Solution Overview
Problem
Current endoscope systems lack secure and efficient two-way communication protocols between endoscope processors and terminal devices, which are essential for authenticating users and enabling secure image processing and data transmission during medical procedures.
Innovation Solution
The endoscope system incorporates a processor configured for image processing and a terminal device with a transceiver and controller that authenticate users and establish secure two-way communication based on identification information, ensuring only registered users can access and transmit endoscope image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two-way communication is enabled between processor and terminal device, then data transmission efficiency is improved, but security risk increases
Solution Approach 1:
The patent introduces an authentication server as an intermediary between the terminal device and processor. The authentication server verifies user credentials and manages authentication tokens, acting as a trusted mediator that enables secure two-way communication without compromising system security. This resolves the contradiction by allowing efficient data transmission through authenticated channels while maintaining security through centralized authentication management.
Solution Approach 2:
The patent implements preliminary authentication actions before establishing two-way communication. The terminal device must first authenticate with the authentication server, obtain valid credentials, and establish trusted connections before any data transmission occurs. This preliminary security measure ensures that subsequent high-efficiency data communication occurs only through verified secure channels, resolving the contradiction between transmission efficiency and security.
2Reliability
If authentication procedures are implemented, then security is improved, but operation complexity increases
Solution Approach 1:
The patent implements self-service authentication mechanisms where the terminal device automatically manages authentication tokens, credentials, and security certificates without requiring manual user intervention for each authentication event. The system autonomously handles authentication procedures, resolving the contradiction by maintaining high security through automated authentication while reducing operational complexity by eliminating manual authentication steps.
Solution Approach 2:
The authentication server provides universal authentication services that can be applied across multiple terminal devices and processors using standardized protocols. This multi-functional authentication system handles various authentication types (user credentials, device certificates, tokens) through a single unified mechanism, resolving the contradiction by maintaining security through comprehensive authentication while simplifying operations through standardized universal procedures.
3Reliability
If user authentication is required, then access control is improved, but communication speed decreases
Solution Approach 1:
The patent performs authentication as a preliminary action before establishing communication channels. Once authentication is complete and trust is established, the system maintains open communication channels without requiring repeated authentication checks during data transmission. This resolves the contradiction by ensuring strict access control through preliminary authentication while maintaining high communication speed during actual data transfer operations.
Solution Approach 2:
The authentication server provides feedback in the form of authentication tokens and session identifiers that validate subsequent communication requests. Once a user is authenticated, the system uses these feedback tokens to rapidly verify subsequent access requests without repeating full authentication procedures, resolving the contradiction by maintaining strong access control through token-based verification while achieving high-speed communication through streamlined re-verification processes.
Data Source
AI summary
An endoscope system includes a processor that performs image processing on endoscope image data acquired by an endoscope, which is inserted in a subject and observes an inside of the subject. The processor communicate with a terminal device including a transceiver configured to transmit identification information identifying the terminal device, and a controller configured to: determine whether the processor is a connection destination configured to perform two-way communication, based on the received processor identification information, authenticate whether a user of the terminal device is a predetermined registered user by analyzing data obtained by the terminal device from the user, and allow two-way communication between the processor and the terminal device in response to the processor being determined as the connection designation to perform two-way communication and in response to authenticating the user of the terminal device.
