Health Data Binding via Time-Stamped Device Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical measurement devices, such as shared household scales, often incorrectly associate health data with the wrong user due to lack of user identification, leading to inaccurate health tracking.
Innovation Solution
A system where a medical measurement device communicates with a health server through a communications device, using a device identifier to bind health data to the correct user, ensuring accurate association by comparing time-stamped data within a configurable window of time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a shared medical measurement device is used by multiple users, then device utilization and productivity are improved, but user identification accuracy and data association reliability deteriorate
Solution Approach 1:
The patent introduces a communications device as an intermediary between the medical measurement device and the health server. This intermediary captures user identification information (such as device identifiers from smartphones, tablets, or computers) and transmits it to the health server along with the health data. The intermediary solves the contradiction by enabling multi-user support while maintaining accurate user-data association through the use of unique identifiers transmitted via the communications device.
2Reliability
If user identification mechanisms are added to medical measurement devices, then user identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts the user identification function from the medical measurement device itself and places it in a separate communications device. The medical measurement device only needs to transmit health data, while the communications device handles user identification through its own identifier (such as a smartphone's device ID). This extraction reduces the complexity of the medical measurement device while maintaining accurate user identification through the communications device's capabilities.
Data Source
AI summary
Methods, systems, and products measure health data related to a user. A time-stamped device identifier is received that uniquely identifies a communications device. A time-stamped sensor measurement is separately-received. A difference in time between the time-stamped device identifier and the time-stamped sensor measurement is determined. When the difference in time is within a window of time, then the sensor measurement is associated with the device identifier.
