Authentication System for Secure Image Processing Job Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image processing systems, there is a risk of unauthorized use of printing devices for business purposes when personal accounts are used, leading to potential printing of private data, as existing authentication methods do not adequately manage job execution and data access.
Innovation Solution
The system transmits identification information to an image processing apparatus, acquires account information, logs in to a server, and associates this information with job requests to ensure that only authorized data is processed, preventing unauthorized use by managing account information and identification within the device and server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user uses a single account for both private and business purposes, then the ease of operation is improved, but the reliability of authentication and security of data access deteriorates
Solution Approach 1:
The patent segments authentication by introducing device-specific identification information that distinguishes between business and private devices. The system divides the authentication process into device identification and user account verification, allowing the same user account to be used on different devices with appropriate access controls.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where the image processing apparatus verifies both device identification information and user account credentials before granting access. This intermediary layer prevents direct unauthorized access while maintaining ease of use for authorized users.
2Reliability
If authentication is required for job execution, then the security and reliability are improved, but the ease of operation and device complexity increase
Solution Approach 1:
The patent implements preliminary authentication by requiring device identification information to be registered with the image processing apparatus before use. This preliminary action establishes trust relationships in advance, allowing faster authentication during actual job execution without requiring repeated complex verification.
Solution Approach 2:
The system enables self-service authentication where the image processing apparatus automatically verifies device identification and user credentials without requiring manual intervention from administrators. The apparatus autonomously manages authentication states and grants or denies access based on verified credentials.
3Reliability
If device-specific authentication is implemented, then the reliability of job execution control is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal authentication framework where the image processing apparatus handles multiple authentication types (device identification, user credentials, account verification) through a single integrated system. This multi-functional approach manages complexity centrally rather than requiring separate mechanisms for each authentication layer.
Solution Approach 2:
The system uses feedback mechanisms where the image processing apparatus communicates authentication results back to the information processing device, and verifies device identification information in real-time. This feedback loop ensures reliable job execution control by continuously verifying authentication states without requiring complex manual monitoring.
Data Source
AI summary
A non-transitory storage medium stores instructions which, when executed by a processor of an information processing device, cause the processor to: transmit, to an image processing apparatus, identification information for identifying a login requestor; acquire account information transmitted from the image processing apparatus when the identification information is registered in the image processing apparatus; cause the information processing device to log in to a server using the account information; and perform at least one of: acquiring image data from the server and transmitting the image data and the identification information to the image processing apparatus; and transmitting an image reading request and the identification information to the image processing apparatus, acquiring image data from the image processing apparatus, and transmitting the image data acquired from the image processing apparatus, to the server.
