Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securely accessing resources across global or cloud computer networks is challenging due to authentication complexity, data protection, network security, latency, and compliance with diverse regulatory requirements, exacerbated by evolving cyber threats and reliance on vulnerable centralized systems.
Innovation Solution
Utilizing token-specific self-executing programs on blockchain networks to automate trustless transactions and enforce predefined rules, ensuring transparency, immutability, and resistance to tampering, by binding access permissions and transaction logic to a distinct token, thereby reducing fraud and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized authentication systems and databases are used for resource access control, then access management can be implemented, but security is compromised due to vulnerability to phishing, credential leaks, and insider threats
Solution Approach 1:
The patent extracts authentication credentials from centralized databases and stores them on-chain as NFTs. Each NFT contains unique access rights and permissions that are immutably recorded on the blockchain, eliminating the centralized database that is vulnerable to credential theft. Users prove their identity and access rights through cryptographic proofs derived from their NFTs rather than relying on stored passwords or API keys.
Solution Approach 2:
The patent creates a cryptographic copy of the access control system on the blockchain. Instead of storing credentials in a centralized database, the system creates immutable copies of access rights as NFTs that can be verified by any node in the network. This distributed copying eliminates single points of failure and ensures that even if the original credential system is compromised, the blockchain-based copies remain secure.
2Ease of operation
If traditional access control mechanisms relying on passwords and API keys are used, then resource access can be managed, but fraud and unauthorized access increase due to credential vulnerabilities
Solution Approach 1:
The patent implements self-service authentication where users prove their identity and access rights through their NFTs without requiring manual verification or intermediary approval. The blockchain system automatically validates cryptographic proofs and executes access control logic, eliminating the need for centralized authentication services and reducing human error in the access management process.
Solution Approach 2:
The patent replaces the mechanical system of passwords, API keys, and manual authentication with a cryptographic system based on blockchain technology. Instead of relying on text-based credentials that can be stolen or guessed, the system uses cryptographic hashes, digital signatures, and NFTs that are mathematically secure and cannot be replicated without the private key.
3Reliability
If blockchain-based token-specific self-executing programs are used, then security and transparency are enhanced, but system complexity increases
Solution Approach 1:
The patent segments the access control system into distinct modular components: NFTs for storing access rights, smart contracts for executing access control logic, and cryptographic proofs for authentication. This segmentation allows each component to be independently developed, tested, and optimized, reducing the overall complexity of the system while maintaining high security standards.
Solution Approach 2:
The patent creates a universal access control framework using NFTs that can be applied across multiple resources and systems. The same NFT-based authentication mechanism works for accessing different cloud resources, databases, and applications, eliminating the need for separate access control systems for each resource and reducing implementation complexity.
4Productivity
If centralized identity providers and databases are used, then authentication can be performed, but data protection is compromised due to potential data breaches
Solution Approach 1:
The patent extracts sensitive user data and authentication information from centralized databases and moves them to the blockchain. Instead of storing passwords, emails, and other personal information in vulnerable databases, the system stores only cryptographic hashes and NFTs that can be verified without exposing the original data, eliminating the risk of data breaches.
Solution Approach 2:
The patent introduces cryptographic proofs and NFTs as intermediaries between users and the blockchain. Instead of directly storing and transmitting sensitive user data, the system uses these intermediary elements that verify user identity and access rights without revealing underlying information, protecting data while enabling authentication.

AI summary
Systems and methods for securely accessing resources across global or cloud computer networks. In particular, systems and methods for using token-specific self-executing programs to securely access resources. For example, the use of token-specific self-executing programs, such as smart contracts designed to exchange a single NFT representing an off-chain product, enhances security in accessing resources by automating trustless transactions and enforcing predefined rules without intermediaries.
