Linked Cryptographic Repositories for Secure Blockchain Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blockchain systems lack robust security mechanisms, particularly in decentralized applications, where users have limited recourse against unauthorized actions due to the decentralized nature and immutability of blockchain operations.
Innovation Solution
The system employs linked cryptography-based digital repositories with varying key structures to enhance security. A first digital wallet corresponds to a full private key stored on a user device, while a second digital wallet corresponds to partial private keys stored on both the user device and a remote device, ensuring shared control and minimizing the risk of security breaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single private key is stored on a user device for cryptography-based digital repository security, then the user has full control over digital assets, but the system is vulnerable to unauthorized access if the private key is compromised
Solution Approach 1:
The patent divides the private key into multiple segments (first partial private key and second partial private key) stored on different devices. The first partial private key is stored on the user device while the second partial private key is stored on a remote device. This segmentation ensures that no single device holds the complete private key, thereby reducing the risk of unauthorized access while maintaining security.
2Adaptability or versatility
If decentralized blockchain operations are implemented without a central administrator, then the system achieves decentralization and immutability, but users have limited recourse against unauthorized actions
Solution Approach 1:
The patent introduces a multi-party computation mechanism as an intermediary layer between the user and the blockchain network. This mechanism allows multiple parties (user device and remote device) to jointly control digital assets through shared private keys, providing a form of recourse and oversight while maintaining decentralization. The intermediary computation process ensures that no single party can unilaterally execute transactions, thereby protecting users against unauthorized actions.
3Ease of operation
If digital assets are transferred to a second cryptography-based storage application for blockchain operations, then the system enables decentralized application interactions, but the assets are moved to a less secure state
Solution Approach 1:
The patent maintains segmentation of the private key across multiple devices even when enabling blockchain operations. The first cryptography-based storage application holds the first partial private key and the second cryptography-based storage application holds the second partial private key. This segmentation allows the system to enable decentralized application interactions while ensuring that neither application alone has full access to the digital assets, thereby maintaining security while improving operational capability.

AI summary
Methods and systems disclosed herein recite the use of linking cryptography-based digital repositories in order to perform blockchain operations in decentralized applications. For example, the system may link a first cryptography-based, storage application (e.g., a first digital wallet) with a second first cryptography-based, storage application (e.g., a second digital wallet). The first cryptography-based, storage application may correspond to a first private key, and wherein the first private key is stored on a first user device. The second cryptography-based, storage application corresponds to a first partial private key and a second partial private key, wherein the first partial private key is stored on a first remote device, and wherein the second partial private key is stored on the first user device.
