Fragmented Content Transmission via Multi-Channel Isolation

Solution Overview

Problem

Digital encryption technologies alone are insufficient in preventing unauthorized access to content, especially when faced with resourceful third parties.

Innovation Solution

Breaking content into multiple fragments and transmitting them over different physical channels, using unique session keys for encryption and decryption, and employing authentication with key providers to ensure secure reassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If digital encryption technology is used to protect content, then unauthorized access is prevented, but resourceful third parties can still obtain unauthorized access

Engineering Contradiction:

Improvecontent securityVSAvoidunauthorized access

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The content is divided into multiple fragments and transmitted through different physical channels. Each fragment alone is insufficient to reconstruct the original content, providing security against unauthorized access even if some fragments are intercepted. This segmentation approach directly addresses the limitation of traditional encryption by distributing security across multiple independent channels.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-channel encrypted transmission to a multi-dimensional approach using multiple physical channels. By adding the spatial dimension of multiple transmission paths, the system creates a more robust security model where compromise of one channel does not lead to complete content exposure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If content is broken into multiple fragments and transmitted over different physical channels, then privacy is enhanced, but system complexity increases

Engineering Contradiction:

Improveprivacy protectionVSAvoidtransmission system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The content is divided into multiple fragments and transmitted through different physical channels. Each fragment alone is insufficient to reconstruct the original content, providing security against unauthorized access even if some fragments are intercepted. This segmentation approach directly addresses the limitation of traditional encryption by distributing security across multiple independent channels.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses standard communication protocols and existing physical channel infrastructure (email providers, cloud storage services) to implement the multi-channel transmission. By leveraging universally available services, the patent reduces implementation complexity while maintaining the security benefits of fragmented transmission.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If session keys are used to encrypt fragments, then decryption capability is provided, but key management complexity increases

Engineering Contradiction:

Improvedecryption capabilityVSAvoidkey management complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

A key provider service acts as an intermediary between the sender and recipient for key management. The key provider generates, distributes, and manages the session keys used to encrypt and decrypt fragments, eliminating the need for complex peer-to-peer key exchange protocols and simplifying key management for the end users.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements automatic key generation and distribution through the key provider service, which handles key management tasks without requiring manual intervention. The sender and recipient automatically receive the necessary keys through the key provider, reducing the operational burden on users while maintaining secure decryption capabilities.

Inventive Principle:

Principle #25Self-service

AI summary

An example process includes breaking content into multiple fragments; and transmitting at least two of the multiple fragments over different physical channels in order to isolate the at least two fragments during transmission. The example process may include generating session keys; encrypting at least some of the fragments using different session keys; and associating, with each fragment, a session key used to encrypt a different fragment to produce fragment/session key pairs.
