Image Processing Authentication with Dynamic Security Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses face inefficiencies in user authentication, requiring time-consuming strict authentication for applications that do not need security, and simple authentication for administrators, which compromises security.
Innovation Solution
Implementing a dual authentication process where a first authentication provides basic access and a second, more secure authentication is triggered based on user authority, ensuring appropriate security and usability by differentiating authentication methods based on user roles and application characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strict user authentication is used for applications requiring security, then security is ensured, but time-consuming operations are required which reduces usability
Solution Approach 1:
The patent changes the authentication parameter (security level) based on user authority and application characteristics. Administrators use strict authentication for security-critical operations, while general users experience simplified authentication for non-critical applications. This dynamic parameter adjustment resolves the contradiction by adapting security strength to actual needs.
Solution Approach 2:
Different authentication methods are applied to different user groups and application contexts. Instead of uniform strict authentication, the system applies localized authentication quality: strict authentication for administrators accessing security-sensitive functions, and simple authentication for general users accessing standard applications. This resolves the contradiction by making authentication quality match local requirements.
2Ease of operation
If simple authentication is used for administrators, then usability is improved, but security is compromised
Solution Approach 1:
The system dynamically changes authentication parameters based on user role and application context. When an administrator accesses applications requiring security, strict authentication is enforced. For routine applications, simplified authentication is permitted. This resolves the contradiction by adjusting security parameters to match actual operational needs.
Solution Approach 2:
The authentication method is made dynamic rather than static. The system adapts authentication strength based on real-time conditions including user authority level and application security requirements. This dynamic approach resolves the contradiction by allowing administrators to experience both simple and strict authentication depending on context, optimizing both usability and security.
3Reliability
If strict authentication is applied to all users for all applications, then security is maximized, but authentication burden increases for applications that do not require security
Solution Approach 1:
The patent applies different authentication qualities to different user-application combinations. General users accessing non-security applications experience simple authentication, while administrators accessing security-critical applications experience strict authentication. This localized quality approach resolves the contradiction by eliminating unnecessary authentication complexity for low-risk scenarios while maintaining high security where needed.
Solution Approach 2:
The authentication system is segmented into multiple levels and paths. Instead of a single uniform authentication process, the system creates segmented authentication flows: one path for administrators with strict authentication, another for general users with simple authentication, and conditional paths based on application security requirements. This segmentation resolves the contradiction by allowing users to follow the appropriate authentication path based on their needs.

AI summary
An image processing apparatus using an authentication technique that enables user authentication suited to application characteristics and user authorities, thus ensuring security and enhancing usability at the same time. An authority of a user authenticated in a first authentication process for authenticating the user is obtained. When the obtained authority of the user is a predetermined authority, control is provided to give the predetermined authority to the user authenticated in the first authentication process. When the authority of the user is not the predetermined authority, control is provided to authenticate the user in a second authentication process for authenticating the user more securely than in the first authentication process, and when the second authentication process is successful, give the obtained authority to the user.
