Medical Measurement Device Secure Pairing Without Authentication Input

Solution Overview

Problem

Conventional medical measurement devices face challenges in simplifying communication settings with external devices while preventing unauthorized or erroneous connections, which can lead to data leakage and security issues.

Innovation Solution

A medical measurement device that acquires and transmits data without requiring user-input authentication, using a setting portion to specify and record external devices for communication, and transmitting identification and confirmation information to ensure secure data handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authentication information input is required for establishing communication, then security against unauthorized access is improved, but operation complexity and user burden increase

Engineering Contradiction:

ImprovesecurityVSAvoidoperation complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary pairing registration between the measurement device and external device before actual data transmission. During this preliminary phase, communication conditions and authentication parameters are pre-established, so that when actual communication occurs, the devices can transmit data securely without requiring users to input authentication information each time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces a pairing management mechanism as an intermediary between authentication and data transmission. This intermediary layer handles the complex authentication processes during the pairing phase, and once paired, enables straightforward communication without repeated authentication inputs, thus mediating between security requirements and ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A measurement device includes: a measurement portion that acquires measurement data; a setting portion that specifies an external device as a transmission destination of the measurement data based on a signal transmitted from the external device, and allows communication with the external device without receiving input of authentication information; and a transmission and reception portion that transmits measurement data to the external device. The setting portion causes the transmission and reception portion to transmit identification information of the measurement device to the external device, and further to transmit confirmation information thereto in addition to the identification information. The confirmation information is used by the external device to decide whether or not the external device can handle the measurement data transmitted from the measurement device.
