Solution Overview

Problem

Users often cannot recall parts of conversations recorded on mobile devices and may infringe on others' privacy when attempting to record multiparty conversations, as existing solutions require advance recording and lack efficient methods for recreating conversations from individual recordings.

Innovation Solution

A system and method for selectively generating a multiparty conversation from individually recorded communications by recording each participant's portion, transmitting them to a network device, and reconstructing the conversation based on user requests, while ensuring privacy through trust groups and filtering out non-consenting participants' voices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a user records a multiparty conversation using a mobile device, then the user can review the conversation, but the user may infringe on other people's privacy rights

Engineering Contradiction:

Improveconversation recallVSAvoidprivacy infringement

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent segments the multiparty conversation into individual communication recordings, one from each participant's mobile device. Each recording captures only that participant's perspective, and these segmented recordings are then selectively combined to reconstruct the full conversation, allowing privacy control at the individual level.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by allowing different participants to have different privacy settings for their individual recordings. Each participant can control whether their recording is included in the reconstructed conversation, enabling selective privacy protection for different portions of the overall conversation based on individual preferences.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If a user attempts to record a conversation without advance preparation, then the user can capture the conversation, but the user cannot recall parts of it later

Engineering Contradiction:

Improveconversation recordingVSAvoidconversation recall

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent implements preliminary action by automatically recording communications in the background before the user needs to review them. The system pre-captures individual communications from each participant and stores them, so when a user wants to review a conversation, the recordings are already available and can be quickly reconstructed without needing to have anticipated the review need in advance.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If individual communications from multiple participants are combined to reconstruct a conversation, then the conversation can be fully captured, but the system complexity increases

Engineering Contradiction:

Improveconversation completenessVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary that handles the complex tasks of receiving, storing, and combining individual communication recordings from multiple participants. The server mediates between the participants' mobile devices and the users who want to review conversations, managing the reconstruction process and privacy settings without requiring complex logic in the user's mobile device.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Loss of information

If all participants' recordings are included in the reconstructed conversation, then the conversation is complete, but non-consenting participants' privacy is violated

Engineering Contradiction:

Improveconversation completenessVSAvoidprivacy consent

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making the conversation reconstruction process adaptive to individual privacy preferences. The system dynamically determines which participant recordings to include based on each participant's consent settings, rather than using a fixed rule of including all recordings or excluding any based on predetermined criteria.

Inventive Principle:

Principle #15Dynamics

AI summary

In one embodiment, a method includes recording a communication at a mobile device, wherein the recorded communication is a user's portion of a conversation between the user and at least one other participant, transmitting the recorded communication to a network device, transmitting a request for the conversation to the network device, and receiving the conversation generated from the recorded communication and at least one other recorded communication from the other participant. An apparatus is also disclosed.
