Hash-Based Identity Verification for Virtual Asset Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for verifying the originator and beneficiary in virtual asset transfers fail to adequately protect personal information and ensure accurate matching, leading to potential mismatches and security risks.
Innovation Solution
A method involving an electronic device that identifies and hashes personal information such as full names and dates of birth, then transmits these hashed values to verify if the originator and beneficiary match, using hash values to determine the validity of transfers and prevent unauthorized transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If personal information (full name, DOB) is transmitted in plain text for verification, then verification accuracy is improved, but personal information security deteriorates
Solution Approach 1:
The patent introduces hash values as an intermediary representation of personal information. Instead of transmitting plain text personal information (full name, DOB), the system transmits hash values generated from this data. The hash value serves as a mediator that preserves verification functionality while eliminating direct exposure of sensitive personal information. The beneficiary server can verify identity by comparing hash values without ever seeing the actual personal data.
Solution Approach 2:
The patent creates a cryptographic copy (hash value) of the personal information that can be transmitted and verified without exposing the original data. The hash value is a derived representation that maintains the essential verification property (uniqueness and matchability) while being irreversibly different from the original personal information, thus protecting the source data during transmission.
2Object-affected harmful factors
If hashed personal information is transmitted instead of original data, then personal information security is improved, but verification complexity increases
Solution Approach 1:
The patent performs the hashing operation in advance, before transmission. The sending device generates hash values from the personal information (full name, DOB) beforehand and includes these pre-computed hash values in the transfer instruction. This preliminary action eliminates the need for the receiving device to perform complex hashing or verification computations, simplifying the overall process while maintaining security.
3Speed
If original personal information is transmitted for verification, then verification speed is improved, but security protection deteriorates
Solution Approach 1:
The hash value acts as a lightweight intermediary that can be processed and compared just as efficiently as original data. Since hash values are fixed-length strings regardless of the input data size, they can be transmitted and verified at speeds comparable to or faster than original personal information, while providing cryptographic security protection throughout the transmission process.
Data Source
AI summary
A method of verifying a beneficiary is provided. The method may include identifying information regarding transfer of a virtual asset including full name data of an originator, date of birth (DOB) data of the originator and a beneficiary virtual asset address, identifying a hash value set of a full name of the originator generated based on the full name data of the originator and a hash value set of a DOB of the originator generated based on the DOB data of the originator, transmitting, to a beneficiary server, a verification request message including the hash value set of the full name of the originator, the hash value set of the DOB of the originator and the beneficiary virtual asset address, and receiving, from the beneficiary server, a response message including verification result information regarding whether the originator matches the beneficiary, which is generated based on the verification request message.
