Solution Overview

Problem

Current email systems fail to effectively segregate paid and unpaid emails, and lack robust antiphishing functionality, leading to issues with spam, phishing, and clutter, which affects both users and legitimate marketers, as existing filters and solutions are inadequate in distinguishing authentic from fraudulent emails.

Innovation Solution

A user interface that segregates Exsis emails into a separate inbox, using a source icon indicating micropayments or whitelist status, along with an antiphishing method that authenticates senders through a micropayment server, ensuring only authenticated emails from trusted sources are displayed as Exsis emails, with optional manual authentication and opt-out capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If all emails are displayed in a single inbox, then users can access all emails easily, but paid and unpaid emails become mixed together causing clutter and making it difficult to distinguish authentic emails from spam

Engineering Contradiction:
ImproveEmail accessibilityVSAvoidEmail segregation
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the email inbox into separate sections or categories, displaying paid emails (with stemps) and unpaid emails (without stemps) in distinct areas. This segmentation allows users to easily distinguish between authenticated and unauthenticated emails while maintaining easy access to all emails through a unified interface.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If micropayments are required for all emails, then spam is effectively reduced, but legitimate marketers face increased complexity and cost barriers

Engineering Contradiction:
ImproveSpam reductionVSAvoidPayment system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies micropayments selectively rather than universally. Emails from authenticated senders or those on whitelist databases can send without micropayments, while emails from unauthenticated sources require payments. This local quality approach reduces spam effectively while minimizing barriers for legitimate marketers who can establish authentication credentials.

Inventive Principle:
Principle #3Local quality

3Reliability

If sender authentication is implemented through micropayments, then phishing attempts are reduced, but the system complexity and transaction overhead increase

Engineering Contradiction:
ImproveEmail authenticityVSAvoidAuthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary authentication where senders are verified before their emails are delivered. The authentication process occurs in advance, with authenticated senders receiving stemps that are attached to their emails. This preliminary action ensures email authenticity while reducing the complexity of real-time verification during email delivery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary authentication system that mediates between senders and recipients. The micropayment server acts as a trusted intermediary that verifies sender identities and issues stemps, simplifying the authentication process for both senders and recipients while maintaining high reliability in email authenticity verification.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Loss of information

If emails are segregated into separate inboxes based on payment status, then email clarity is improved, but users lose the ability to view all emails in one place

Engineering Contradiction:
ImproveEmail clarityVSAvoidEmail navigation
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent creates a unified email interface that serves multiple functions simultaneously. The system can display all emails in a single view while also providing options to filter and segregate paid and unpaid emails. This multi-functionality allows users to maintain email clarity through segregation when needed while preserving the ability to view all emails in one place when desired.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A protocol for protected email transmission using micropayments and a segregated inbox in which protected emails are displayed. The protocol also involves authentication of the sender to defeat phishers and an opt out protocol which can be used to block protected emails from sources from which the user no longer wishes to receive emails even if the source has made a micropayment. Branded email is also taught wherein a sender of protected emails can pay extra to have a miniature version of its brand logo or trademark displayed with its email in the segregated inbox. A white list is maintained on the protected email server (along with the opt out black list) so that recipients can designate specific senders who may send email to that recipient without paying a micropayment and still have the protected email displayed in the segregated inbox.
