Solution Overview
Problem
Existing biological sample analysis devices face challenges in maintaining user authentication and data security when communication with authentication servers is disrupted, leading to compromised security and operational inefficiencies.
Innovation Solution
The device incorporates both online and offline authentication methods, allowing continued operation and restricted access during offline authentication to ensure data security and maintain device functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If online authentication is used to maintain high security level, then authentication security is improved, but device operation becomes unavailable when network communication fails
Solution Approach 1:
The authentication system dynamically switches between online and offline modes based on network availability. When the network is available, online authentication is used for high security. When network communication fails, the system automatically transitions to offline authentication mode, allowing the device to remain operational while maintaining appropriate security levels for the current context.
Solution Approach 2:
The authentication parameters are changed based on network status. Online authentication uses centralized server verification with strict security protocols. Offline authentication uses local stored credentials with modified verification parameters, allowing operation when network communication is unavailable while adjusting security expectations to match the operational context.
2Productivity
If offline authentication is implemented to maintain device operation during network failures, then device availability is improved, but authentication security level deteriorates
Solution Approach 1:
Offline authentication implements partial authentication functionality - it verifies user credentials locally but does not perform full centralized security verification. This partial action allows the device to remain operational during network failures while accepting reduced security verification, matching the authentication level to the operational context.
Solution Approach 2:
The system dynamically adjusts security levels based on operational needs. When offline, the authentication system operates at a lower security tier that permits device usage, but maintains sufficient verification to prevent unauthorized access. The security level is not fixed but adapts to network availability and operational context.
3Ease of operation
If offline authentication is allowed to maintain maintenance performance, then device accessibility is improved, but confidential data security is compromised
Solution Approach 1:
Different authentication modes are assigned different quality levels for data access. Online authentication grants access to all device functions including confidential data. Offline authentication grants access only to essential maintenance functions while restricting access to confidential data, creating local quality differences in security protection based on authentication mode.
Solution Approach 2:
The data access parameters are changed based on authentication mode. Offline authentication modifies the permissions and access controls, restricting which data and functions are accessible. This parameter change ensures that even though the device remains accessible for maintenance, confidential data protection is enhanced by limiting what offline-authenticated users can access.

AI summary
An analysis device according to the present disclosure, which obtains data about a sample, is characterized by comprising: a placement unit on which the sample is placed; a data obtaining unit which obtains data about the sample; a user interface unit which allows a user to make access to processing of the analysis device; a communication unit which communicates with an online authentication unit that authenticates the user online; an offline authentication unit which authenticates the user offline when the communication unit cannot communicate with the online authentication unit; and a restriction unit which restricts the processing accessible to the user when the user is authenticated by the offline authentication unit as compared to when the user is authenticated by the online authentication unit.
