Local Authentication Account Self-Creation During Network Disruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems for devices like printing devices face inefficiencies when network connectivity issues or server malfunctions prevent users from accessing device features, even if the local machine is functioning properly.
Innovation Solution
The system allows users to self-create and self-administer local accounts on devices after initial authentication by an external server, enabling local authorization without relying on network connectivity. This involves receiving user identification information, obtaining additional elements through a card reader, and synchronizing local accounts with external authentication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network authentication through external server is used, then authentication efficiency and centralized management are improved, but system reliability deteriorates when network connectivity is lost
Solution Approach 1:
The system performs preliminary actions by creating local authentication accounts in advance on the printing device before network connectivity is lost. These local accounts are synchronized with the external authentication server when the network is available, enabling the device to authenticate users locally when the server becomes unreachable, thus resolving the contradiction between centralized authentication efficiency and system reliability during network disruptions.
2Ease of operation
If local accounts are allowed to be self-established, then ease of operation is improved, but security control deteriorates due to potential incorrect information
Solution Approach 1:
The system enables self-service by allowing users to automatically create and manage their own local authentication accounts on the printing device without requiring system administrator intervention. The synchronization mechanism with the external authentication server ensures that self-created accounts are validated and secured, thus maintaining both ease of operation and authentication security simultaneously.
3Stability of the object's composition
If local accounts are synchronized with external server, then data consistency is improved, but network dependency worsens
Solution Approach 1:
The system performs preliminary synchronization of authentication data to local accounts before network disruptions occur. This preliminary action ensures that authentication data consistency is maintained in local accounts, allowing the device to operate independently without continuous network dependency while preserving data integrity through pre-synchronized information.
Data Source
AI summary
User identification information is received through a user interface device. A processor device supplies the user identification information through an input/output device to an external computerized device to receive, in response, external authorization to use features of an apparatus. The user interface device outputs a menu having options to create a local account based on the external authorization and, in response, receives instructions to create a local account using the processor device. The local account is created based on the instructions being received using the processor device. The local account is stored in a memory device. After creation of the local account, the processor device generates local authorization to use the features of the apparatus based on the user identification information matching information in the local account stored in the memory device, without contacting the external computerized device for the external authorization.
