we could create a block chain system which allow users to send data to a blockchain which de-identifies the user specific information such as name, location, etc. for example,
1. name or id will be replaced with something to prevent being used to identify a person. the ID may be replaced with something which can be used to correlate data set but can not be used to identify a user.
2. age can be mapped to an age group
3. location, optional
4. sex, optional
5. race, optional
The information posted onto the network if get confirmed, will receive points. transaction gets posted to the network once a day or every 6 hours. each transaction should contain a number of data points, for example, the vitals will be measured every 10 minutes, if post is done every 6 hours, then each transaction should contain 36 data points.
The data can be used to track population in a particular areas during a disaster. data can be correlated to some other statistics to predict the population.
