Solution Overview
Problem
Existing systems lack the ability to accurately track and record trends of service provision to users across multiple service providers, making it difficult to create effective plans that meet user and provider needs.
Innovation Solution
A data recording device and method utilizing blockchain technology to generate and store blocks containing user ID, service provider information, and service content data, with face authentication ensuring secure and accurate recording of service interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used to record service provision data, then data reliability and security are improved, but device complexity increases
Solution Approach 1:
The patent introduces a data recording device as an intermediary component that mediates between service providers and the blockchain network. This intermediary handles the complexity of blockchain operations (block generation, data formatting, cryptographic operations) while presenting a simplified interface to service providers, thus maintaining data reliability through blockchain while reducing perceived system complexity for end users
Solution Approach 2:
The system is segmented into distinct functional modules: user management unit for handling user credentials, data recording unit for capturing service provision data, and block generation unit for creating blockchain blocks. This segmentation allows each component to specialize in specific tasks, improving reliability through focused functionality while making the overall complex system more manageable and maintainable
2Measurement precision
If face authentication is implemented for service verification, then measurement precision of user identity is improved, but ease of operation deteriorates
Solution Approach 1:
The face authentication system operates as a self-service mechanism where the user's own facial features serve as the authentication credential. The service provider's terminal captures and verifies the user's face against stored biometric data without requiring manual intervention from authentication administrators, thus maintaining high verification accuracy while simplifying the operational process for both users and providers
3Adaptability or versatility
If multiple service providers are integrated into a unified plan, then adaptability of the service system is improved, but device complexity increases
Solution Approach 1:
The data recording device is designed with universal functionality to handle diverse service provision data from multiple different service providers within a single system. It can record various types of service data (different formats, providers, service types) through a unified interface and process them through standardized block generation, thus achieving high adaptability while managing complexity through standardization

AI summary
A block generation unit 13 generates, in a predetermined case, a block including an ID of a user in a blockchain. The block generation unit 13 generates a new block including information indicating a service provider and service contents, when face data of the user and the service contents are received from a terminal of the service provider and face authentication is successful based on the face data and face authentication data, or when the ID of the user and the service contents are received from the terminal of the service provider, and adds the new block to the blockchain.
