Answer Generation Access Mediation for Restricted File Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems restrict answer generation based on user access rights, limiting flexibility and preventing users from obtaining desired answers.
Innovation Solution
An information processing system that controls the use of file data independently of user access rights to generate and present answer data, allowing access and manipulation by a secondary user or system, and enabling regeneration and abstraction level changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control is strictly enforced based on user access rights to file data, then security and access control are improved, but flexibility in answer generation deteriorates
Solution Approach 1:
The patent segments the answer generation process into multiple stages: file data acquisition stage (where access control is relaxed or bypassed) and answer presentation stage (where access control is enforced). This allows the system to acquire necessary file data without strict access restrictions while still protecting sensitive information in the final answer presentation.
Solution Approach 2:
The system introduces an intermediary mechanism (the answer generation system itself) that mediates between the file data storage and the user. This intermediary can access file data regardless of user access rights for the purpose of generating answers, while still ensuring that the final answer respects access control requirements when presenting information to users.
2Reliability
If file data access is restricted according to user access rights, then security is improved, but answer quality and completeness deteriorate
Solution Approach 1:
The system separates the data acquisition function from the data presentation function. During acquisition, the system can access any file data relevant to the question regardless of user access rights. During presentation, it applies access control to ensure security. This segmentation allows complete answer generation while maintaining security.
Solution Approach 2:
Instead of restricting file data access at the source and filtering answers later, the patent inverts the approach: it allows full access to file data for answer generation purposes, then applies access control only when presenting the generated answer to the user. This inversion ensures answer completeness while maintaining security.
3Reliability
If access control is enforced on file data used for answer generation, then access control compliance is improved, but system complexity increases
Solution Approach 1:
The patent extracts the access control requirement from the file data acquisition process and applies it only to the answer presentation process. This extraction simplifies the overall system by removing access control checks from the data retrieval stage, reducing complexity while maintaining compliance through controlled output.

AI summary
An information processing system includes a processor configured to: receive question data input from a user; in generation of answer data to the question data using file data to which it is preset whether or not the user has an access right, in a case where access to the file data is restricted or prohibited by the access right of the user, control the use of the file data in the generation of the answer data independently of control of the access right to generate the answer data; and present the answer data to the user.
