Are we crossing the line or this is an innovation to celebrate about?
While a lot of tools lately work with biometric data and they do need test data until they come as final product, hence harvesting biometric data can have a good side too, I fear that this is not enough and sooner or later they can get out in the wild - and getting on government hands is the least evil thing I would think about actually.
So I'd say that they're crossing the line.
I'd agree here with NeuroticFish because a while ago I saw some documentary or so and it was about how the human body can literally be broken down into mathematical equations. While that is great for medical science, the real question is what happens if health insurance companies get their hands on individual data sets? If a certain data set predicts specific health conditions significantly reliably or even only hints to potential health problems, what is going to happen to these individuals' insurance rates? It would completely undermine the idea of a solidly united society.
So the real question is: is it possible that the data gets into wrong hands? That question can certainly be answered with yes because as soon as that data is of significant value, rest assured it is accidentally going to be leaked into the wrong hands.
