without pre-registering each application's information locally.
2Reliability
If the image processing device pre-registers information for all applications, then the security is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the application registration and authentication management function from the image processing device and relocates it to an external authentication server. This allows the image processing device to maintain security through verification without bearing the complexity of managing registration information for numerous applications locally.
Solution Approach 2:
The authentication server provides a universal authentication mechanism that serves multiple applications from different vendors. Instead of the image processing device needing to register each application individually, the authentication server handles multiple applications through a common authentication process, reducing overall system complexity.
3Adaptability or versatility
If the image processing device allows access from third-party applications, then the adaptability is improved, but the security control becomes difficult
Solution Approach 1:
The authentication server acts as a mediator that enables the image processing device to work with multiple third-party applications without directly managing their registration. The authentication server handles the complexity of verifying diverse applications from different vendors, allowing the image processing device to maintain adaptability while keeping security control simplified.

AI summary
An information processing device that performs an authentication to authenticate a user and controls operations of an image processing device based on a result of the authentication, comprising: an application that accesses the image processing device and performs a process to enable the image processing device to operate; and an authentication server that performs the authentication to authenticate the user and sends application information relating to the application to the image processing device when successfully authenticating the user through the authentication. The application generates an access request including information relating to the application and sends the generated access request to the image processing device when accessing the image processing device in response to an instruction given by the authenticated user who is successfully authenticated through the authentication.
