Blockchain Identity Verification via Salted Side Chain Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity verification systems are not secure enough to prevent identity theft, as certifications can be discoverable, making it difficult to keep valuable information secret and effectively verify user identities to third parties.
Innovation Solution
A method and system that uses a blockchain to obfuscate user identity certifications with a unique salt, allowing users to login without usernames or passwords, and enables secure verification by generating a salt, hashing data with it, signing it with a private key, and storing it on a blockchain, with additional layers of obfuscation and verification through side chains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user identity certifications are stored on a blockchain, then verification reliability is improved, but security deteriorates because certifications become discoverable and can be associated with particular users
Solution Approach 1:
The patent introduces a salt value as an intermediary element between the user identity and the certification data stored on the blockchain. The salt is a random value that is hashed together with the certification data, creating an obfuscated representation that cannot be reverse-engineered to reveal the original identity. This intermediary layer maintains verification reliability while eliminating the security risk of direct identity exposure.
Solution Approach 2:
The patent transforms the certification data by applying cryptographic hashing functions with salt values, fundamentally changing the parameter representation of identity information. Instead of storing readable identity data, the system stores hashed representations that are computationally infeasible to reverse, thereby maintaining verification capability while eliminating discoverability risks.
2Ease of operation
If traditional username and password login is used, then ease of operation is maintained, but security deteriorates due to identity theft and credential compromise
Solution Approach 1:
The patent replaces the mechanical credential verification system (username and password checking) with a cryptographic proof system based on blockchain verification. Instead of relying on secret knowledge that can be stolen, the system uses cryptographic signatures and hashed identity proofs that are mathematically secure and cannot be compromised through traditional hacking methods.
3Difficulty of detecting and measuring
If certification data is made discoverable for verification purposes, then verification capability is improved, but loss of information increases as sensitive identity information becomes exposed
Solution Approach 1:
The salt value serves as a mediator that enables verification capability while protecting identity privacy. The hashed combination of certification data and salt can be verified against the blockchain without revealing the underlying identity information, thus achieving verification capability without the loss of sensitive information.
