Authentication Ticket Management for Image Processing Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems face high processing loads and security concerns when service providers perform communications, particularly due to the need for user authentication for every internal communication, which can lead to inefficiencies and security issues.
Innovation Solution
An image processing system that manages login and authentication for image forming apparatuses, issues authentication tickets, and includes a task management unit to store and process image requests, reducing the processing load and enhancing security by using a service providing system with a user management unit, task processing unit, and storage unit to handle image data processing requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is performed for every internal communication on the service provider side, then security is improved, but processing load increases significantly
Solution Approach 1:
The service provider performs user authentication in advance before the image forming apparatus communicates with it. The authentication result (authentication ticket) is stored and reused for subsequent internal communications, eliminating the need for repeated authentication processes and reducing processing load while maintaining security.
2Adaptability or versatility
If the service provider performs processing without limitation, then service flexibility is improved, but security control deteriorates
Solution Approach 1:
The service provider implements differentiated access control where different authentication tickets grant different levels of access rights. Instead of uniform processing for all requests, the system applies specific authorization rules based on the type of authentication ticket presented, allowing flexible service delivery while maintaining granular security control.
3Reliability
If authentication tickets are used for service access, then access control is improved, but communication efficiency deteriorates due to repeated authentication requirements
Solution Approach 1:
Authentication is performed once in advance by the service provider before the image forming apparatus initiates communication. The authentication ticket obtained is cached and automatically presented for subsequent internal communications, converting a repeated authentication process into a single preliminary action that improves communication efficiency while maintaining access control.

AI summary
Disclosed is an image processing system including a user management unit that manages login and issues an authentication ticket to an image forming apparatus; a task request unit that makes an image processing request with an addition of the authentication ticket; a detection unit that detects whether the image processing request is authorized; a task processing unit that makes the image processing request with an addition of user information accompanied by identification information; a task management unit that stores a task in a task queue and receives an inquiry about the task; one or more image processing units that acquire the processible image processing request to perform the image processing; a storage unit that stores image data processed by the one or more image processing units; and an acquisition unit that specifies a location where the processed image data are stored and acquires the image data.
