I think this is more a centralized project as the data will be gathered in the machines.
Actualy good thinking there.. unless the data is not kept in the machines...
If this is the case that the machines DO gather the info, how safe is it to have such machines with personal user data in it?
For now I can't imagine what other people would do with this data if they manage to "steal" it, but I don't know why it would be neccesary to keep the info after the person got his/her info from it.
Could be just printing out some numbers for the doctor and resest for the next user.
I agree. This is an anonymous diagnosis. Nowhere in the documents is it indicated about the collection of personal information. And if somewhere in the airport a person who ate fried and sweet food, suddenly see a diagnostic apparatus, and made a breath analysis, his result will be inaccurate. Such data does not represent a value, even if they are stored.
