## What is IOTIED HealthChain?

The HealthChain app allows for the aggregation of an individual’s health data and also gives the individual the option of selectively sharing such data. It is an app built using Apple Inc.'s APIs for Apple Health, HealthKit, or CareKit.
 
According to Apple’s HealthKit framework, the iPhone as well as other wearables and smart devices already do or can be enabled to collect and provide data to the Apple Health app. IOTIED’s HealthChain app then quantifies such data and creates a simplified version of it for the user.
 
The HealthChain app permits users to collect some or all their health data from such wearable devices and to create data sharing options including controlling the type of data to be shared, the quantity of data to be shared, who to share it with, and the frequency with which the data is to be shared. The user can also turn off sharing the data altogether, or resume sharing the data at some future time. Accordingly, users can collect their own health data, collate the data in any manner that they want, and share selective data with third parties of their choosing such as doctors, hospitals, caregivers, labs, pharmacists, health insurance, life insurance, and others.
 
IOTIED does not collect and store any data from individuals who use the HealthChain app. All data always remains the exclusive property of the user. In other words, IOTIED’s HealthChain App is only a means whereby users control the inflow and outflow of their own health data as well as a repository where an individual’s personal health data is stored. And since the health data is aggregated and stored in a permissive blockchain environment, it is very difficult if not impossible, for even IOTIED to access such personal health data.
SAS IOTIED (France) has a subsidiary IOTIED Corporation (Delaware, USA), developed the HealthChain app in a permissive blockchain system, and the app remains the exclusive property of SAS IOTIED.
