Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional digital transaction systems rely heavily on real-time online validations, leading to delays and increased costs, especially for low-value transactions, and lack efficient mechanisms for secure, low-latency, and cost-effective transactions.

Innovation Solution

The system employs a digital ecosystem with a centralized transaction ledger managed by an issuer, utilizing a secure digital pocket (SDP) with a modified Harvard architecture to store and manage copy-protected files (DCF), ensuring security and efficiency through dedicated file systems, communication protocols, and offline transaction capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time online validations are used in traditional digital transaction systems, then transaction security is improved, but transaction latency increases and costs increase

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-validating transactions offline before execution. The offline validation mechanism pre-checks transaction legitimacy and stores validation results, so that when transactions need to be executed, they can be processed quickly without requiring real-time online validation, thus reducing latency while maintaining security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary validation layer that acts as a mediator between online and offline validation systems. This intermediary component handles the transition and coordination between offline pre-validation and online execution, enabling secure transactions without requiring continuous real-time online verification, thereby reducing transaction time and costs

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If real-time online validations are used in traditional digital transaction systems, then transaction security is improved, but transaction costs increase

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction costs

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary validation actions offline before transactions are executed. By pre-validating transactions and storing the results, the system eliminates the need for expensive real-time online validation during transaction execution, significantly reducing transaction costs while maintaining security through the preliminary offline validation layer

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses a cost-effective offline validation mechanism that replaces expensive real-time online validation services. The offline validation system acts as a disposable, low-cost alternative that provides sufficient security for transactions without requiring continuous payment for expensive online validation infrastructure

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If traditional transaction channels are used, then transaction security is maintained, but infrastructure costs and maintenance costs are high

Engineering Contradiction:

Improvetransaction securityVSAvoidinfrastructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts the essential security validation function from complex online infrastructure and implements it as a simplified offline mechanism. By taking out the core validation capability and implementing it offline, the system maintains security while dramatically reducing infrastructure complexity and maintenance requirements

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system replaces expensive, complex online validation infrastructure with a simpler, cost-effective offline validation system. This disposable-like approach uses minimal infrastructure resources while providing sufficient security, eliminating the need for costly maintenance and scaling of complex online systems

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Reliability

If traditional online validation systems are used, then transaction security is ensured, but scalability and transaction volume handling become problematic

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction throughput

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary validation actions offline in advance, so that when high volumes of transactions need to be processed, the pre-validating transactions can be executed quickly without blocking for online validation. This enables the system to handle large transaction volumes efficiently while maintaining security through the preliminary offline validation layer

Inventive Principle:

Principle #10Preliminary action

AI summary

Systems and methods for transactions using digital currency based on copy-protected files are disclosed. An issuer transfers digital currency to a secure wallet in the form of a digital pocket on a hardware device. The device user transfers digital currency offline and transactions are validated and synchronized both locally and by the issuer from a central server. A dedicated file type, file system, and communications protocol are used to create the ecosystem for transitions using the digital pocket.
