User Information Verification via Hash Comparison in Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users incorrectly determine the accuracy of their registered information due to format discrepancies, such as notational fluctuations or format errors, when comparing hash values generated by themselves and business operators.
Innovation Solution
A communication system and method that involves converting user information into a management format by business operators and transmitting a hash value and conversion content to user terminals, allowing users to verify the correctness of their information by recalculating the hash value and comparing it with the received hash value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the business operator converts user information into a unique management format, then the information can be standardized and managed efficiently, but the hash value changes and users cannot verify the correctness of their information
Solution Approach 1:
The business operator performs format conversion and hash calculation in advance, then transmits both the converted format specifications and the pre-calculated hash value to the user terminal. This allows the user to verify correctness without performing the conversion themselves, resolving the contradiction between standardized management and user verification.
2Ease of operation
If the user registers information in their own format, then the registration process is simple and user-friendly, but the information may not conform to the business operator's required format
Solution Approach 1:
The patent introduces an intermediary verification mechanism using hash values. The business operator's format conversion process acts as an intermediary that transforms user-friendly input into standardized storage format while maintaining verifiable correctness through hash comparison, thus bridging the gap between user convenience and format accuracy.
3Reliability
If the business operator transmits the converted format specifications to the user terminal, then the user can verify information correctness, but the communication data volume increases
Solution Approach 1:
The patent extracts only the essential verification elements (converted format specifications and hash value) from the complete user information and transmits them to the user terminal. This selective transmission provides verification capability while minimizing communication overhead by sending only what is necessary for verification rather than the entire information set.

AI summary
An communication program in which a business operator's terminal performs processing of conversion processing that converts user information acquired from an user into a management format and obtains converted user information, and confirmation request processing that calculates a first hash value obtained by hashing the converted user information with a first hash function, transmits a confirmation request including the first hash value, the first hash function, and conversion content of the conversion to the user, and requests the user to confirm validity of the user information managed.
