Hyperlink Accessibility Determination via Pre-authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques face difficulties in determining the accessibility of a hyperlinked file's link destination, especially when the returned object content changes with each access, making it challenging to identify whether the acquired object is a correct response or a result of denied access, and managing access restriction information becomes complicated with changes in access destination specifications.
Innovation Solution
A method that extracts hyperlinks from target files, performs authentication operations, compares objects acquired through these operations, and presents information on accessibility based on these comparisons, using a system comprising a link extracting unit, authentication screen retrieving unit, and accessibility determining unit, with an authentication information database to manage access permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If authentication operations are performed to determine link accessibility, then the accuracy of accessibility determination is improved, but the system complexity increases
Solution Approach 1:
The system performs authentication operations in advance before displaying hyperlinked files to pre-determine accessibility status. By conducting authentication beforehand and storing the results, the system avoids complex real-time authentication checks during file display, thus improving determination accuracy while managing system complexity through preliminary processing.
Solution Approach 2:
The system creates and stores copies of authentication results and accessibility determination data in a database. Instead of performing complex authentication operations repeatedly, the system retrieves pre-stored authentication copies, thereby maintaining high determination accuracy while significantly reducing the computational complexity and processing overhead.
2Productivity
If authentication information is stored and managed, then the efficiency of accessibility checking is improved, but the management complexity of access restrictions increases
Solution Approach 1:
The system automatically performs authentication operations and stores accessibility determination results without requiring manual intervention. The database automatically updates with authentication outcomes, and the system self-manages the authentication information lifecycle, thereby improving checking efficiency while minimizing the operational complexity of managing access restrictions.
Solution Approach 2:
The system implements a feedback mechanism where authentication results are automatically captured, stored in the database, and used to update accessibility information. This automated feedback loop ensures that the system continuously maintains accurate accessibility data without manual management, improving efficiency while reducing the complexity of access restriction management through automation.
3Reliability
If multiple authentication operations are performed, then the reliability of accessibility determination is improved, but the processing time increases
Solution Approach 1:
The system performs multiple authentication operations in advance during system initialization or when accessibility information is cached. By completing multiple authentication checks beforehand and storing the results, the system ensures high reliability of accessibility determination while avoiding the time penalty of performing multiple authentication operations during each file display or link check event.
Solution Approach 2:
The system stores copies of authentication results from multiple authentication operations in a database. When accessibility needs to be determined, the system retrieves pre-computed authentication copies rather than re-executing multiple authentication operations, thereby maintaining high determination reliability through multiple authentication checks while significantly reducing the processing time required for each accessibility check.
Data Source
AI summary
The accessibility of a hyperlinked files is displayed. A hyperlink that references a resource is extracted from a target file. An attempt to acquire the resource is made by performing a first authentication operation. A first object is received in response to performing the authentication operation. A second object is acquired by performing a second authentication operation using pre-determined authentication information. The first object and the second object are compared to determine if the first object is the same as the second object. Information indicating the accessibility of the resource is presented via a display apparatus.
