Blockchain Wallet Verification System for KYC Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain wallet owners' identities are difficult to verify without compromising their personal information, and service providers face risks such as money laundering due to the anonymous nature of blockchain transactions, making it challenging to comply with Know-Your-Customer (KYC) regulations.
Innovation Solution
A central system that stores blockchain wallet addresses and verification statuses, providing access management to client systems by associating wallets with specific access permissions based on verification status, allowing for separate access permissions for each provider and automatic or manual configuration without revealing identity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If blockchain wallet transactions remain anonymous to protect personal information, then user privacy is improved, but service providers cannot verify customer identities leading to money laundering risks
Solution Approach 1:
The patent introduces a verification system that acts as an intermediary between blockchain wallets and service providers. This system verifies customer identities and issues cryptographic proofs without revealing personal information to service providers, thus maintaining privacy while enabling KYC compliance. The intermediary holds the sensitive information and only shares verification results.
Solution Approach 2:
The patent extracts the identity verification function from the service provider and places it in a separate verification system. Service providers only receive cryptographic proofs of verification status without accessing actual personal information. This separation allows service providers to comply with KYC regulations while maintaining customer privacy.
2Reliability
If service providers implement their own identity verification, then KYC compliance is improved, but system complexity and verification costs increase
Solution Approach 1:
The patent creates a universal verification system that serves multiple service providers simultaneously. Instead of each provider implementing separate verification systems, a single verification system issues cryptographic proofs that are recognized across multiple platforms, reducing overall system complexity and avoiding duplicate verification efforts.
Solution Approach 2:
The verification system automatically verifies customer identities and issues cryptographic proofs without requiring service providers to conduct their own verification processes. Customers can obtain verification credentials once and use them across multiple service providers, eliminating the need for repeated verification and reducing system complexity.
3Ease of operation
If all verified wallets are granted universal access to all providers, then ease of use is improved, but security and access control flexibility deteriorate
Solution Approach 1:
The patent implements dynamic access permissions where service providers can configure different access levels for verified wallets based on their specific requirements. Access permissions are not static but can be adjusted per provider, per wallet, allowing flexibility in granting or denying access to specific features or functions while maintaining ease of use for authorized transactions.
Data Source
AI summary
A central system includes processor(s) and a memory storing instructions. The instructions, when executed by the processor(s), cause the central system to: store blockchain wallet addresses for blockchain wallets; store a verification status of each blockchain wallet, where each verification status indicates whether the owner identity of the respective blockchain wallet has been verified; and provide access management for client systems. The access management includes, for each client system: associating a subset of the blockchain wallets with the client system, where the subset contains blockchain wallets that are enrolled with the client system, and storing an access permission for each enrolled blockchain wallet for the client system. The central system, in response to a request from a particular client system regarding a particular blockchain wallet, communicates, to the particular client system, the access permission for the particular blockchain wallet for the particular client system.
