Information Intermediating Apparatus Hash Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital content transactions over communication networks, existing systems face challenges in preventing information leakage and unfair acts, such as fraud, which can occur due to the centralization of transaction data in intermediating apparatuses, making them vulnerable to attacks.
Innovation Solution
An information intermediating apparatus is configured with a communication network-connected information providing apparatus and acquiring apparatus, utilizing cryptographic keys and hash values to verify the identity and integrity of transaction object information, ensuring that the intermediating apparatus does not store transaction data, thereby minimizing the risk of information leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transaction data is centralized in intermediating apparatus, then transaction management is simplified, but information leakage risk increases
Solution Approach 1:
The patent extracts the harmful element (raw transaction data) from the intermediating apparatus while retaining the useful function (transaction verification). Only cryptographic hashes and verification data are stored in the intermediating apparatus, while the actual transaction objects remain distributed between providing and acquiring apparatuses. This extraction eliminates the information leakage risk while maintaining centralized transaction management capabilities.
Solution Approach 2:
The patent introduces cryptographic hashes as an intermediary representation of transaction data. Instead of storing or processing actual transaction objects, the intermediating apparatus works with hash values that serve as secure proxies. This intermediary layer enables transaction verification and management without exposing sensitive information, resolving the contradiction between centralized management and information security.
2Reliability
If cryptographic verification is implemented, then transaction security is improved, but system complexity increases
Solution Approach 1:
The patent segments the cryptographic verification process into distinct, specialized components: hash generation at the source, hash storage in the intermediating apparatus, and hash verification at the destination. Each apparatus has a simplified, dedicated function rather than requiring full cryptographic capability. This segmentation reduces overall system complexity while maintaining high security through specialized cryptographic operations.

AI summary
An information intermediating apparatus in an information transaction system including an information providing apparatus, an information acquiring apparatus and the information intermediating apparatus connected to a communication network, includes: a first receiver that receives second information, of first and second information necessary for restoring transaction object information, and first feature information indicating a feature of the first information; a second receiver that receives second feature information from the information acquiring apparatus, the second feature information being calculated from the first information transmitted to the information acquiring apparatus from the information providing apparatus; a feature information determination unit that determines whether an identity is present between the first feature information and the second feature information; and a transmitter that transmits the second information to the information acquiring apparatus, when the feature information determination unit determines that the identity is present between the first feature information and the second feature information.
