Management Server Temporary ID Link Conversion

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems that use unique or temporary IDs for users face issues with privacy as real IDs can be disclosed, leading to unwanted contacts, and temporary IDs are not suitable for one-on-one communications.

Innovation Solution

A management server with memory sections that store temporary ID links associating real and temporary IDs, converting messages to prevent disclosure of real IDs and allowing secure, anonymous communication by converting temporary IDs based on stored links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a unique ID is set for each user to enable permanent communication, then communication reliability is improved, but user privacy is worsened because the real ID can be disclosed to others

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidprivacy disclosure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a temporary ID as an intermediary between the user's real ID and communication partners. The temporary ID serves as a mediator that allows communication to occur without directly exposing the real ID, thus resolving the contradiction between communication reliability and privacy protection

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the identification system into two distinct parts: a real ID for system identification and a temporary ID for communication. This segmentation allows the real ID to remain protected while the temporary ID handles communication functions, resolving the privacy disclosure issue

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If a temporary ID is used for anonymous communication, then user privacy is improved, but one-on-one communication capability is worsened because temporary IDs are not suitable for individual correspondence

Engineering Contradiction:

Improveprivacy protectionVSAvoidone-on-one communication capability

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent performs preliminary actions by pre-establishing binding relationships between real IDs and temporary IDs in the server before communication occurs. This allows the system to resolve temporary IDs to real IDs when needed for one-on-one communication, while maintaining anonymity during the communication process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The server acts as an intermediary that manages the mapping between temporary IDs and real IDs. It receives messages with temporary IDs, resolves them to real IDs using pre-established bindings, and delivers messages appropriately, enabling one-on-one communication while preserving privacy

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the correspondence relationship between real ID and temporary ID is disclosed, then communication efficiency is improved by enabling direct addressing, but user privacy is worsened by leaking personally identifiable information

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidinformation leakage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The server serves as an intermediary that knows the correspondence relationship between real IDs and temporary IDs but does not disclose this information to communication partners. The server uses this knowledge internally to route messages efficiently while preventing information leakage to external parties

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the ID correspondence management function from the communication endpoints and centralizes it in the server. The server extracts and maintains the binding information internally without exposing it to users, enabling efficient routing while protecting privacy

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A management server comprises a memory section including at least two memory areas, a message reception section which receives a message, a message conversion section which converts the message and generates a transmission message and a message transmission section which transmits the transmission message to a specified destination, wherein the memory section stores in the memory areas a temporary Identification (ID) link in which a real ID of a user and a temporary ID of the user are associated, and wherein the message conversion section converts, in a case where the message includes a first temporary ID which corresponds to a real ID and is stored in a first memory area, the first temporary ID to a second temporary ID which corresponds to the real ID, on a basis of the temporary ID link stored in a second memory area, and generates the transmission message.
