Solution Overview

Problem

Existing digital asset management systems face challenges in securely and efficiently managing conditional access rights for digital assets, particularly in decentralized environments like blockchain networks.

Innovation Solution

The implementation of assignable tokens, which are smart contracts on a blockchain, allows for the secure assignment of conditional access rights. These tokens can be stored in one location but controlled by another party under specific conditions, utilizing a partitioning scheme and collateral manager functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If digital assets are stored in a decentralized ledger system, then security and transparency are improved, but access control and management complexity increase

Engineering Contradiction:

ImprovesecurityVSAvoidaccess control management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments access control into distinct conditional access rights that can be independently assigned and managed. Each digital asset has its own access control policy that can be divided into multiple conditional permissions, allowing different parties to have different levels of access under different conditions without requiring complex centralized management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces smart contracts as intermediary mechanisms that automatically enforce access control rules on the blockchain. These self-executing contracts act as mediators between asset owners and access seekers, automatically verifying conditions and granting or denying access without requiring manual intervention or complex centralized authorization systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conditional access rights are assigned to multiple parties, then asset utilization efficiency is improved, but security risks and fraud potential increase

Engineering Contradiction:

Improveasset utilization efficiencyVSAvoidsecurity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic access rights that can be automatically adjusted based on changing conditions. Access permissions are not static but can be modified in real-time based on predefined criteria such as time of day, completion of specific actions, or verification of conditions, allowing the system to adapt to different scenarios while maintaining security.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where the system continuously monitors access requests and automatically verifies whether conditions are met before granting access. This real-time feedback loop ensures that only authorized parties can access assets under the correct conditions, preventing fraud while enabling efficient multi-party utilization.

Inventive Principle:

Principle #23Feedback

3Productivity

If smart contracts are used to automate access control, then operational efficiency is improved, but system complexity and implementation difficulty increase

Engineering Contradiction:

Improveoperational efficiencyVSAvoidsystem implementation

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent designs smart contracts that are self-executing and self-enforcing, automatically managing access control without requiring external intervention. The contracts contain all necessary logic and conditions, enabling them to autonomously verify access requests, check conditions, and grant or deny permissions, thereby reducing operational overhead despite the initial implementation complexity.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If digital assets are made assignable and transferable, then market liquidity is improved, but control over asset usage may be compromised

Engineering Contradiction:

Improveasset transferabilityVSAvoidusage control

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates a universal access control framework that works across different types of digital assets and transfer scenarios. The same conditional access mechanism can be applied to various asset classes and transfer conditions, enabling flexible assignment and transfer while maintaining consistent control policies throughout the system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method includes storing, by a digital asset custodial device, assignable tokens to an address of a two-dimensional array structure with a first dimension that represents addresses and a second dimension that represents partitions. The method further includes assigning a partition to a network computing device of a cryptocurrency payment system, establishing a self-enforcing smart contract to assign an amount of the assignable tokens to the partition, and establish the self-enforcing smart contract to define conditional access rights in accordance with a set of conditions. The method further includes locking the amount of the assignable tokens in the address and providing the conditional access rights to the amount of the assignable tokens to the network computing device via the partition. The method further includes locking, by the network computing device, at least a portion of the amount of the assignable tokens to back one or more cryptocurrency-based payments.
