Solution Overview

Problem

Existing technologies do not adequately address the secure storage and access of biological information from unspecified numbers of users, risking unauthorized access and network interception.

Innovation Solution

A biological information acquisition device that establishes a temporary connection with a user's terminal device via wireless communication, acquires and stores biological data in an external database server, shares a storage address, and ensures confidentiality through encryption and secure communication protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If biological information is stored in a database server accessible by terminal devices, then users can refer to their biological information conveniently, but the risk of unauthorized access and network interception increases

Engineering Contradiction:

Improveuser access to biological informationVSAvoidunauthorized access and network interception

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a database server as an intermediary between the biological information acquisition device and terminal devices. The server stores biological information and provides controlled access through storage addresses, mediating the interaction while maintaining security. This resolves the contradiction by enabling convenient user access through the intermediary while preventing direct unauthorized access to the acquisition device.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the biological information from the acquisition device and stores it separately in an external database server. Only storage addresses are transmitted to terminal devices, not the actual biological information data. This separation allows users to access their information conveniently through the server while the sensitive data remains secured in the database, preventing unauthorized access and network interception risks.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If connection history is retained for security monitoring, then unauthorized access can be detected, but the risk of information leakage through intercepted connection data increases

Engineering Contradiction:

Improvesecurity monitoring capabilityVSAvoidconnection history leakage

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent automatically deletes connection history from the database server after a predetermined period following the storage of biological information. This temporary retention allows for security monitoring during the active period, while subsequent deletion prevents long-term information leakage risks. The connection history is discarded after serving its security function, resolving the contradiction between monitoring capability and leakage prevention.

Inventive Principle:

Principle #34Discarding and recovering

3Ease of operation

If biological information is transmitted to terminal devices, then users can access their data, but the risk of network interception increases

Engineering Contradiction:

Improvedata accessibilityVSAvoidnetwork interception

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent transmits only storage addresses to terminal devices, not the actual biological information data. The terminal devices access the full information through these addresses via the database server. This extraction approach enables convenient data access while minimizing network transmission of sensitive information, thereby reducing interception risks.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The database server acts as an intermediary that holds the actual biological information securely while allowing terminal devices to access it through stored addresses. This mediation enables data accessibility for authorized users while keeping the sensitive information secured on the server, preventing network interception of the actual biological data.

Inventive Principle:

Principle #24Intermediary (Mediator)
