One does not need to know where you live, what you do every Thursday morning, if you are a sport freak or a couch potato, to offer you the best quality product or service. Likewise, one does not need to know how you walk, how fast you walk; what your head, shoulder or hand position is to ensure you an optimal experience.
Without data ever transmitted across the Internet, personal encrypted profiles can be stored on your devices, and access is only allowed after your permission is granted. It’s all about a vendor asking a simple and relevant question instead of mass data harvesting.
Examples could be: your age, your gender, your country location without any further intrusion. Because it is encrypted by the user’s own body, no one can read and collect the data without the user decrypting the relevant part. The data’s owner can customize such encrypted personal information files. It is up to you to decide if you add your name, address, gender, or date of birth. The user is left with the final decision to grant access to their minimal set of information for any probing vendor.
Likewise, via the NeuroPrint™ — if embedded in the driver’s seat — a car may 'know' that you are under influence and not able to drive without ever transmitting the data across the Internet. The information would stay local between the user and the car.
