Facsimile Log Page Hyperlink Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems for facsimile communications do not adequately restrict access to confidential image data, allowing unauthorized users to view sensitive information through hyperlinks on web pages displaying communication details.
Innovation Solution
A communication system with an image storing unit, page generating unit, and access determining unit that generates web pages with hyperlinks only to image data for which access is allowed, based on the contents of the communication details, ensuring that confidential content is not accessible to unauthorized users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a web page displaying communication details with hyperlinks to image data is generated and distributed via network, then users can conveniently browse communication details and access image data remotely, but unauthorized users can also access confidential image data through the same web page
Solution Approach 1:
The patent segments the web page into two distinct versions: a public web page displaying only communication details without hyperlinks to image data, and a private web page displaying both communication details and hyperlinks to image data. This segmentation allows the system to provide convenient browsing for authorized users while preventing unauthorized access to confidential image data by restricting the private web page to authenticated users only.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism between the web page and the image data. The access determining unit acts as a mediator that checks user authentication status before allowing access to the private web page with hyperlinks to image data. This intermediary layer prevents unauthorized users from accessing confidential image data while maintaining convenient browsing for authenticated users.
2Loss of information
If all image data is made accessible through hyperlinks on the web page, then complete information transparency is achieved, but security and confidentiality of sensitive information is compromised
Solution Approach 1:
The patent applies local quality by providing different levels of access to different parts of the information. The public web page provides full transparency for communication details, while the private web page provides selective transparency for image data based on user authentication status. This allows complete information transparency for authorized users while maintaining security and confidentiality for unauthorized users.
Solution Approach 2:
The patent introduces dynamic accessibility where the web page content and hyperlink availability change based on user authentication status. The access determining unit dynamically adjusts which web pages are accessible and which hyperlinks are active, allowing the system to transition between high transparency mode for authenticated users and restricted access mode for unauthorized users, thus balancing information transparency with security.
Data Source
AI summary
When log data is stored in a shared area of RAM provided in a multifunction device, a personal computer generates and transmits a log page having links to image data. These links are links to files (image data) registered in a log table. The log table includes a list of content identified by the log data stored in the RAM of the multifunction device. This log data can identify a file only when the multifunction device determines that the image data may be recorded. Accordingly, the personal computer can generate log pages having links to files for which image data can be recorded, that is, files that can be made public via a communication network.
