Authentication Registration for Seamless Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a processing system where an image formation apparatus and a personal computer are interconnected, users who have already been authenticated by the image formation apparatus need to undergo additional authentication when using the personal computer's functions, which is inconvenient and unnecessary.
Innovation Solution
The system implements a registration mechanism where the image formation apparatus registers identification information of connected devices, allowing the personal computer to execute requests without re-authenticating users who have already been authenticated by the image formation apparatus, using a device information registration table and individual setting information table to manage user permissions and settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the personal computer requires additional authentication for users who have already been authenticated by the image formation apparatus, then security control is maintained, but user convenience and access efficiency deteriorate
Solution Approach 1:
The image formation apparatus performs preliminary authentication of the user and stores the authentication result. When the personal computer receives a request from the image formation apparatus, it checks the pre-stored authentication information to determine whether to grant access, thereby avoiding the need for users to undergo authentication again on the personal computer.
Solution Approach 2:
The image formation apparatus acts as an intermediary authentication server between the user and the personal computer. It authenticates the user first and then communicates the authentication result to the personal computer, which uses this information to make access decisions, thus eliminating redundant authentication steps.
2Reliability
If the personal computer requires additional authentication for users authenticated by the image formation apparatus, then access security is ensured, but processing time and system complexity increase
Solution Approach 1:
Authentication is performed in advance by the image formation apparatus before the personal computer needs to access resources. The authentication result is stored and reused when the personal computer receives requests, eliminating the need for repeated authentication processes and reducing processing time.
Solution Approach 2:
The image formation apparatus provides feedback about the user's authentication status to the personal computer. The personal computer uses this feedback information to determine whether to allow access without performing additional authentication, thereby reducing processing time while maintaining security.
3Reliability
If the system implements authentication checks on the personal computer for users authenticated by the image formation apparatus, then security control is maintained, but system complexity and operational steps increase
Solution Approach 1:
The authentication functions of the image formation apparatus and the personal computer are merged into a unified authentication system. The image formation apparatus serves as the primary authentication authority, and the personal computer relies on its authentication decisions, thereby reducing overall system complexity while maintaining security control.
Solution Approach 2:
The image formation apparatus is given a universal authentication function that serves both its own access control and the access control of the personal computer. This multi-functionality eliminates the need for separate authentication systems in both devices, reducing system complexity.

AI summary
A processing apparatus includes a processing unit and a first registration unit. The processing unit executes a requested process. The first registration unit registers therein first identification information which identifies another device, in advance. If a request for the process is received from said another device, the processing unit complies with the request without authenticating a user who makes the request on condition that the first identification information of said another device which makes the request is registered in the first registration unit.
