Blockchain Identity Verification via Cryptographic Hashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiency and repetition when undergoing lengthy validation processes for multiple service providers, such as cryptocurrency exchanges, due to the requirement of submitting identical identity documents, leading to time loss and inefficiency.
Innovation Solution
A method and system that forward verification data to a server, create a cryptographic hash, and return a package without retaining the data, allowing user identity confirmation via the hash, which is recorded on a distributed ledger like blockchain, enabling secure and efficient identity management across service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification data is retained on the server for identity confirmation, then identity verification reliability is improved, but data security and user privacy are worsened
Solution Approach 1:
The patent extracts only the essential verification information (cryptographic hash) from the complete verification data package, retaining only what is necessary for identity confirmation while removing sensitive personal information from server storage. This resolves the contradiction by maintaining verification reliability through hash comparison while eliminating data security risks associated with storing complete personal documents.
Solution Approach 2:
The system creates a cryptographic hash copy of the verification data that serves as a surrogate for the original sensitive information. This hash copy enables identity verification without requiring the server to store or handle the actual personal data, thus maintaining verification reliability while protecting user privacy and data security.
2Measurement precision
If complete verification data is stored on servers for multiple service providers, then identity confirmation accuracy is improved, but repetition and time loss across multiple providers increase
Solution Approach 1:
The patent creates a universal verification package with cryptographic hash that can be used across multiple service providers simultaneously. Once a user completes verification with one provider, the same hash-based verification package can be presented to other providers, eliminating the need to repeat the entire verification process and reducing time loss while maintaining confirmation accuracy through hash validation.
Solution Approach 2:
The system performs verification data processing and cryptographic hash creation in advance, before the user needs to access multiple service providers. This preliminary action prepares a ready-to-use verification package that can be quickly presented to multiple providers without requiring repeated verification processes, thus reducing time loss while maintaining accuracy.
3Reliability
If verification data is processed through multiple service providers, then comprehensive identity validation is improved, but complexity and inefficiency of the process increase
Solution Approach 1:
The cryptographic hash acts as an intermediary between the user's verification data and multiple service providers. Instead of each provider directly processing complete personal data, the hash serves as a standardized intermediate representation that enables comprehensive validation across providers while simplifying the overall process complexity through a unified verification mechanism.

AI summary
When a user signs-in to a service provider such as a cryptocurrency exchange, the user must undergo a lengthy validation process that involves submitting copies of identity documents or utility bills. Each such service provider requires the same type of documents, and this therefore leads to repetition, inefficiency, loss of time and/or loss of profit when multiple service providers are consulted. The present invention, allows a user's identity to be established before multiple service providers with only one manual validation.
