Confidential Text Readability Diagnosis via Reversible Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in effectively handling confidential words/phrases in text data, as they often require external diagnosis servers for readability checks, which can alter the text in ways that compromise confidentiality and readability diagnostics.
Innovation Solution
An information processing apparatus with a diagnosis request function that uses a substitute rule base to replace confidential words/phrases with alternative ones, ensuring that the replacements do not alter the text's readability and can be reversed after diagnosis, maintaining confidentiality and readability diagnostics integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If confidential words/phrases are replaced with alternative ones for readability diagnosis, then readability diagnostics can be performed, but the original confidential information is exposed or altered
Solution Approach 1:
The system performs preliminary replacement of confidential words/phrases with alternative ones before conducting readability diagnosis. This allows the diagnosis to be performed on modified text while the original confidential information remains protected in the unmodified text, resolving the contradiction between enabling diagnostics and protecting confidentiality.
Solution Approach 2:
The system introduces alternative words/phrases as intermediaries that temporarily replace confidential information during the diagnosis process. These intermediaries allow readability analysis to proceed without exposing actual confidential content, and the replacement can be reversed after diagnosis to restore the original text.
2Measurement precision
If external diagnosis servers are used for readability checks, then readability diagnostics can be performed, but text confidentiality is compromised
Solution Approach 1:
The system segments the text processing into two distinct parts: confidential text that remains unchanged and alternative text used for diagnosis. This segmentation allows external servers to process only the alternative versions while the original confidential text never leaves the local system, eliminating the confidentiality risk.
Solution Approach 2:
The system creates copies of the text with confidential words/phrases replaced by alternatives. These copied versions are then sent to external diagnosis servers for readability analysis, while the original confidential text remains securely stored locally and is never transmitted externally.
3Loss of information
If confidential words/phrases are replaced to protect confidentiality, then confidentiality is maintained, but readability diagnostics cannot be accurately performed
Solution Approach 1:
The system changes the parameter of word substitution by using alternative words/phrases that maintain the structural and grammatical properties of the original confidential words. This allows readability diagnostics to be performed on the modified text with accurate results that can be applied to the original text structure.

AI summary
An information processing apparatus includes a first replacing unit, an obtaining unit, and a second replacing unit. The first replacing unit replaces, in first document data including plural character strings, a first character string which satisfies a predetermined condition by a second character string including a character string which is not included in the first document data so as to generate second document data. The obtaining unit obtains a processing result generated by processing the second document data. The second replacing unit replaces the second character string included in the processing result by a character string corresponding to the first character string.
