Using deep-learning neural networks to find hidden patterns and insights in that data.
Many of the things you haven’t explicitly told to the U.S. Government can be deduced from the things they have.
Ever-improving pattern-recognition systems that they are building (and others will inevitably follow) will be able to extrapolate your secrets, with a high degree of confidence, from the subtle cues and nuances inherent in your visible live profile.
In fact, between deep learning, “big data,” and increasingly ubiquitous cameras and other sensors, on drones and embedded virtually everywhere, they’re moving headlong towards a world where your live is owned by the U.S. Government.
