Tokenized Reputation Cosigning for Secure Cross-Platform Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reputation systems fail to address the challenges of online transactions, leading to inefficiency, inaccuracy, discrimination, inadequate security, and lack of universal utility, particularly in international transactions, due to their centralized nature and limited transferability.
Innovation Solution
Utilizing tokenized reputation scores on a blockchain to generate and manage reputation scores for service provider accounts, enabling cosigning by accounts with sufficient reputation to back obligations of accounts with insufficient reputation, thereby controlling access to transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional centralized reputation techniques are used, then reputation can be established for online interactions, but the system is vulnerable to security breaches and lacks universality
Solution Approach 1:
The patent segments reputation data into transferable, ownable units called reputation tokens that can be divided and transferred independently. This allows reputation to be broken into portable components that can move between different service provider systems, enabling universality while maintaining security through distributed ownership rather than centralized storage.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer that mediates between users and service provider systems. The blockchain acts as a neutral, decentralized platform that stores and verifies reputation tokens without being controlled by any single service provider, thereby enhancing security while enabling cross-system portability and universality.
2Ease of operation
If centralized reputation systems are used, then reputation data can be stored and accessed, but users lose ownership and control of their reputation data
Solution Approach 1:
The patent implements self-service by giving users direct ownership and control of their reputation tokens through cryptographic key pairs. Users can independently store, transfer, and manage their own reputation data without requiring centralized intermediaries, thereby maintaining both accessibility and ownership simultaneously.
Solution Approach 2:
The patent inverts the conventional model by making users the owners of reputation data rather than the service providers. Instead of service providers storing user reputation data, users hold reputation tokens that they can present to service providers, flipping the ownership relationship to preserve user control while maintaining ease of access.
3Reliability
If cosigning based on tokenized reputation scores is implemented, then access control to transactions is improved, but system complexity increases
Solution Approach 1:
The patent changes the fundamental parameter of reputation from a centralized score to a tokenized, transferable asset with verifiable properties. This parameter change enables automated verification through cryptographic proof and smart contracts, improving access control reliability while the modular token structure actually reduces complexity compared to centralized systems.
Solution Approach 2:
The patent replaces mechanical centralized verification systems with cryptographic and automated smart contract-based verification. This substitution eliminates the need for complex centralized authorization workflows, as the blockchain automatically verifies token ownership and validity, thereby improving access control while reducing operational complexity.
Data Source
AI summary
Techniques are described, as implemented by computing devices, to control access to transactions through use of cosigning based on tokenized reputation scores. This is performed by leveraging a blockchain such that tokenized reputation scores are generated based on amounts of cryptographic reputation tokens associated with blockchain account addresses associated with applicant and co-signer service provider accounts. Transactional functionality is made available to an applicant service provider account having an insufficient tokenized reputation score by using a co-signer service provider account having a sufficient tokenized reputation score to at least partially back an obligation of the applicant service provider for a transaction.
