Relaying Server Personal Information Extraction for Cloud Query Privacy

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems fail to effectively protect personal information from being transmitted, stored, or managed by cloud service servers, especially when users input free queries or troubleshooting requests, leading to potential information leakage and management issues.

Innovation Solution

A system comprising a client terminal, a relaying and processing server, and a cloud service server that extracts and processes personal information from user queries, encoding or substituting it to prevent recognition, ensuring that only processed query content is transmitted to the cloud service server, thereby maintaining user privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If query content is transmitted directly to cloud service server for processing, then query processing service quality is improved, but personal information security deteriorates

Engineering Contradiction:

Improvequery processing service qualityVSAvoidpersonal information exposure

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts personal information from query content using a personal information extraction module before transmission to the cloud service server. This separation removes the harmful element (personal information) from the data stream while preserving the useful content for query processing, thereby resolving the contradiction between service quality and information security.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a relaying server as an intermediary between the user terminal and cloud service server. This mediator performs personal information processing and filtering, allowing query content to be transmitted for processing while preventing direct exposure of personal information to the cloud server, thus maintaining both service quality and security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If personal information is processed and encoded before transmission, then personal information security is improved, but query processing efficiency deteriorates

Engineering Contradiction:

Improvepersonal information protectionVSAvoidquery processing efficiency

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent performs personal information extraction and processing in advance before query content is transmitted to the cloud service server. By preparing the data beforehand (removing or encoding personal information), the system avoids additional processing delays during query execution, thus maintaining efficiency while improving security.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If personal information extraction and processing is performed, then personal information security is improved, but system complexity increases

Engineering Contradiction:

Improvepersonal information protectionVSAvoidsystem structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If free query input is allowed without form constraints, then user convenience is improved, but personal information leakage risk increases

Engineering Contradiction:

Improveuser convenienceVSAvoidpersonal information leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent enables the system to automatically identify and process personal information within free-form query input without requiring users to follow specific formats or manually redact information. The personal information extraction module autonomously detects and handles sensitive data, maintaining user convenience while preventing information leakage.

Inventive Principle:

Principle #25Self-service

AI summary

The present invention relates to a system for providing a query processing service and, particularly, to a system for providing a query processing service on the basis of personal information protection, which is configured to, when a service provider intends to process a query content for solving a problem provided by a user through a public service or a cloud service, process personal information required for protection as information that cannot be recognized, rather than transmit the query content to the cloud service server as it is, and then transmit the processed query content including the personal information required for protection, such that it is possible to prevent the personal information required for protection from being transmitted to, stored in, and managed by the cloud service server regardless of whether a user recognizes such a situation.
