Solution Overview

Problem

As generative AI service providers collect users' conversational data, there is a risk of user privacy leaks, as they can analyze and extract sensitive information such as personalities, occupations, emotions, event opinions, and tendencies.

Innovation Solution

An intelligent service system using a proxy server that sends a session identifier and request content to an AI server without user identity information, and transmits request contents of different users through service session channels in a way that confuses the data, making it difficult for the AI server to analyze user profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the AI server directly receives user service requests, then the service processing efficiency is improved, but the user privacy security deteriorates

Engineering Contradiction:
Improveservice processing efficiencyVSAvoiduser privacy leakage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a proxy server as an intermediary between users and the AI server. The proxy server receives user service requests, removes identity information, and forwards only the service content to the AI server. This mediator structure enables the AI server to process services efficiently while preventing direct access to user identity data, thus resolving the contradiction between service efficiency and privacy security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the AI server receives complete user information including identity, then the service personalization is improved, but the privacy protection deteriorates

Engineering Contradiction:
Improveservice personalizationVSAvoidprivacy exposure
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes identity information from user service requests before forwarding them to the AI server. The proxy server separates identity data from service content, retaining only the necessary service requirements. This extraction approach allows the AI server to provide personalized services based on service content while preventing exposure of user identity information.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If user identity information is transmitted to the AI server, then the service accuracy is improved, but the privacy risk increases

Engineering Contradiction:
Improveservice accuracyVSAvoidprivacy risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The proxy server acts as an intermediary that processes user requests by removing identity information while preserving service content. This intermediary structure maintains service accuracy by transmitting complete service requirements to the AI server while preventing privacy risks by blocking identity information transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If conversational data is collected for model optimization, then the AI model performance is improved, but the user data security deteriorates

Engineering Contradiction:
Improvemodel optimization efficiencyVSAvoiddata security risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes identity information from conversational data before transmission to the AI server. The proxy server separates personally identifiable information from service content, allowing the AI server to collect and analyze conversational data for model optimization while preventing security risks by eliminating identity data from the collected information.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An intelligent service system includes: a proxy server, where the proxy server has a user session channel established between the proxy server and a user requesting a service, and assigns a session identifier to the user session channel; and the proxy server has one or more service session channel established between the proxy server and an external Al server; the proxy server is to receive a service request from the user through the session channel; and in the event that the user authentication passes, the session identifier corresponding to the user and the request content in the service request are sent to the Al server through any of the one or more service session channel.
