Text Summarization Security via Sensitive Word Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for summarizing text information often expose confidential data when transmitting it to external servers, posing a risk to sensitive information.
Innovation Solution
An electronic apparatus and method that identifies the security level of text information and converts sensitive words before summarization, either locally or through a server, to protect personal and confidential data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If text information is transmitted to an external server for summarization, then summarization capability is improved, but confidential information exposure risk increases
Solution Approach 1:
The system performs preliminary identification and conversion of confidential words in the text information before transmitting it to the external server. By pre-processing the text to mask or replace sensitive words, the system enables the server to perform summarization on the converted text without exposing confidential information, thus resolving the contradiction between summarization capability and information security.
Solution Approach 2:
The system introduces an intermediary conversion process that acts as a mediator between the original text information and the external server. The confidential words are converted into placeholder text or anonymized forms before server transmission, allowing the server to process the text for summarization while the intermediary layer protects the underlying confidential information from exposure.
2Reliability
If confidential words are converted before summarization, then information security is improved, but processing complexity increases
Solution Approach 1:
The system segments the text processing task into distinct stages: first identifying confidential words using predefined patterns or lists, then converting them to placeholder text, and finally transmitting to the server for summarization. This segmentation of the processing workflow makes the complex security measures more manageable and systematically implementable without overwhelming the overall system.
Solution Approach 2:
The system changes the parameter of word representation by converting confidential words into placeholder text or anonymized forms. This parameter transformation maintains the structural integrity of the text for summarization purposes while fundamentally altering the sensitive information content, thereby achieving security enhancement through a relatively simple substitution operation.

AI summary
An electronic apparatus and a controlling method thereof are provided. The method of controlling an electronic apparatus according to an embodiment includes: obtaining first text information including a plurality of words, identifying a security level of the first text information based on at least one of a source from which the first text information is obtained or a type of the first text information, obtaining second text information by converting at least one of the plurality of words included in the first text information based on the identified security level, and obtaining first summary sentence information summarizing the second text information through a summary module.
