Conference Event Package User Information Flagging

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In multimedia conferencing, anonymous participants cannot distinguish their own SIP URI from others, making it difficult to receive and differentiate private messages within a conference.

Innovation Solution

An extension is added to the conference event package with a new attribute, such as a 'yourown' flag, to explicitly indicate a user's own information within the XML document, allowing users to identify their own URI among others.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If anonymization function is used to protect user privacy, then user privacy is improved, but user ability to identify own information is worsened

Engineering Contradiction:

Improveuser privacyVSAvoiduser self-identification

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary mechanism (special flag or marker) that mediates between the anonymization requirement and self-identification need. The flag acts as a mediator that allows the system to maintain anonymity while providing a way for users to identify their own information without revealing identity to others.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the information structure by adding a distinct flag attribute to user information elements. This segmentation separates the identification function (flag) from the anonymized content (SIP URI), allowing the system to provide self-identification without compromising privacy.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple anonymous participants join conference, then conference participation is improved, but participant distinguishability is worsened

Engineering Contradiction:

Improveconference participationVSAvoidparticipant distinguishability

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies local quality by adding a unique identifying flag specifically to each participant's information element. This allows each anonymous participant to have a distinctive local marker that enables differentiation without revealing global identity information to other participants.

Inventive Principle:

Principle #3Local quality

3Loss of information

If conference event package provides complete participant information, then information completeness is improved, but privacy protection is worsened

Engineering Contradiction:

Improveinformation completenessVSAvoidprivacy protection

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent extracts the identification function from the SIP URI itself and places it in a separate flag attribute. This extraction allows the system to provide complete information (including SIP URI) while protecting privacy, because the identification capability has been separated from the identifying data.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A system and method for indicating user information in a conference event package. An extension is added to the current conference event package in various embodiments of the present invention. This extension adds a new attribute to user information, including an indicator that explicitly indicates to a user that certain information is the user's own information. Therefore, when a user desiring anonymity joins a conference and then subscribes to the conference event package in order to obtain the roster, the conference lists one of the participants with an indicator that indicates to the user that this particular participant is the user.
