We should promote greater data protection and privacy, but we shouldn’t ignore the incredible opportunities we can gain from personal data too. People seem worried about privacy and personal data, even though few know what data they actually have. On the bad side, a lot of talk centers on privacy concerns, especially in relation to social media and internet usage but also go back to revelations about government surveillance and our smart phone data too. On the good side, they can be used to help us know more about our health and behaviors. Our smartphones are incredible mini-trackers that can be used for both good and bad. Our phones contain sensors that detect movements, determine magnetic north, and even pinpoint us in relation to rotating satellites. We call these devices “smartphones,” and they have more computing power and memory than the Apollo Space Capsules did when they went to the moon. Most of us walk around carrying a small, sensor-infused computer.
