Solution Overview

Problem

Users face challenges in maintaining privacy and anonymity when communicating with third parties over networks, as their email addresses can be used to obtain personal information and receive unwanted marketing, compromising their identity.

Innovation Solution

A decentralized messaging system using a distributed ledger creates a messaging inbox with an alphanumeric address that does not include identifying information, allowing users to filter content based on preferences, ensuring privacy and blocking unwanted messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users provide their primary email address to communicate with third parties, then communication capability is improved, but privacy and anonymity are worsened

Engineering Contradiction:
Improvecommunication capabilityVSAvoidprivacy and anonymity
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces an intermediary messaging service that acts as a mediator between users and third parties. Users create accounts with this service that provide temporary, disposable messaging addresses rather than their primary email addresses. The intermediary service handles all communications, filtering and routing messages while maintaining user anonymity. This resolves the contradiction by enabling communication capability while preventing direct exposure of personal identifying information.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates copies of messaging addresses that are temporary and disposable rather than using the user's primary address. These copied addresses can be discarded after use, allowing users to communicate multiple times without repeatedly exposing their primary email address. The copying principle enables ongoing communication capability while protecting the original personal information through repeated use of disposable substitutes.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If users share personal information to establish online presence, then connectivity and functionality are improved, but vulnerability to unwanted marketing and information exposure is worsened

Engineering Contradiction:
Improveonline presence connectivityVSAvoidunwanted marketing and information exposure
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements disposable messaging addresses that can be created, used, and discarded without consequence. These short-living objects serve their purpose of enabling initial communication and online presence establishment, then are thrown away to prevent future unwanted marketing and information exposure. This resolves the contradiction by providing sufficient connectivity functionality through temporary addresses while eliminating long-term vulnerability through their disposable nature.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent extracts the essential messaging functionality from the user's primary personal information and separates it into independent, disposable messaging addresses. This extraction allows users to maintain online presence and connectivity without being forced to share or repeatedly expose their primary email address and personal information, thereby reducing vulnerability to harmful factors while preserving functional connectivity.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Disclosed are various embodiments for implementing a decentralized messaging system that allows users to exchange messages via an inbox maintained through a distributed ledger. A messaging inbox can be created for a user in a distributed ledger using an inbox address that includes a string of alphanumeric numbers without an identifying domain name or identifying information about the user. Furthermore, a user may define content preferences associated with the inbox that can be used by the distributed ledger to filter content received in the inbox to minimize unwanted or undesired content provided to the user.
