Multi-Encrypted Email Server Segmentation

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current email systems require multiple threads to be sent to manage different levels of encryption for recipients, leading to increased memory usage and processing bandwidth, as each recipient sees the entire email message, which is inefficient and cumbersome.

Innovation Solution

A server apparatus that processes multi-encrypted email messages by determining the encryption level of each message portion and generating individualized instances for recipients, masking portions that they are not intended to view, thereby maintaining a unified message thread while controlling information access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple email threads are created to limit who can read portions of a message, then information security is improved, but memory usage and processing bandwidth increase

Engineering Contradiction:

Improveinformation securityVSAvoidmemory usage

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The email message body is segmented into multiple portions, each with different encryption levels. The server receives a single email containing portions at different encryption levels and distributes them selectively to recipients based on their decryption capabilities, eliminating the need for multiple email threads while maintaining information security.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If multiple email threads are created to limit who can read portions of a message, then information security is improved, but processing bandwidth increases

Engineering Contradiction:

Improveinformation securityVSAvoidprocessing bandwidth

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

3Quantity of substance

If a single email message is sent to multiple recipients with different encryption levels, then memory usage is reduced, but device complexity increases

Engineering Contradiction:

Improvememory usageVSAvoidserver processing complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system employs automatic detection and routing mechanisms where the server autonomously identifies the encryption level of each message portion and automatically routes it to the appropriate recipient without manual intervention. This self-service approach manages the increased complexity through automation rather than manual processes.

Inventive Principle:

Principle #25Self-service

4Loss of information

If multiple email threads are created for different recipients, then information access control is improved, but the communication record becomes less manageable

Engineering Contradiction:

Improveinformation access controlVSAvoidcommunication record management

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

Multiple email threads that would traditionally be sent to different recipients are merged into a single email message with multiple portions at different encryption levels. The server handles the distribution and access control, consolidating what would have been separate communication threads into one manageable record while maintaining information access control.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An apparatus is configured to receive an email message that is addressed to a plurality of recipients. The email message comprises a first portion with a first level of encryption and a second portion with a second level of encryption. The apparatus creates a first instance of the message to be sent to a first recipient from among the plurality of recipients. In the first instance, the apparatus masks the portions of the message that are not of the first level of encryption. The apparatus creates a second instance of the message to be sent to a second recipient from among the plurality of recipients. In the second instance, the apparatus masks the portions of the message that are not of the first or second levels of encryption. The apparatus is further configured to transmit the first instance to the first recipient and the second instance to the second recipient.
