Solution Overview

Problem

Existing security technologies, such as the Data Encryption Standard (DES) scheme, fail to generate a key derived from the relationship between multimedia contents, making it difficult to protect multimedia information from unauthorized access during transmission.

Innovation Solution

The method involves transmitting multimedia content through a negative-base number system, where a binary sequence is generated, converted into a negative-base number, and used to derive a key for encryption based on the relationship between the content, enhancing security by using a computer system with a binary generator, negative base generator, encryptor, and decoder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional encryption schemes like DES are used, then encryption functionality is provided, but the ability to generate keys from relationships between multimedia contents is lost

Engineering Contradiction:

Improveability to generate keys from multimedia content relationshipsVSAvoidsecurity protection capability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the mathematical parameter base from conventional positive integers to negative integers. This parameter change enables the system to generate encryption keys by calculating the difference between negative-base number representations of multimedia contents, thereby achieving key derivation from content relationships while maintaining security

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces negative-base number representation as an intermediary mechanism between multimedia contents and encryption keys. This intermediary allows the system to transform content data into a mathematical representation that can be used to derive keys through subtraction operations, solving the problem of key generation from content relationships

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If multimedia content is transmitted directly, then transmission simplicity is maintained, but unauthorized access and information security are compromised

Engineering Contradiction:

Improveinformation securityVSAvoidtransmission system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by converting multimedia content into negative-base number representations before transmission. This pre-processing step encrypts the information in advance, preventing unauthorized access during transmission while maintaining a relatively simple transmission process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces conventional encryption mechanisms with a mathematical system based on negative-base number arithmetic. This substitution provides enhanced security through key derivation from content relationships while keeping the transmission system relatively simple

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
