Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fractured nature of existing identities and identity systems leads to inefficiencies and vulnerabilities, as they are often specialized for narrow purposes and susceptible to forgery, requiring multiple systems and lacking comprehensive functionality and security.
Innovation Solution
An identity score system that utilizes a blockchain to securely store and validate identity data, providing a unified, immutable, and flexible framework for identity verification and scoring across various contexts, enabling reliable and secure identity services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized identity systems are used for different purposes, then specific identification needs are met, but system complexity and inefficiency increase
Solution Approach 1:
The patent implements a universal identity system where a single identity token can serve multiple purposes across different contexts. The identity management platform enables one identity to be used for various identification needs (financial transactions, healthcare access, education verification, etc.) by dynamically configuring context-specific parameters and requirements, eliminating the need for multiple specialized identity systems.
Solution Approach 2:
The patent combines multiple identity verification functions into a single integrated identity token and platform. Rather than maintaining separate identity systems for different purposes, the invention merges these functions into a unified system where one identity token can satisfy multiple identification requirements through contextual parameter configuration.
2Reliability
If traditional identity systems are used, then basic identification is provided, but security against forgery and fraud remains vulnerable
Solution Approach 1:
The patent replaces traditional mechanical identity verification methods (physical documents, manual inspection) with cryptographic-based digital verification. Identity tokens use cryptographic signatures and blockchain technology to provide tamper-evident, forge-resistant identification that cannot be replicated by physical forgery methods.
Solution Approach 2:
The identity system combines multiple security layers including cryptographic signatures, blockchain immutability, contextual parameter validation, and decentralized verification mechanisms. This composite approach creates a robust identity verification system that resists various types of fraud through the integration of multiple security disciplines.
3Measurement precision
If context-specific identity parameters are implemented, then accurate identification for specific purposes is achieved, but information privacy and security requirements increase
Solution Approach 1:
The patent applies local quality by providing different levels of identity information disclosure based on the specific context. The identity token contains comprehensive identity data, but only the necessary portions are revealed for each verification context. For example, a healthcare context may require only medical record access verification, while a financial context may require only age verification, protecting unnecessary personal information from exposure.

AI summary
An embodiment of a method of providing identity services includes receiving identity data from an identity user, the identity data related to an identity of the identity user; receiving validation data from an identity provider, the validation data related to the identity data; if the validation data indicates that the identity data is valid, generating a transaction to store data related to the identity of the identity user on a blockchain of a blockchain system, the data to be stored including a representation of at least one of: the identity data, or the validation data; and transmitting the transaction to at least one distributed node of the blockchain system. An embodiment of a method of providing an identity score includes receiving an identity score request for an identity user from an identity score requestor; executing a read to at least one distributed node of a blockchain system to retrieve data related to one or more identities of the identity user stored on a blockchain of the blockchain system; for each of the one or more identities, determining a weight; and determining the identity score as a function of the weights for each of identities.
