Task Authentication Management for Collaborative Document Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In collaborative tasks using interactive whiteboards or similar devices, users face inefficiencies due to the need to repeatedly input authentication information to access different electronic documents, even after initial access, and may be restricted from accessing documents post-task if they lack permission.
Innovation Solution
A management device with an electronic data access unit, management unit, and receiver that manages task information associating user authentication with access destinations, allowing seamless access to electronic data by acquiring and storing authentication information for subsequent access without user input, enabling flexible access control and permission management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system prompts users to input authentication information for each document access, then security is maintained, but user convenience and access efficiency deteriorate
Solution Approach 1:
The system performs preliminary authentication by storing authentication information for each user-document pair before actual access is needed. When a user wants to access a document, the system checks if authentication information is already stored, eliminating the need for repeated authentication inputs while maintaining security.
Solution Approach 2:
The system creates a copy of authentication information in the form of authentication tickets or tokens that are stored and reused. Instead of requiring users to re-enter credentials, the system uses these stored authentication copies to verify access rights, improving convenience while preserving security through the original authentication verification.
2Reliability
If different access permissions are set for each document, then security and document control are improved, but access efficiency and task execution speed deteriorate
Solution Approach 1:
The system merges multiple authentication checks into a single unified authentication process. By combining authentication information for multiple documents into a single set of stored credentials, the system allows users to access multiple documents without repeated authentication, thereby improving task execution efficiency while maintaining individual document permission controls.
Solution Approach 2:
The authentication system is designed to be universal, where a single authentication process serves multiple documents. The stored authentication information can be reused across different documents that a user has permission to access, making the authentication mechanism multi-functional and improving overall productivity without sacrificing document-specific access control.
3Reliability
If users can only access documents they have permission for, then security is maintained, but collaboration flexibility and post-task access capability deteriorate
Solution Approach 1:
The system introduces an intermediary authentication management mechanism that mediates between strict permission control and collaboration flexibility. The authentication information storage system acts as an intermediary layer that automatically provides access to users based on their permission levels, enabling seamless collaboration and post-task document access without compromising security through manual authentication prompts.
Data Source
AI summary
A management device manages information of a task having been executed by users cooperatively. An electronic data access unit accesses electronic data by using authentication information of a corresponding user. A management unit manages, for each task, task information in which pieces of authentication information of the users having participated in the task are associated with access destination information. A receiver receives a request, from a user, for access to the electronic data. When the electronic data access unit needs the authentication information of a user different from the requester user having participated in the task same as the task in which the requester user has participated to access the electric data as a target of the request, the electronic data access unit acquires the authentication information of the different user based on the task information and accesses the electronic data using the acquired authentication information of the different user.
