Information Processing Device Restriction Removal Condition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing devices fail to ensure adequate authentication for electronic documents, allowing unauthorized access even after approval, as approved documents can be viewed without restrictions.
Innovation Solution
An information processing device with a processor that receives display requests for electronically restricted documents, requires approval, and sets restriction removal conditions based on intended use, ensuring authentication through pre-determined methods such as one-time passwords or registration keywords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If approved electronic documents can be viewed without restrictions after approval, then ease of operation is improved, but security and authentication are worsened
Solution Approach 1:
The system performs preliminary authentication actions before document display by requiring users to satisfy predetermined restriction removal conditions (such as entering one-time passwords or registration keywords) before the document becomes accessible. This preliminary security check ensures that even though documents can be viewed easily after approval, proper authentication occurs in advance.
Solution Approach 2:
The system introduces an intermediary authentication mechanism between the approved document and the user. Instead of direct access, users must pass through an authentication gate where they provide verification information (one-time passwords, registration keywords) that mediates between their identity and document access rights.
2Productivity
If display restrictions are removed after approval, then productivity is improved, but unauthorized access risk increases
Solution Approach 1:
The system executes preliminary authentication actions requiring users to satisfy restriction removal conditions (entering one-time passwords, registration keywords, or other verification information) before document access is granted. This preliminary security measure ensures efficient document access for authorized users while preventing unauthorized access.
Solution Approach 2:
The system dynamically changes access parameters based on authentication status. Documents transition from a restricted state (where access requires verification) to an accessible state (where no additional restrictions apply) only after the user successfully meets the predetermined conditions, thereby controlling disclosure ranges effectively.
3Reliability
If authentication requirements are added for approved documents, then security is improved, but device complexity increases
Solution Approach 1:
The information processing device performs preliminary authentication by checking whether predetermined restriction removal conditions are satisfied before displaying approved documents. The conditions include entering one-time passwords, registration keywords, or other verification information, ensuring security without requiring complex continuous authentication mechanisms.
Solution Approach 2:
The system employs disposable authentication mechanisms such as one-time passwords that are valid for single use only. This approach provides strong security without requiring complex long-term authentication infrastructure, as each authentication credential is used once and then discarded.

AI summary
An information processing device (1) including a processor (11) that functions as: a receiving section which receives, from a first user terminal, a display request of an electronic document on which a display restriction is imposed, the display request being accompanied by an intended use of the electronic document; an approval section which receives approval of the display request that is received by the receiving section; and a setting section which sets a restriction removal condition that is determined in advance in association with the intended use accompanying the display request when the approval section receives the approval of the display request.
